PHP - Finding An Array In An Array Of Arrays

I have build a small form that take the zip code that user enter and if is on my list will redirect to a sub domain craigslist.   I was checking all the zip codes and is pretty hard to know to what bigger city to attribute the  given zip code and for that I was thinking to a simple idea to use, I am not sure how much exact will be but I think will do the trick for the moment.   The zip code range start from  00501 to 99950.    I create a array with the biggest city shown in craigslist and the zip code that correspond.    Now the tricky part, what I will do with the rest of the zip codes and my idea is to measure the distance from one to another zip code and which zip code from the array is closer from given one  to take it.

<?php 

$zip = $_GET['zip']; 


    $z = array (
36830 => array ( 'auburn.craigslist.org' ),
35242 => array ( 'bham.craigslist.org' ),
36301 => array ( 'dothan.craigslist.org' ),
35630 => array ( 'shoals.craigslist.org' ),
35901 => array ( 'gadsden.craigslist.org' )


?>




Exemple:

$zip= 36870 // the code received from the user

36870 - $array=  ( 'auburn.craigslist.org' ),
           (36830  = 40)
           (36301 = 569)
           (36911 = -41)  // the minus will be excluded
           (....etc)

After checking the zip code with  the ones from array, the smaller score will attribute the sub-domain  correspond from the array. I hope will don  t be the case when will get  the same result from two zip codes:)     Now I am using this rule:

$zip0 = (isset($z[$zip][0]) && $z[$zip][0] != '') ? $z[$zip][0] : 'craigslist.org/about/sites#US';

and I was thinking to redirect the user for a page to enter the state and the city. But I wish to make it more precises and not to involved the user so much.     But if there are any other suggestions I will be glad to hear them.

I have a list of IP addresses in an very very very large array in random order.

I am trying to find a way to determine if there are at least 8 IP addresses that are consecutive. I was thinking some sort of for loop after a sort but that seems very time consuming and I'm sure PHP has a better way...

Some searching online revealed this: http://bytes.com/topic/php/answers/12143-flagging-consecutive-numbers-data-set  Is this the way to go?

Any tips?

Thanks!

Hi folks, i have a complex problem (for me anyway) but i am sure with your help this can be sorted.

Problem number 1: I have a simple while loop, but its only showing 4 results when i know there are 5
I am missing something very simple i know:

$sql = ("SELECT * FROM postcode WHERE unid='1'")or die ('<p>There seems to be a problem, please try again soon.</p>');   
$result = mysql_query($sql,$con);
$row = @mysql_fetch_array($result);

$i=0;
while ($row = @mysql_fetch_assoc($result)){

  echo "newpoints[". $i++ ."] = new Array({$row['lat']}, {$row['long']}, icon0, '{$row['postcodename']}', '{$row['postcodename']}'); \n";

}

What am i missing here?


Problem number 2:

I have a bunch of latitude and longitude codes stored in the database.
On each page there will be a varied amount of these codes used, but with a max of 20.
I need to find the highest number and the lowest number of each lat and long then come up with a code that is in the middle, the idea of this is to center a map.
So for example there will be an array like this:
50.852293  -1.76088
51.252938  -0.76128
51.259583  -0.727168
51.274  -0.837
51.123106  -0.970657

First i need to find the highest number of the first code (51.274) then the lowest number (50.852293)
and then the highest number of the second code (-1.76088) then the lowest number (-0.727168)
Then work out an inbetween code using the highest and lowest codes for each.

Does anyone have a clue how to go about this? I am not the worlds best array technition or mathematician

Does anyone know a way of to find the 'coordinates' of a deeply nested key in a multidimensional array whilst using array_walk_recursive?

I am using array_walk_recursive() to stripslashes() of all values of an array. However I need to be able to get the full coordinates of a key if the said key is of a certain value. The function key() only seems to get the highest level key.

As a test I have the following array which has three occurrences of a key named 'date'. Upon each occurrence I want to be able to know exactly where in the array it is so i can call is directly later.


<?php

$pages = array(array("variation"=>"xccsdc",
"items"=>array(array("nm"=>"ss",
  "type"=>"ta",
  "kkl"=>"Prodion."
  ),
array("nm"=>"nm",
"type"=>"nwsfd",
"kkl"=>"nws fd",
"nws"=>array(array("date"=>"1328982639",
"kkl"=>"f nfgfgnfgn",
"title"=>"nfgn fgn fhn "
),
 array("date"=>"1328982632", 
   "kkl"=>"fgn fgn",
   "title"=>" fgn"
   )
  )
),
array("nm"=>"nm",
"type"=>"nwsfd",
"kkl"=>"nws fd",
"nws"=>array(array("date"=>"1328982655",
"kkl"=>" gh fgh","title"=>"n fgh n"
)
)
)
)
)
);

function test_print(&$item, $key, $pages)
{
if($key == 'date')
{
//strip the slashes
$item = stripslashes($item);

//if the key is 'date' which is deeply nested, return the key.
echo key(current($pages));

echo '<br/>';
}
}

array_walk_recursive($pages, 'test_print', $pages);

?>

What is returned from the 'test_print' function is:
Quote

variation
variation
variation



Is this because array_walk_recursive() does not move the internal pointer pointer along?

I found this thread on stackoverflow: http://stackoverflow.com/questions/3133054/php-find-key-position-in-multidimensional-array which has a great function for finding the key, however i'm struggling to get my head around how I can apply something like this whilst using array_walk_recursive().

Does anyone have any ideas?

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!
Carmen

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'
	)
);

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.

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

What might be the best way to code this?

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));

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.

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?

Hi,

I need some help getting my head around arrays.

I have a basket of fruit:

$basket=("Apple","$Orange","$Banana","$Banana","$Peach","$Apple","$Banana","$Orange","$Apple");

I want to distribute and share this basket of fruit into bowls, such that each bowl contains the following:

$bowl=("$Apple",$Orange,"$Banana","$Banana")

ie. One Apple, One Orange & Two Bananas.

I can't seem to figure out how to do it.

Thanks in advance.
