0's problem

-----------------------------------

when the user input "00" or "000" or "0000", ect..

convert to a string, check if every element in the string equals zero, then initialize to 0 and convert back to integer?

RE:0\'s problem

"00" _is_ a string. Simply typecast it into the integer.

Assuming you are trying to get rid of the leading zeros from a string.

I have no idea, my example was based on general programming.

Yes;  (integer) cast will also work, the intval() function may be worth looking into.  And sometimes there is is no need to cast at all as PHP is rife with type coercion.
$ php -r '$a = "12"; echo $a + 3 . "\n";'
15
