PHP generates a secure and random password program

php generates a random password, which is convenient and fast. It can randomly generate safe and reliable passwords. I hope this article will be helpful to everyone.

php generates a safe and random password program example code as follows:

header("Content-type:text/html;charset=utf-8");

function getRandPass($length = 6){

$password = '';

//Will Add the characters you want to the string below, the default is numbers 0-9 and 26 English letters

$chars = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";

$char_len = strlen( $chars);

for($i=0;$i<$length;$i++){

$loop = mt_rand(0, ($char_len-1));

//Treat this string as a Array, randomly pick out a character and loop it into the number of digits you need

$password .= $chars[$loop];

}

return $password;

}

echo getRandPass(12); //Randomly generate a 12-digit password

//Open source code phpfensi.com

?>

Example 2, a bit like the first one

1. Preset one The string $chars, including a – z, A – Z, 0 – 9, and some special characters

2. Randomly pick a character in the $chars string

3. Repeat the second step n times, you can get The example code for a password of length n is as follows:

function generate_password( $length = 8) {

// Password character set, you can add any characters you need

$chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRST UVWXYZ0123456789!@#$%^ &*()-_ []{}<>~`+=,.;:/?|';

​ $password = '';

for ( $i = 0; $i < $length; $i++ )

                                                                                                                                                                                                  . Any element of the array $chars

                                                                                                                                                                                                                                                   . $chars) - 1) ];

}

return $password;

}
