[TYPO3-core] RFC #9994: Bug: ereg_replace is deprecated in PHP 5.3 alpha3

[Steffen Kamper]

Hi,

i broke it down.

Error happens in class.t3lib_syntaxhl.php line 383

This was the line before:
$markUpStr = ereg_replace('<([[:alnum:]_]+)[^>]*>',$token.'\1'.$token,$str);

was replaced by:
$markUpStr = 
preg_replace('/<([[:alnum:]_]+)[^>]*>/',$token.'\1'.$token,$str); 
(doesn't work)

I found this as working alternative:
$markUpStr = 
preg_replace('/<([[:alnum:]_]+)[^>]*>/',"$token\\1$token",$str);

Alternative:
$markUpStr = preg_replace('/<([\w]+)[^>]*>/', "$token\\1$token", $str);

i'm not 100% sure if \w has too much in opposite of [:alnum:]_
