PHP - Fun With Arrays! Distribute An Array Into Groups/sets.

I'm trying to create a sitemap page. With Main categories and then sub categories. Some have no subcategories and some have a lot. I want them evenly distributed into each column. I can't seem to find a script. Can someone help? I want it to look similar to this http://www.walmart.com/cp/All-Departments/121828

Here is a small portion of the categories:
Code: [Select]
<ul class="dirlist">
   
         <li><a class="s1" href="Accessories.htm"><b>A</b>ccessories</a></li>

           
               <ul class="subcats">
               
                     <li><a href="Belts.htm">Belts</a></li>
               
                     <li><a href="Gloves-and-Mittens.htm">Gloves
&amp; Mittens</a></li>
               
               </ul>
           
         <li><a class="s1" href="Activewear.htm"><b>A</b>ctivewear</a></li>

           
         <li><a class="s1" href="Handbags-and-Luggage.htm"><b>H</b>andbags
&amp; Luggage</a></li>

           
               <ul class="subcats">
               
                     <li><a href="Backpacks.htm">Backpacks</a></li>

               
                     <li><a href="Briefcases.htm">Briefcases</a></li>
               
                     <li><a href="Computer-Bags.htm">Computer

               </ul>
           
          </ul>

Hi

I have a page which returns 2 rows of images max 5 in each.
Code is:

<?php
$query = mysql_query("SELECT COUNT(id) FROM " . $prev . "pics where id=" . $id . "");
list($number_records) = mysql_fetch_row($query);

if ($number_records >= 10 )
{
$number =10; //LIMIT IMAGES TO 10
}
else
{
$number =$number_records;
}

echo "<br />";

echo "Displaying $number of $number_records images";

?>



<div class="thumb-right">


        <dl>
   
            <?php for ($i = 0; $i < 5; $i++): ?>
               <dt>
                 <img src="../pics/<?php echo $images[$i]; ?>" alt="" width="120" height="120" class="border1"  /><br /><br />
               </dt>
            <?php endfor; ?>
        
        </dl>



</div>    


<div class="thumb-left">

<dl>
          
            <?php for ($i = 5; $i < $number; $i++): ?>
            <dt>
                  <img src="../pics/<?php echo $images[$i]; ?>" alt="" width="120" height="120" border="0" class="border1" /><br /><br />
            </dt>
            <?php endfor; ?>
         
        </dl>

</div>

This works fine if there are 10 images to display, but on occasions there may only be 7 for instance. This then puts 5 in the right column and only 2 in the left column which looks ugly.

Can someone suggest a way of calculating the total number of images and then displaying them say 4 in the left column and 3 in the right column for this example?

Thanks for your time

I sell a webscript which is written in the php language. What I want to do is create a license for each user and limit the script installation to one domain only.

Also, I want to distribute this same script as a free trial for 15 days. After that the user must upgrade. The script will call home to verify if the user has valid record in our server or not.

What's the best and "hard to crack" way to distribute license in that way?

Hey guys,   I have an array of names sorted alphabetically. I'm trying to loop through them and create new arrays keyed by the letters of the alphabet containing the names which start with that letter.     so in the end i'm trying to create something like this:   $newarray = array( 'a' => array('anna','alan','andrew'),                                'b' => array('bert','ben','bob'),
                               'c' => array('cait','carry'),                                  etc,etc );   thanks        

Hello,

I have three arrays of integers $arrayA, $arrayB, and $arrayC.  $ArrayA is a "master array" meaning the array I need to match the other two to.  $arrayB and $arrayC are generated by my functions in the application and meet specific criteria.  As such, arrays B and C will never have any intersecting values, but both should have matches in $arrayA, and I need to generate an array which contains only the values of arrayA which match either B or C.

  After finding some documentation here (http://www.metrocomp.mocsi.eu/w3/php/func_array_intersect.html)

I tried using array_intersect :

array_intersect ($arrayA, $arrayB, $arrayC)

However this does not work as described and returns no results as there are no values which are contained in all three arrays.

I wrote the below as a work around, and it works just fine but I would think there is a better way?

$temp1 = array_intersect($arrA, $arrB);
$temp2 = array_intersect($arrA, $arrC);
$temp3 = array_merge($temp1, $temp2);
$final_array = array_unique($temp3);


Thanks for looking!

I have a MySQL query that pulls multiple columns with many rows.  I want to break each column into its own array.
Here is what I have to this point but doesn't seem to be working.  Is this the right direction or is there something easier?
Thanks!

Code: [Select]

$query = "SELECT name, address, city, state FROM customers WHERE sku = '12345'";
$result = mysqli_query($dbc, $query) or die();

$name = array();
$address = array();
$city = array();
state = array();

while ($data = mysqli_fetch_assoc($result)) {
  $name = $data['name'];
  $address = $data['address'];
  $city = $data['city'];
  $state = $data['state'];
}

Here are the two arrays to compare.

Peopleskills            
PeopleID   SkillID
2          2   
2          7   
2          9
2              11
3          2
3                  12
3          14   
4          5
            
Equipskills            
EquipID   SkillID   
1                2          
1                9   
1               11   
2               5      
2               7      
2               9      
2               12   
2               13   
2               14   
3               2   
4               11      

The common link is SkillID.
Each EquipID has some required SkillIDs that people must have to operate that machine.
As long as a PeopleID has the required SkillIDs from the EquipSkills, that person has permission to that machine.
This will be used create a third array.
It will look something like the following.

                          EquipIDs
                      1     2     3     4     5     6     7     8      9      10       11     12
PeopleIDs   
2                    x     x
3                           x
4
5

What might be the best way to code this?

I have an array like this  

$rows = array(
	array(
		'fruit.name' => 'Apple',
		'fruit.colour' => 'Red',
		'fruit.weight' => '0.1',
		'vegetable.name' => 'Carrot',
		'vegetable.colour' => 'Orange',
		'vegetable.weight' => '0.05'
	),
	array(
		'fruit.name' => 'Banana',
		'fruit.colour' => 'Yellow',
		'fruit.weight' => '0.7',
		'vegetable.name' => 'Potato',
		'vegetable.colour' => 'Brown',
		'vegetable.weight' => '0.6'
	)
);

Hey Guys. I came across this code example below assigns array values to a private property. However the private property is not defined as an array. It was a bit confusing to me because I always thought you need to define  the property as an array first. If someone can please help me understand this concept I would really appreciate it.   Below is the code.

<?php 


class Product {

	public $name; 
	public $price; 

	function __construct($name, $price){
		$this->name = $name; 
		$this->price = $price;

	}


}


class ProcessSale {
	private $callbacks; // This holds an array but is not defined as an array?


	function registerCallback($callback) {
		if(!is_callable($callback)) {
			throw new Exception("Callback Is Not Callable");
			
		}
		$this->callbacks[] = $callback;
	}


	function sale($product) {
		print "{$product->name}: processing \n";
		foreach ($this->callbacks as $callback) {
			call_user_func($callback, $product);
		}
	}
}


$logger = function($product) {
	print "logging ({$product->name})\n";
};


$processor = new ProcessSale();
$processor->registerCallback($logger);

$processor->sale(new Product("shoes", 6));
echo  "\n";
$processor->sale(new Product("coffee", 6));

My array is

$arr = array(
	'global' => array(
		array('tabs', 'tabs', 'tabs', array(
			'Main' => 'main',
			'Gallery' => 'galleryID',
			'mera' => 'mera',
		)),

		array('main','div',  'div'),
		array('egice', 'Eice', 'text', '', ''),
		array('closeHere', 'closeHere', 'closeHere'),


		array('galleryID','div',  'div'),
		array('gallery', 'Gallery #1', 'image', '', ''),
		array('closeHere', 'closeHere', 'closeHere'),


		array('networking', 'div', 'div'),
		array('siLype', 'SiLype', 'text', '', ''),
		array('gpXCge', 'GpXCge',  'toggle_button', '1', 'Yes', 'No', ''),
		array('closeHere', 'closeHere', 'closeHere'),


		array('mera', 'div', 'div'),
		array('maimera', 'Maimera', 'repeatedText', 'resYI', 'GYL',''),
		array('closeHere', 'closeHere', 'closeHere'),



		array( 'moures','div', 'div'),
		array('meLmo', 'MeLmo', 'text', '', ''),
		array('cYSlot', 'CYSlot', 'text', '', ''),
		array('closeHere', 'closeHere', 'closeHere'),

		array('clT', 'clT', 'clT'),



	),

);

Simply, I want to split the main array to multiple arrays
extract new Array if “div” value found

I had tried here to do it but I can’t

Could you help?

Hello!   First of all, I'm new here. I've been working with PHP for a few months and am really enjoying its capabilities   A little background on the project I'm doing at the mo, I'm creating a small dashboard for grabbing Twitter stats via the API. The result will eventually output in a pretty table showing the daily followers, follower gains (or losses) etc. Here's an example of the table I eventually want to end up with.   So far I have two arrays of data:   $accounts_data is a list of all account names and their associated ID's $followers_data is a list of all follower counts, for a specific time of day, with an associated account ID (which matches the ID found in $accounts_data, thus pairing the follower count to a specific account)   I'm now trying to combine these two arrays into something more sensible that can then be used to output the table as shown in the link above.   $accounts_data:

array(4) {
  [0]=> array(2) {
    ["id"]=> string(4) "1279"
    ["name"]=> string(13) "AccountName1"
  }
  [1]=> array(2) {
    ["id"]=> string(4) "1280"
    ["name"]=> string(10) "AccountName2"
  }
  [2]=> array(2) {
    ["id"]=> string(4) "1281"
    ["name"]=> string(12) "AccountName3"
  }
  [3]=> array(2) {
    ["id"]=> string(4) "1283"
    ["name"]=> string(11) "AccountName4"
  }
}

$followers_data (truncated this data)  

array(12) {
  [0]=>
  array(3) {
    ["account_id"]=> string(4) "1279"
    ["date_time"]=> string(19) "2014-11-14 09:00:03"
    ["followers"]=> string(4) "1567"
  }
  [1]=>
  array(3) {
    ["account_id"]=> string(4) "1280"
    ["date_time"]=> string(19) "2014-11-14 09:00:29"
    ["followers"]=> string(4) "7688"
  }
  [4]=>
  array(3) {
    ["account_id"]=>
    string(4) "1279"
    ["date_time"]=>
    string(19) "2014-11-14 16:30:35"
    ["followers"]=>
    string(4) "1566"
  }
}

I have a really confusing question.  I dynamically generate arrays, but for the simplicity of the example we can just use two arrays.

Code: [Select]
Array 1 (
     [0] = 1
     [1] = 5
)

Array 2 (
     [0] = 2
     [1] = 6
)
How can I make the arrays multiple based on the same key value? 

array 1[0] * array 2[0] = 2
array 1[1] * array 2[1] = 30

I then want to sum the total of the multiplication.

$total = 2 + 30;

I need to do this to calculate covariance for a statistics procedure I am trying to run but I can't wrap my head around how to do the logic.

I suck with arrays, there I said it .  With that said, hopefully someone can help me here. I have two multi-dimensional arrays called $allteams and $chosenteams (the contents of which are listed below).  I simply want to compare them and make a new array of the items that are in the first array ($allteams) but NOT in the second array ($chosenteams). NOTE: I tried to use array_diff() but couldn't get it to work since they are multidimensional...

FYI, I'm also confused why the info appears to be listed twice but I think that just has to do with associative vs. numeric arrays (i.e. I think I just need to specify one and the amount info would be cut in half), but I'll research this more on my own as it seems like it has to be easy to find

$allteams

Array ( => Array ( => 1 [teamid] => 1 [1] => Philadelphia [teamcity] => Philadelphia [2] => Eagles [teamname] => Eagles ) [1] => Array ( => 2 [teamid] => 2 [1] => Dallas [teamcity] => Dallas [2] => Cowboys [teamname] => Cowboys ) [2] => Array ( => 3 [teamid] => 3 [1] => New York [teamcity] => New York [2] => Giants [teamname] => Giants ) [3] => Array ( => 4 [teamid] => 4 [1] => Washington [teamcity] => Washington [2] => Redskins [teamname] => Redskins ) [4] => Array ( => 5 [teamid] => 5 [1] => Detroit [teamcity] => Detroit [2] => Lions [teamname] => Lions ) [5] => Array ( => 6 [teamid] => 6 [1] => Minnesota [teamcity] => Minnesota [2] => Vikings [teamname] => Vikings ) [6] => Array ( => 7 [teamid] => 7 [1] => Green Bay [teamcity] => Green Bay [2] => Packers [teamname] => Packers ) [7] => Array ( => 8 [teamid] => 8 [1] => Chicago [teamcity] => Chicago [2] => Bears [teamname] => Bears ) [8] => Array ( => 9 [teamid] => 9 [1] => Tampa Bay [teamcity] => Tampa Bay [2] => Buccs [teamname] => Buccs ) [9] => Array ( => 10 [teamid] => 10 [1] => New Orleans [teamcity] => New Orleans [2] => Saints [teamname] => Saints ) [10] => Array ( => 11 [teamid] => 11 [1] => Carolina [teamcity] => Carolina [2] => Panthers [teamname] => Panthers ) [11] => Array ( => 12 [teamid] => 12 [1] => Atlanta [teamcity] => Atlanta [2] => Falcons [teamname] => Falcons ) [12] => Array ( => 13 [teamid] => 13 [1] => Seattle [teamcity] => Seattle [2] => Seahawks [teamname] => Seahawks ) [13] => Array ( => 14 [teamid] => 14 [1] => San Francisco [teamcity] => San Francisco [2] => 49ers [teamname] => 49ers ) [14] => Array ( => 15 [teamid] => 15 [1] => St. Louis [teamcity] => St. Louis [2] => Rams [teamname] => Rams ) [15] => Array ( => 16 [teamid] => 16 [1] => Arizona [teamcity] => Arizona [2] => Cardinals [teamname] => Cardinals ) [16] => Array ( => 17 [teamid] => 17 [1] => New York [teamcity] => New York [2] => Jets [teamname] => Jets ) [17] => Array ( => 18 [teamid] => 18 [1] => Miami [teamcity] => Miami [2] => Dolphins [teamname] => Dolphins ) [18] => Array ( => 19 [teamid] => 19 [1] => Buffalo [teamcity] => Buffalo [2] => Bills [teamname] => Bills ) [19] => Array ( => 20 [teamid] => 20 [1] => New England [teamcity] => New England [2] => Patriots [teamname] => Patriots ) [20] => Array ( => 21 [teamid] => 21 [1] => Baltimore [teamcity] => Baltimore [2] => Ravens [teamname] => Ravens ) [21] => Array ( => 22 [teamid] => 22 [1] => Cincinnati [teamcity] => Cincinnati [2] => Bengals [teamname] => Bengals ) [22] => Array ( => 23 [teamid] => 23 [1] => Pittsburgh [teamcity] => Pittsburgh [2] => Steelers [teamname] => Steelers ) [23] => Array ( => 24 [teamid] => 24 [1] => Cleveland [teamcity] => Cleveland [2] => Browns [teamname] => Browns ) [24] => Array ( => 25 [teamid] => 25 [1] => Houston [teamcity] => Houston [2] => Texans [teamname] => Texans ) [25] => Array ( => 26 [teamid] => 26 [1] => Tennessee [teamcity] => Tennessee [2] => Titans [teamname] => Titans ) [26] => Array ( => 27 [teamid] => 27 [1] => Jacksonville [teamcity] => Jacksonville [2] => Jaguars [teamname] => Jaguars ) [27] => Array ( => 28 [teamid] => 28 [1] => Indianapolis [teamcity] => Indianapolis [2] => Colts [teamname] => Colts ) [28] => Array ( => 29 [teamid] => 29 [1] => Denver [teamcity] => Denver [2] => Broncos [teamname] => Broncos ) [29] => Array ( => 30 [teamid] => 30 [1] => Kansas City [teamcity] => Kansas City [2] => Chiefs [teamname] => Chiefs ) [30] => Array ( => 31 [teamid] => 31 [1] => Oakland [teamcity] => Oakland [2] => Raiders [teamname] => Raiders ) [31] => Array ( => 32 [teamid] => 32 [1] => San Diego [teamcity] => San Diego [2] => Chargers [teamname] => Chargers ) )

$chosenteams

Array ( => Array ( => 2 [teamid] => 2 [1] => Dallas [teamcity] => Dallas [2] => Cowboys [teamname] => Cowboys ) [1] => Array ( => 3 [teamid] => 3 [1] => New York [teamcity] => New York [2] => Giants [teamname] => Giants ) )

Again, I just want to compare those two multi-dimensional arrays and end up with another array that only has the items that are in the first but NOT in the second.   So now I'm trying to do it the way below using simply "array_push" Code: [Select]
$remainingteams = array();
foreach($allteams as $teamname=> $value) {
if (in_array($teamname, $chosenteams)) {
} else {
array_push($remainingteams,$teamname);
}
}
My end result based on the way the arrays are in this example should be...

$remainingteams  (really the only difference is that the Cowboys and Giants info is gone)

Array ( => Array ( => 1 [teamid] => 1 [1] => Philadelphia [teamcity] => Philadelphia [2] => Eagles [teamname] => Eagles ) [3] => Array ( => 4 [teamid] => 4 [1] => Washington [teamcity] => Washington [2] => Redskins [teamname] => Redskins ) [4] => Array ( => 5 [teamid] => 5 [1] => Detroit [teamcity] => Detroit [2] => Lions [teamname] => Lions ) [5] => Array ( => 6 [teamid] => 6 [1] => Minnesota [teamcity] => Minnesota [2] => Vikings [teamname] => Vikings ) [6] => Array ( => 7 [teamid] => 7 [1] => Green Bay [teamcity] => Green Bay [2] => Packers [teamname] => Packers ) [7] => Array ( => 8 [teamid] => 8 [1] => Chicago [teamcity] => Chicago [2] => Bears [teamname] => Bears ) [8] => Array ( => 9 [teamid] => 9 [1] => Tampa Bay [teamcity] => Tampa Bay [2] => Buccs [teamname] => Buccs ) [9] => Array ( => 10 [teamid] => 10 [1] => New Orleans [teamcity] => New Orleans [2] => Saints [teamname] => Saints ) [10] => Array ( => 11 [teamid] => 11 [1] => Carolina [teamcity] => Carolina [2] => Panthers [teamname] => Panthers ) [11] => Array ( => 12 [teamid] => 12 [1] => Atlanta [teamcity] => Atlanta [2] => Falcons [teamname] => Falcons ) [12] => Array ( => 13 [teamid] => 13 [1] => Seattle [teamcity] => Seattle [2] => Seahawks [teamname] => Seahawks ) [13] => Array ( => 14 [teamid] => 14 [1] => San Francisco [teamcity] => San Francisco [2] => 49ers [teamname] => 49ers ) [14] => Array ( => 15 [teamid] => 15 [1] => St. Louis [teamcity] => St. Louis [2] => Rams [teamname] => Rams ) [15] => Array ( => 16 [teamid] => 16 [1] => Arizona [teamcity] => Arizona [2] => Cardinals [teamname] => Cardinals ) [16] => Array ( => 17 [teamid] => 17 [1] => New York [teamcity] => New York [2] => Jets [teamname] => Jets ) [17] => Array ( => 18 [teamid] => 18 [1] => Miami [teamcity] => Miami [2] => Dolphins [teamname] => Dolphins ) [18] => Array ( => 19 [teamid] => 19 [1] => Buffalo [teamcity] => Buffalo [2] => Bills [teamname] => Bills ) [19] => Array ( => 20 [teamid] => 20 [1] => New England [teamcity] => New England [2] => Patriots [teamname] => Patriots ) [20] => Array ( => 21 [teamid] => 21 [1] => Baltimore [teamcity] => Baltimore [2] => Ravens [teamname] => Ravens ) [21] => Array ( => 22 [teamid] => 22 [1] => Cincinnati [teamcity] => Cincinnati [2] => Bengals [teamname] => Bengals ) [22] => Array ( => 23 [teamid] => 23 [1] => Pittsburgh [teamcity] => Pittsburgh [2] => Steelers [teamname] => Steelers ) [23] => Array ( => 24 [teamid] => 24 [1] => Cleveland [teamcity] => Cleveland [2] => Browns [teamname] => Browns ) [24] => Array ( => 25 [teamid] => 25 [1] => Houston [teamcity] => Houston [2] => Texans [teamname] => Texans ) [25] => Array ( => 26 [teamid] => 26 [1] => Tennessee [teamcity] => Tennessee [2] => Titans [teamname] => Titans ) [26] => Array ( => 27 [teamid] => 27 [1] => Jacksonville [teamcity] => Jacksonville [2] => Jaguars [teamname] => Jaguars ) [27] => Array ( => 28 [teamid] => 28 [1] => Indianapolis [teamcity] => Indianapolis [2] => Colts [teamname] => Colts ) [28] => Array ( => 29 [teamid] => 29 [1] => Denver [teamcity] => Denver [2] => Broncos [teamname] => Broncos ) [29] => Array ( => 30 [teamid] => 30 [1] => Kansas City [teamcity] => Kansas City [2] => Chiefs [teamname] => Chiefs ) [30] => Array ( => 31 [teamid] => 31 [1] => Oakland [teamcity] => Oakland [2] => Raiders [teamname] => Raiders ) [31] => Array ( => 32 [teamid] => 32 [1] => San Diego [teamcity] => San Diego [2] => Chargers [teamname] => Chargers ) )

Can anyone help me figure this out?  i've been trying for hours (I know, that's pathetic )

Hi - I am passing $_POST data from an HTML form. The POST array looks like this:

Code: [Select]
       
Array
(
    [location] => Array
        (
            [0] => Collingwood
            [1] => Varsity
        )

    [4] => 01 Apr 2012
    [1] => 12 Apr 2012
    [2] => 01 May 2012
    [3] => 01 Jun 2014
    [8] => 01 Jul 2012
    [6] => 12 Aug 2012
    [7] => 20 Apr 2013
    [5] => 20 Apr 2014
    [submit] => Save Changes
)

I am using a foreach loop to separate the keys from the values.  The $values include dates and locations. I then pass $values to strtotime to convert the dates to a Unix Time stamp. when strtotime sees the Locations - it throws a PHP error "strtotime() expects parameter 1 to be string, array given"

so my question is what can I do to separate the Dates from the locations in order to avoid the error ?

MANY THANKS to anyone who can give advice on this !

As the title says, how can i check if multiple arrays exist inside an array or not?

Any help is greatly appreciated!
