It is a headache to think about passwords one by one when creating a large number of users. Using php to randomly generate a secure and reliable password is convenient and fast, and you can add your own strings, you can use the FTP password, Mysql password, and website background password to implement code:
Header ("Content-type: text/html; charset = UTF-8 ");
Function getRandPass ($ length = 6 ){
$ Password = '';
// Add the desired character to the following string. The default value is 0-9 and 26 English letters.
$ Chars = "0123456789 abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ ";
$ Char_len = strlen ($ chars );
For ($ I = 0; $ I <$ length; $ I ++ ){
$ Loop = mt_rand (0, ($ char_len-1 ));
// Use this string as an array, randomly retrieve a character, and concatenate it into the desired number of digits.
$ Password. = $ chars [$ loop];
}
Return $ password;
}
Echo getRandPass (12); // generate a random 12-digit password
?>
