How can I use a PHP function inside of another function?
<p>I need to use a function inside of another function, how can I do this?  I realize that the function is out of the scope,  I do not understand OOP and classes yet.  can someone help me?  </p>

<pre><code>function some_function ($dfd, $characters, $dssdf, $sdfds){

    $sdfs = 'sdfsdf'; //random stuff goes on

    //this is where my trouble begins I have a scope issue, I need to call this function inside of this function
    readable_random_string($characters);
}
</code></pre>

<p><strong>UPDATE here is the other function as requested</strong>  </p>

<pre><code>function readable_random_string($length = 6) {
    $conso = array("b", "c", "d", "f", "g", "h", "j", "k", "l", "m", "n", "p", "r",
     "s", "t", "v", "w", "x", "y", "z");
    $vocal = array("a", "e", "i", "o", "u");
    $password = "";
    srand((double)microtime() * 1000000);
    $max = $length / 2;
    for ($i = 1; $i &lt;= $max; $i++) {
     $password .= $conso[rand(0, 19)];
     $password .= $vocal[rand(0, 4)];
    }
    return $password;
}
</code></pre>
