// Example usage of the build-in array slice method:
 
$ExampleArray = array(1, 2, 3, 4, 5, 6);
 
$ResultArray = array_slice($array, 0, 4);
 
print_r($ResultArray);
 
/*
 
Returns: 
    array(1, 2, 3, 4)
 
*/
 
 
/*
** My old method (deprecated)
**
** I created this method before I found the array_slice method.
*/
function ArrayLimit($InputArray, $From, $Length=0){
 
    $NewArray = array();
    $Length = ($Length==0) ? count($InputArray) - $From : $Length;
    $c = 0;
 
    reset($InputArray);
    while(list($k,$v) = each($InputArray)){
 
        if ($c >= $From && $c < $Length)
            $NewArray[$k] = $v;
        else 
            break; 
 
        $c++;
    }
 
    return $NewArray;
}
