uniqid

Duplication of uniqid in PHP with high concurrency The most recent project has been useful to generate token validation issues. First consider using PHP's uniqid () function to generate a random string, but since the function seems to be based on

The problem with generating token checksums is useful in recent projects. First consider using the Uniqid () function in PHP to generate random strings, but because the function seems to be based on the microsecond time level. In the case of high

The Uniqid () function generates a unique ID based on the current time in microseconds.GrammarUniqid (prefix,more_entropy)Parameter descriptionprefix is optional. Specify a prefix for the ID. This parameter is useful if two scripts generate IDs

     $str = uniqid(mt_rand(),1);     echo ‘sha1: ‘,sha1($str);     echo ‘‘;     echo‘MD5:　‘,md5($str);Using the Uniqid function, with the Mt_rand random function, the last hash is worth the final unique value.But in the test, the uniqueness of the

UNIQID+MD5 basically no duplicate ID in high concurrency $units = Array (); for ($i =0; $i $units []=md5 (Uniqid (MD5 (Microtime (TRUE)), true); } $values = Array_count_values ($units); $duplicates = []; foreach ($values as $k = =

Method One: ?     PHP $str = uniqid (Mt_rand (), 1); Echo ' SHA1: ', SHA1 ($STR); Echo ' '; Echo ' MD5: ', MD5 ($STR); Using Uniqid function, with Mt_rand random function, finally using hash is worth the final unique value. But in the test, the

There is a button on the interface, click to send an AJAX request to the background, the requested file content: redis.php: ini_set('default_socket_timeout',25);$redis = new Redis();$conn = $redis->connect('127.0.0.1','6379');if($conn){

$ _ SESSION [& #39; uniqid & #39;] $ _ uniqidsha1 (uniqid (rand (), true); this $ _ SESSION [& #39; isn't uniqid & #39;] and $ _ uniqid necessarily equal .. Why can I check whether the value of $ _ SESSION [& #39; uniqid & #39;] is the same as that
