string::crc32 Compute CRC32 of a String
string::crc32(string [, error: variable, return_int: bool, string...])
Aliases: crc32
The crc32 function calculates the CRC32 checksum for a given string and returns the result.
By default, the return value is a hexadecimal string. If the return_int parameter is set to true, the function returns the checksum as an integer.
string
The string or strings for which the CRC32 checksum will be computed.
error (optional)
A variable to capture any error information.
return_int (optional, boolean)
If set to true, the function returns the CRC32 checksum as an integer instead of a hexadecimal string.
