Question

I am trying to use a regular expression to replace any domain in a string with another domain but it isn’t working yet.

I tested the RegEx part on regexpal.com and it seems to be working.

Here is my code:

$itemdesc = str_replace("([a-z0-9\-]+).(com|net|org|co|cm|info|cc)\s\i","Example.com",$itemdesc);

Please Help! Thanks in advance

Answer 1

You need delimiters and preg_replace:

$itemdesc = preg_replace("/([a-z0-9\-]+)\.(com|net|org|co|cm|info|cc)/si","Example.com",$itemdesc);

Note the slashes at either end – the modifiers following the last delimiter

Also note, the delimiters can be any character – try to use a character that isn’t used in your regular expression, otherwise it’ll need to be escaped everywhere.
