I want to generate password randomly and send to mysql database using PHP..i have got the following function for generating password but doesn't know how to incorporate in my registration form and where to call that function and update password field in database..please help me..

Expand|Select|Wrap|Line Numbers

 
    function generatePassword ( $length = 8 ) {

    // start with a blank password

    $password = “”;
 
    // define possible characters

    $possible = “0123456789abcdefghijkmnpqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ!@#$%^&*”;
 
    // set up a counter

    $i = 0;
 
    // add random characters to $password until $length is reached

    while ($i < $length) {

    // pick a random character from the possible ones

    $char = substr($possible, mt_rand(0, strlen($possible)-1), 1);
 
    // we don’t want this character if it’s already in the password

    if (!strstr($password, $char)) {

    $password .= $char;

    $i++;

    }

    }

    // done!

    return $password;

    }

where should i call this function generatePassword????

Keep this function at the bottom of your PHP script, or in some other dedicated .php file for this function and include that PHP script in your present script.

Then use this function like

Expand|Select|Wrap|Line Numbers

 $new_password = generatePassword (10); //whatever length

$sql = mysql_query("INSERT INTO ..... .... (`password`, ... ... ...) VALUES ($new_password, ... ... ...)")

You could just use one of the built in random functions or hash functions.
