This article mainly introduces the speed test and comparison code for various encryption algorithms and Hash algorithms in PHP. for those who select an encryption algorithm, they can be considered as a performance factor, if you need it, you can refer to the PHP Hash algorithm which is usually used. Currently, MD5 is sometimes not safe, so you have to use other algorithms in Hash_algos (). The following is a performance comparison. Php code: define('testtime', 50000);$algos = hash_algos();fore
