searching array

[tonax99]

Hi, I'm trying to figure out a way to search my array for any instance of 'images/smilies/' and remove that key from the array. I tried using search_array but it seems it only looks for exact matches, which wont work because the key will have 'images/smilies/rofl.gif' for example.

 

here's an example of my array output. it's a multidimensional array so these are the results of my print_r (imgmatches[1]);

 

Array
(
    [0] => http://i25.photobucket.com/albums/c62/becominglucid/Snapshot_20090529.jpg
)
<br>Array
(
    [0] => images/smilies/frown.gif
)
<br>Array
(
    [0] => http://i25.photobucket.com/albums/c62/becominglucid/Snapshot_20090529_7.jpg
    [1] => images/smilies/frown.gif
)

 

it seems so simple but my knowledge is pretty limited

Try this:

 

<?php
$arr = Array("images/smilies/rofl.gif", "don't remove", Array("images/smilies/something.gif", "don't remove", "don't remove"));

function removeRec(&$arr)
{
foreach($arr as $key => &$part)
{
	if(is_array($part))
		removeRec($part);
	else if(!stristr($part, "images/smilies") === false)
		unset($arr[$key]);
}
}
echo "<pre>";
print_r($arr);
removeRec($arr);
print_r($arr);
echo "</pre>";
?>

 

Output:

 

Array
(
    [0] => images/smilies/rofl.gif
    [1] => don't remove
    [2] => Array
        (
            [0] => images/smilies/something.gif
            [1] => don't remove
            [2] => don't remove
        )

)

Array
(
    [1] => don't remove
    [2] => Array
        (
            [1] => don't remove
            [2] => don't remove
        )

)
