kurtubba's code was helpful, but didn't quite work for me.
Here's my version in case anyone has the same issue:
<?php
function UniqueRands($min, $max, $keys){
    static $retval = array();

    $x = rand($min,$max);

    if(!in_array($x,$retval)){
        array_push($retval, $x);
    }
    if($keys > count($retval)){
        UniqueRands($min, $max, $keys);
    }
    return $retval;
}

$var = UniqueRands(1, 4, 4);
print_r($var);

?>

Bear in mind I'm not the best with php! But my version worked for me at least.
