How do I repeat a function (x times, each time unique output)?
<p>I'm trying to create an app that will repeat a function X number of times. Each time, the function will generate a random number. Once it generates the code, the code would then create an array with the new random numbers. Any help would be appreciated.</p>

<p>I have the code that create the random number and hyphenates it, but I'm having trouble calling the function cardNumber to repeat itself x number of times and put the results in an array.</p>

<pre><code>function hyphenate($str) {
return implode("-", str_split($str, 4));
}

function cardNumber() { 
for ($s = '', $i = 0, $z = strlen($a = 'ABCDEFGHJKLMNOPQRSTUVWXYZ')-1; $i != 2; $x =      rand(0,$z), $s .= $a{$x}, $i++);

$uid = uniqid(true);
$ccn = substr_replace($uid, $s, 0, 0);
$upperccn = strtoupper($ccn);
$editedccn = hyphenate($upperccn);
return $editedccn;
};

$array = array(str_repeat(cardNumber(), 2));
var_dump ($array);
</code></pre>
