I am ASP.NET developer learning PHP on my own. But I am not able to find expression validator or compare expression validator which used to compare two properties filled in text boxes. It will be good if someone could help me with this

Do you mean regular expressions? There is the preg_match() function. Make sure you search for what you are looking for as well. The search terms I used here were: PHP regular expressions.
