RE: Re[2]: [PHP] Searching for text in a file

Richard, I just put together a script using that code exactly, and it worked. All I can say is make sure that what you are searching for is actually in the file you are searching. Remember that the string you are searching for needs to match the entire contents of the line, not just a substring of the line. Try some simple tests that you know are sure to work. i.e. Make a virtusertable file that is just a couple of lines. > Hello Kelly, > Yes I noticed the variable after I sent the message > Now I have it like this.
