Q. How do I delete an element from a PHP array?
A. You can unset($a[$element]) but that leaves a hole so the only way is
to copy the array to a new one without the unwanted element.
I think this is an unfortunate limitation for a high level language.
Even C++'s vector can erase() elements.
The only exceptions are:
array_shift() Remove the first array element
array_pop() Remove the last array element
