crc32 hash

The crc32 function of php must be used with caution (otherwise it is a pitfall. The crc32 function of php needs to be used with attention (otherwise it is a pitfall). The crc32 function has written a table sharding program a few days ago. the hash

PHP Crc32 function to be aware of the problem (or pit), CRC32 function A few days ago wrote a sub-table program, using the hash algorithm is CRC32. The functions of the table are as follows:Copy the Code code as follows:function _gethash ($username)

What kind of pits does PHP crc32 encounter? How do I fix it? This paper mainly introduces the problems needing attention when using PHP's CRC32 function. Hope to use CRC32 to help you. A few days ago wrote a sub-table program, using the hash
