PHP - assigning function return to variable
<p>I have a PHP script that returns a random password.  How do I echo out the password that is generated?</p>

<pre><code>&lt;?php

function generatePassword($length=9, $strength=0) {
    $vowels = 'aeuy';
    $consonants = 'bdghjmnpqrstvz';
    if ($strength &amp; 1) {
        $consonants .= 'BDGHJLMNPQRSTVWXZ';
    }
    if ($strength &amp; 2) {
        $vowels .= "AEUY";
    }
    if ($strength &amp; 4) {
        $consonants .= '23456789';
    }
    if ($strength &amp; 8) {
        $consonants .= '@#$%';
    }

    $password = '';
    $alt = time() % 2;
    for ($i = 0; $i &lt; $length; $i++) {
        if ($alt == 1) {
            $password .= $consonants[(rand() % strlen($consonants))];
            $alt = 0;
        } else {
            $password .= $vowels[(rand() % strlen($vowels))];
            $alt = 1;
        }
    }
    return $password;
}
