preg_replace

[poe]

how do i do a replace all occurances of 'w-l' to 'wlt'

preg_replace("w-l","wlt",$cleanData);

i get this error:
Delimiter must not be alphanumeric or backslash

[c4onastick]

Regular expressions require delimiters to tell it where the pattern starts and ends.
[code]$cleanData = preg_replace('/w-l/', 'wlt', $cleanData);[/code]
This tells the regex engine that the pattern is between the '/' characters.
