Re: How to force an associative array

It looks like you have not declared and intialized $_k before using it > if (($_pos = stripos($_the_header,$_head_reqd[$_k])) !== false) 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 > On Jan 22, 2023, at 2:20 PM, John Iliffe <john.iliffe@iliffe.ca> wrote: > > I have an application where the members (by name) of an associative array are > not known until run time.
