Question

I have those tags in a text pulled from database
[ATTACH=CONFIG]9[/ATTACH] and I am trying to extract the number, 9 in that case.

My first try

$images = preg_match_all(#\[ATTACH.*?\[/ATTACH\]#si, $article['pagetext'], $images['matches']);
    $image = $images['matches'][1][0];

is not returning anything.

Can someone please help me with proper regex? thank you.

I have tested the following code with php5.4.5:

    <?php
$article = array();
$article['pagetext'] = '[ATTACH=CONFIG]9[/ATTACH][ATTACH=CONFIG]10[/ATTACH]';
$images = array();
$images['matches'] = array();
if(preg_match_all('/[ATTACH[^\]]*\](\d+)\[\/ATTACH\]/i', $article['pagetext'], $images['matches']) > 0){
    # will print out "9", "10"
    for($i = 0; $i < count($images['matches'][1]); ++$i)
        printf("%s\n", $images['matches'][1][$i]);
}
