Does it matter if I use the same variable names in different php files? Is this a bad practice or does this really not matter at all?

ok thanks for the clarification thats cool how strings and ints sort of intertwine, kind of mindblowing (i was expecting some ToInt() function similar to Koobi's suggestion) but i think i can get used to that

Does this function exist in PHP? I have been searching for this function for a while or any mention of it but have come up with nothing.  I'm using the $_GET['whatever'] to pass variables via the URL, and I am just not sure if that variable which is going to be a number needs to be converted to an integer if i want to use it to access part of an array. for example, could this hypothetically work? ($a is an array) $desc = $a[$_GET['whatever']]; I am assuming it will not, but my knowledge of php is very limited
