code below gives a deprecation warning after upgrading to PHP 5.5+

$sentence=preg_replace('/~([^<>]{1,})~/e', "'<span class=\"helpstart\">'.UTF8_strtoupper('\\1').'</span>'", $sentence);

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

How can I replace the code with preg_replace_callback()?

  • The documentation is pretty clear, you just return the value you would want the match to be replaced with in a callback function : http://in3.php.net/preg_replace_callback – DhruvPathak Jan 28 '14 at 10:17
  • OK, thanks for your suggestion – jones Jan 28 '14 at 10:42

$sentence=preg_replace('/~([^<>]{1,})~/', function($match) {return "<span class=\"helpstart\">".UTF8_strtoupper($match)."</span>"; } , $sentence);

as per http://www.php.net/manual/en/function.preg-replace-callback.php

$sentence=preg_replace_callback('/~([^<>]{1,})~/', function($match) {return "<span class=\"helpstart\">".UTF8_strtoupper($match[1])."</span>"; } , $sentence);

The first answer was an error on the function.
