crc32
function call:
int crc32( string $str )
description:
Generates the cyclic redundancy checksum polynomial of 32-bit lengths of the $str. This is usually used to validate the integrity of data being transmitted.
Because PHP's integer type is signed, and many crc32 checksums will result in negative integers, you need to use the "%u" formatter of sprintf() or printf() to get the string representation of the unsigned crc32 checksum.
