Warning: preg_replace(): Unknown modifier '('

[terungwa]

$text = preg_replace("/([^[])/me([^\n\r$]*)([\n\r$])/", "\\1<span class=\"me\">*".$ubbObj->username." \\2 *</span>\\3", $text); 
  $text = nl2br($text);

$text = preg_replace("([^[])/me([^\n\r$]*)([\n\r$])", "\\1[me=".$this->username."]\\2[/me]\\3", $text);

I was editing the code bit above (converting eregi_replace to preg_replace) but i am getting a warning: Warning: preg_replace(): Unknown modifier '('

could you help me resolve the right regex synthax.

 

Thanks.

If you use / delimiters then you have to make sure you escape them inside the expression (or not even use them at all).

 

~ and # are common alternatives.

"#([^[])/me([^\n\r$]*)([\n\r$])#"
