preg_replace(): The /e modifer is deprecated, use preg_replace_callback instead php

Question

Error:

preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead

Code:

function convert_url_to_bbcode($messagetext){
$skiptaglist = 'url|email|code|php|html|noparse';

return preg_replace(
    '#(^|\[/(' . $skiptaglist . ')\])(.*(\[(' . $skiptaglist . ')|$))#siUe',
    "convert_url_to_bbcode_callback('\\3', '\\1')",
    $messagetext
); }

Any ideas? By the way, I have 0 php experience. Sorry :)

Answer 1

The message is self explanatory, use preg_replace_callback and pass the code as anonymous function instead of putting the code in the regexp string:

return preg_replace(
    '#(^|\[/(' . $skiptaglist . ')\])(.*(\[(' . $skiptaglist . ')|$))#siU',
    function ($ match) { return convert_url_to_bbcode_callback($m[3], $m[1]); },
    $messagetext
);
