Re: How to force an associative array

It looks like you have not declared and intialized $_k before using it

I believe you should declair it and initialize it in a higher scope like so:

$_k = 0;
> if (($_pos = stripos($_the_header,$_head_reqd[$_k])) !== false)

You are also not incrementing $_k that I can see
