Question

preg_match returns only the first result.
lets say I have the string abcabcabc and I wanna find ALL indexes of ABC. (ofcourse mine is a bit more complex…) – how can I do it ?
Thank you!

Answer 1

preg_match_all

You simply have to pass in a variable as the third argument that will be loaded up with all your matches.

Example

<?php
$pattern = "/{[^}]*}/";
$subject = "{token1} foo {token2} bar";
preg_match_all($pattern, $subject, $matches);
print_r($matches);
?>

output:

Array
(
    [0] => Array
        (
            [0] => {token1}
            [1] => {token2}
        )

)
