preg_replace problem

[JoeBrewer]

Hi

I have some text that I want to make sure that there is a space after each question mark. I am trying to use this code:

preg_replace( "\?[A-Z]", "\? \\2", "Is this a test?No." )

but I get this error message:

Warning: Delimiter must not be alphanumeric or backslash

Can someone tell me what I'm doing wrong please?

Thanks,
Joe

The error is because you need to have delimiters around your regex. Traditional is to use slashes. I noticed you didn't have parentesis around the character after the question mark as well. I've corrected it.

preg_replace( "/\\?([A-Z])/", "? \\\\1", "Is this a test?No." );

By the way, this only checks that the character after the question mark is not an upper case letter. If it were a number, lower case letter, etc, then this doesn't change it. Not necessarily a problem, just making sure you know. 🙂
