However, I'd be pretty surprised if you've actually run into a bug in PHP--I would first suspect a bug in your code. No offense intended--that's just how it usually plays out. :) What it looks like to me is that something is causing $foo to be a string before the '$foo[] = "bar";' line is encountered. What do you get if you put a gettype($foo); just before that line? > $foo=null; > $foo[]="bar"; // <-- $foo simply becomes an array > > The problem is not limited to one place in code, and indeed before the fatal > caused by append-assignment I get several warnings like "array_diff_key(): > Argument #1 is not an array", where the offending argument receives a result of > array(). This would appear to support my suspicion, but try inserting the gettype($foo) (or better, var_export($foo);) just before one of the lines which triggers the error, and post the results. Can you post the code in a .zip file or online somewhere? If not, that's cool, but it will probably make it harder to help you track it down if you can't.
