CRC32
Calculates the crc32 polynomial of a string
SYNTAX
crc32 ( string $str ) : int
PARAMETERS
str
The data.
RETURN
Returns the crc32 checksum of str as an integer.
Warning: Because PHP's integer type is signed many crc32 checksums will result in negative integers on 32bit platforms. On 64bit installations all crc32() results will be positive integers. Use the "%u" formatter of sprintf() or printf() to get the string representation of the unsigned crc32() checksum in decimal format.
