This function returns the unsigned crc32 value. I realized it's not very obvious from the
current documentation.
<?php
/**
* Function to compute the unsigned crc32 value.
* PHP crc32 function returns int which is signed, so in order to get the correct crc32 value
* we need to convert it to unsigned value.
*
* @param $str - String to compute the unsigned crc32 value.
* @return $var - Unsinged inter value.
*/
function computeUnsignedCRC32($str){
sscanf(crc32($str), "%u", $var);
return $var;
}
?>
