Question

i couldnt find the idea to do what i want

so i decided to ask my question here 🙂

i want select numbers of groups from text with preg_match_all

(itemgroup (index 24813) (group (200 24813)))
(itemgroup (index 2481) (group (50 2461)(100 2471)(150 2491)))

i want the output to be like that

index 24813 => 24813

index 2481 => 2461 / 2471 / 2491

is there any idea how to do it with preg_match_all

Thank You

Try with this code:

<?php
$string = '
(itemgroup (index 24813) (group (200 24813)))
(itemgroup (index 2481) (group (50 2461)(100 2471)(150 2491)))
';

preg_match_all('#\(itemgroup \(index ([0-9]+)\) \(group ([0-9()\s]+)\)\n*#', $string, $match);
$index = $match[1];
$groups = $match[2];
for ($i = 0; $i < count($index); ++$i) {
    preg_match_all('#\([0-9]+ ([0-9]+)\)#', $groups[$i], $group);
    $group = implode(' / ', $group[1]);
    echo 'index ' . $index[$i] . ' => ' . $group . "\n";
}
