PHP:

function encode36($x){
    return base_convert($x, 10, 36);
}
function decode36($x){
    return base_convert($x, 36, 10);
}

Actionscript 3:

function encode36(x:Number):String{
    return x.toString(36);
}
function decode36(x:String):int {
    return parseInt(x,36);
}

Edit: After searching a bit, I found another similar cURL solution that checks the actual headers. Since cURL can return HTTP code I don’t think all that extra code is necessary? I could be wrong!

function urlExists($url=NULL)
	{
		if($url == NULL) return false;
		$ch = curl_init($url);
		curl_setopt($ch, CURLOPT_TIMEOUT, 5);
		curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
		$data = curl_exec($ch);
		$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
		curl_close($ch);
		if($httpcode>=200 && $httpcode<300){
			return true;
		} else {
			return false;
		}
	}

SELECT * FROM `users` WHERE  DAYOFYEAR(curdate()) <= dayofyear(`bday`) AND DAYOFYEAR(curdate()) +7 >= dayofyear(`bday`) LIMIT 30;

There is of course one small problem with this, it’s not sorted. If we sort by `bday` ASC it’ll still be off since user’s are born on different years. What we really want is to sort by month and day only. I’m sure this can be done in MySQL but here is a PHP solution to take care of it.

$sql = "SELECT * FROM `users` WHERE  DAYOFYEAR(curdate()) <= dayofyear(`bday`) AND DAYOFYEAR(curdate()) +7 >= dayofyear(`bday`) LIMIT 30;";
$query = mysql_query($sql);
$rows = mysql_num_rows($query);
if(!empty($rows)){
	while($resultFind = mysql_fetch_array($query)){
		$arr[] = array('bday' => $resultFind['bday'], 'bday2' => date("md", strtotime($resultFind['bday'])));
	}
}

function compare($x, $y) {
	if ( $x["bday2"] == $y["bday2"] )
	 return 0;
	else if ( $x["bday2"] < $y["bday2"] )
	 return -1;
	else
	 return 1;
}

usort($arr, "compare");

Using usort() we can sort based on the month and day. You now have your list sorted

System.security.allowDomain("mydomain.com");

Add this to the Flash file you’re communicating with. Keep in mind that www.mydomain.com is different from mydomain.com to Flash.

images.wrichards.com CNAME images.wrichards.com.s3.amazonaws.com

Just add a CNAME record with that information and you should be good to go (obviously change my domain to yours). You can add your CNAME in your DNS entry More Info here. I can now access my bucket via the custom domain images.wrichards.com.The bucket name must match and be lowercase for this to work properly.

JQuery. Write less, do more

jQuery.fn.sort = function() {
   return this.pushStack( [].sort.apply( this, arguments ), []);
 };

function sortAlpha(a,b){
    return a.innerHTML > b.innerHTML ? 1 : -1;
};

$('ol li').sort(sortAlpha).appendTo('ol');

Short and sweet. The result is a in place sort based off the innerHTML alphabetically.

function isValidEmail($email){
 return filter_var(filter_var($email, FILTER_SANITIZE_EMAIL), FILTER_VALIDATE_EMAIL);
}

if(isValidEmail('email@domain.com')){
//valid
} else {
//not valid
}

I’ve been using PHP5 ever since it was released but didn’t look into the PECL Filter extension until recently. Pretty handy.

Please note that I also added the FILTER_SANITIZE_EMAIL filter which removes all illegal e-mail characters from a string. This is not needed if you only want to validate and not clean the input.

More on this with examples later.
