PHP Warnings

Posted by Anji (Anji), 23 August 2002
When submitting a form to append to a text file, I get the error, "WARNING: REG_EMPTY" and have been unable to find any mention of the meaning of this in PHP references.  Anybody any ideas?

Don't quote this as a definitive answer, but I'll have a go.

First off, did the error give you a line number? and if so did it happen to be near a regular expression?

I think whats happening is you've passed an empty string to ereg().

Back in a few minutes, I'll go and check...

yep, seems so.
I can replicate this error with the code below

Code:
<?php

if (ereg('', 'someText')) print "success";

?>


as you can see there is no regular expression in ereg (the regex should be the first argument) and it throws the error below.

: REG_EMPTY in /home/moylan/test.php on line 3

Have you mistyped a variable?

Do let me know what it was when you fix it though.

Thanks John, it was indeed a problem with an empty string being passed!
