PHP - Finding Array Within Range

I am trying to locate an array in an array of arrays:

    $card_pos = array_search($target, $_SESSION['leitner']['boxes'][($box - 1)]);
    if ($card_pos !== false) {
  // Do my stuff here
}echo '<pre> oh no -- didn\'t find '; print_r($target); echo "in ";print_r ($_SESSION['leitner']['boxes'][($box + 1)]);echo '<br>leitner';print_r ($_SESSION['leitner']); echo '</pre>';

but I don't find the target in the array though it is clearly there as you can see in the output:

oh no -- didn't find Array
(
    [pos] => v5g
    [tense] => agerimasu
)

        (

Hi PHPfreaks,

I've got a problem Ive been faced with a few days now, and for the life of me Im unable to solve it.

What I have is a multidimensional array, that I need to parse and retreive every possible outcome possible

Below is a basic example of how the array would look

Code: [Select]
Colour
        Black
        White
        Blue
Finish
        Matt
        Gloss

What I need to be able to do is, as I said, Show all the possible combinations there is.
below is what i'd have achieved after one of you helpful souls points me in the right direction.
Code: [Select]
--> Color: Black
--> Color: White   
--> Color: Blue
--> Finish: Matt       
--> Finish: Matt 
--> Color: Black, Finish: Matt       
--> Color: White, Finish: Matt     
--> Color: Blue, Finish: Matt       
--> Color: Black, Finish: Gloss     
--> Color: White, Finish: Gloss     
--> Color: Blue, Finish: Gloss     


As you can see, Only ONE (or no) value is picked from each section.

Just to confirm:
the number of option groups WILL change...... So I could have colour, finish, size, weight and many more.
the number of values in the groups WILL change....... so under colour, I could also have pink, green, indigo, gray.

Below is how this array is structured
Code: [Select]
Array
(
    [0] => Array
        (
            [parent] => Colour
            [values] => Array
                (
                    [0] => Array
                        (
                            [name] => Black
                        )
                    [1] => Array
                        (
                            [name] => White
                        )
                 )
        )

    [1] => Array
        (
            [parent] => Finish
            [values] => Array
                (
                    [0] => Array
                        (
                            [name] => Matt
                        )
                    [1] => Array
                        (
                            [name] => Gloss
                        )
                )
        )
)


Would anyone have any suggestion on how this can be done?
I've pulled out every single strand of hair I've got now, so thought i'd admit defeat and let someone else have a go



Many thanks inadvance.

Good day,

Is there a simple way to find and list duplicates i an array and insert these to a new one? I have:

$array[0] = "asd"
$array[1] = "ter"
$array[2] = "asd"
$array[3] = "asd"
$array[4] = "xfh"

From that, I need this:

$newarray[0] = "0"
$newarray[1] = "2"
$newarray[2] = "3"

I have poked around "array_not_unique" and "in_array" a bit, but can't wrap my head around it enough for it to work... Any and all help are much appreciated. Thanks in advance!

Thank You

I am having a go at writing my own simple gallery.

As the I want to display an image from a folder in a directory of all the images... for example, I have 10 folders each containing images. I want my code to take image 01.jpg out of each folder and display it on my page, so that when I add folders to my main images folder, they will automatically be added to the page... but I only want the last 10 folders to display... so once I have 20 folders, it only shows 10.

I also want the images to be 5 across and then make a new row.

My folders will be numbered in order... 001, 002, 003, etc... and I need them sorted in reverse order, so the folder added last is displayed first.

So... this is where I am at with the code :

Code: [Select]

$dir = "gallery/";

if (is_dir($dir)) {
[color=red]     foreach(array_keys($file) as $n) {[/color]
        if ($n+1 == 5) {
            echo "<td><img src=\"" . $dir . $file . "/01.jpg\" width=\"140px\" height=\"93px\" alt=\"\" /></td></tr><tr>";
        }
elseif ($n+1 > 10) {
echo "";
}
else {
echo "<td><img src=\"" . $dir . $file . "/01.jpg\" width=\"140px\" height=\"93px\" alt=\"\" /></td>";
}
        closedir($dh);
    }
}
For some reason, I am getting the following error on the page :

Warning: First argument to array_keys() should be an array in /path/to/gallery.php on line 8

Warning: Invalid argument supplied for foreach() in /path/to/gallery.php on line 8

line 8 is the one in red above.

So... I have a couple of questions...

1. What have I done wrong so far? I cannot see it 
2. How would I then go about putting the galleries in reverse order? I know it must be rsort, but not to sure if I need to do this first or after... ?

Any help greatly appreciated, and I would also be greatful f an idiot's explanation, as I am really trying to understand all this! 

I'm getting there... slowly! 

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.

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?

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!
Carmen

Why is this not working?
Code: [Select]
$result = mysql_query("SELECT * FROM contacts WHERE type = 'consumer' AND sent BETWEEN '".date("Y-m-d")."' AND '".date("Y-m-d", strtotime("-7 days"))."'")
or die(mysql_error());
$numrows = mysql_num_rows($result);
if($numrows < 0 ){
echo "No records found";
}

The record that is stored in the sent column is like this "2011-11-03 14:42:12", so there is a record in there, but nothing is showing up.

Can anyone see why?

thanks in advance

I am currently working on a date range script and wondering if anybody think of an easier way to do this, doing up to next 8 weeks?  This one starts on a Sunday. I also need to do one starting on a Monday (will figure that one later)

$thisweek = date("Y-m-d");
$week = date('w', strtotime($thisweek));
$date = new DateTime($thisweek);
$firstWeek = $date->modify("-".$week." day")->format("M d");
$endWeek = $date->modify("+6 day")->format("M d");
echo $firstWeek." - ";
echo $endWeek;

$nextweek = date(("Y-m-d"), strtotime("+7 Days"));
$week1 = date('w', strtotime($nextweek));
$date1 = new DateTime($nextweek);
$firstWeek1 = $date1->modify("-".$week1." day")->format("M d");
$endWeek1 = $date1->modify("+6 day")->format("M d");
echo $firstWeek1." - ";
echo $endWeek1;

 

I have range of categories from 1 to 999

With this is piece of code:

foreach (range(96,204) as $number)
if (Tools::getValue('id_category') == $number)
return;
$this->filterResults();
return $this->display( __FILE__, 'block-center-filter.tpl');

iw managed to avoid display of 'block-center-filter.tpl' in that range but it shows in every other categories.

What i need is opposite... i would like to dont show except in that range...
how to do that?

This works if say I do 192.168.0.1 - 192.168.1.254 it will work. However doing 192.168.0.1 - 192.168.1.10 will only generate up to .10 on both IP schemes. I see why, but I cannot figure out a way around this...

Thanks!

$start = explode('.', '192.168.10.1');
$end = explode('.', '192.168.11.10');

/**
 * Final output...
 */
$a = 0;
$b = 0;
$c = 0;
$d = 0;

// First segment
for ($a = $start[0]; $a < 1 + $end[0]; $a++)
{
// Second segment
for ($b = $start[1]; $b < 1 + $end[1]; $b++)
{
// Third segment
for ($c = $start[2]; $c < 1 + $end[2]; $c++)
{
// Fourth segment
for ($d = $start[3]; $d < 1 + $end[3]; $d++)
{
echo "{$a}.{$b}.{$c}.{$d}<br />";
}
}
}
}

Hi,

I am trying to come up with the best way to create a range voting form.
Each candidate will have a "confidence" value associated with the choice.(using a pulldown menu?)
So for March Madness it would be:
Team .......
Confidence Value.....

each team could only be voted to finish the tournament in a particular place, and a value would be associated with that choice. The total choices possible determines the range of confidence value possible.
So....if there are 16 teams to vote on....the confidence value would range from 1-16. The voter would assign his highest available value to the team he was most confident in landing in that particular position.
Example: 16 teams - 16 conf vals -

if certain Duke will end up at #1 - then vote :
#1 = Duke, conf val 16

next, if almost as certain that NC will end up last - then vote:
#16 = NC, conf val 15

next most certain
"", conf val 14
and so on....

the tricky part is making sure that the form code validates each conf val so that it is used, but used on ly once....

ideally the form could return values that could then be imported into excel and comopared.


has this been done somewhere?
