I know you are trying to generate your password in a specific way, but you might want to look at this method as well...

<pre><code>$bytes = openssl_random_pseudo_bytes(2);

$pwd = bin2hex($bytes);
</code></pre>

It's taken from the php.net site and it creates a string which is twice the length of the number you put in the openssl_random_pseudo_bytes function. So the above would create a password 4 characters long.

In short...

<pre><code>$pwd = bin2hex(openssl_random_pseudo_bytes(4));
</code></pre>

Would create a password 8 characters long.

Note however that the password only contains numbers 0-9 and small cap letters a-f!

You want <code>strlen($alphabet)</code>, not <code>count</code> of the constant <code>alphabet</code> (equivalent to <code>'alphabet'</code>).

However, <code>rand</code> is not a suitable random function for this purpose. Its output can easily be predicted as it is implicitly seeded with the current time. Additionally, <code>rand</code> is not cryptographically secure; it is therefore relatively easy to determine its internal state from output.

Instead, read from <code>/dev/urandom</code> to get cryptographically random data.

My answer is similar to some of the above, but I removed vowels, numbers 1 and 0, letters i,j, I, l, O,o, Q, q, X,x,Y,y,W,w. The reason is: the first ones are easy to mix up (like l and 1, depending on the font) and the rest (starting with Q) is because they don't exist in my language, so they might be a bit odd for super-end users. The string of characters is still long enough. Also, I know it would be ideal to use some special signs, but they also don't get along with some end-users.

It ensures that password has numbers, upper and lower case letters as well as a minimum of 3 special characters.

Length of the password will be between 11 and 30.

 $special = array_rand(array_flip(['@', '#', '$', '!', '%', '*', '?', '&amp;']), rand(3, 5));

 $password = array_merge(
 $numbers,
 $uppercase,
 $lowercase,
 $special
 );

 shuffle($password);

 return implode($password);
