Wondered about the different results between the crc32() and hash() functions, even when the
different return types were taken into account between the two functions.
<?php
echo dechex(crc32('12345')) . "\n";
echo hash('crc32', '12345') . "\n";
echo hash('crc32b', '12345');
?>
->
cbf53a1c
b8486542
cbf53a1c
From additional verification
e.g. http://rogeriopvl.com/hashr/
PHP's crc32() function is calculating the crc32b checksum.
Perhaps this might be useful for clarification.
