How can I remove all matched parts from string?

Question

Here is my code:

$tags_specified_pattern = "/\[(.+?)\]/";
preg_match_all($tags_specified_pattern, $q, $matches);
if ( count($matches[1]) ){
    I need to remove all matched parts form $q
}

Here is an example:

$q = "This is [tag1] tag1 and this is [tag2] tag2";

And this is the expected result:

This is tag1 and this is tag2

Any idea how can I do that?

So, `$q = preg_replace($tags_specified_pattern, '$1', $q);`, what is the problem? — Wiktor Stribiżew, Jun 21 '18 at 11:20
@WiktorStribiżew The problem is `preg_mach` has an `all` version. `preg_match_all`. But `preg_replace` hasn't. — Martin AJ, Jun 21 '18 at 11:25
@MartinAJ `preg_replace` replaces all match occurrences by default. — Wiktor Stribiżew, Jun 21 '18 at 11:26

You can use preg_replace

<?php
$pattern = '/\\[(.+?)\\]/';
$replacement = '';
$subject = 'This is [tag1] tag1 and this is [tag2] tag2';
echo preg_replace($pattern, $replacement, $subject, -1 );
?>

The maximum possible replacements for each pattern in each subject string. Defaults to -1. – Bhumi Shah Jun 21 '18 at 11:26
