PHP crc32() Function
crc32() function generates the cyclic redundancy checksum (CRC) polynomial of 32-bit lengths of the given string.
This function is usually used to validate the integrity of data being transmitted.
Note: This function may return negative integers on 32bit platforms as PHP's integer type is signed. So you need to use the "%u" formatter of sprintf() or printf() to convert the
crc32() result to an unsigned integer.
|str||Required||Specifies a string to generate a 32-bit cyclic redundancy code (CRC).|
|Integer||Returns the crc32 checksum of the given string.|
