Regular expression - starting and ending with a character string

Question

I would like to write a regular expression that starts with the string \"wp\" and ends with the string \"php\" to locate a file in a directory. How do I do it?

Answer 1

^wp.*\.php$ Should do the trick.

The .* means "any character, repeated 0 or more times". The next . is escaped because it's a special character, and you want a literal period (".php"). Don't forget that if you're typing this in as a literal string in something like C#, Java, etc., you need to escape the backslash because it's a special character in many literal strings.
