Get the Current URL of Page with PHP

The URL shortening service TinyURL.com provides an API for programmatically processing URL shortening requests through your own script.

It’s actually pretty easy.

function short($url) {
    return file_get_contents("http://tinyurl.com/api-create.php?url=".$url);
}

Alternatively, you can use [cURL to download remote URLs contents](http://ephp.info/php-curl-download-url "Download Remote File Using CURL and PHP") if your server doesn’t support file\_get\_contents.

Getting the thumbnail of a Youtube video through it’s ID is not that hard. You just have to transform the URL a little bit to get a high quality JPG file, used as a main thumbnail through Youtube.com.  
\[ad name=”In Post”\]  
All Youtube videos have their own unique ID which is 11 charcaters long. A typical Youtube video URL will look like this:

`http://www.youtube.com/watch?v=**i3_dOWYHS7I**`

The part in bold is the part you are interested in. You can get it by using a simple [explode()](http://php.net/explode) function.

After you get the ID you just need to point an image to the following URL structure:

`http://i2.ytimg.com/vi/**i3_dOWYHS7I**/0.jpg`

Where the part in bold should be replaced with the specific video ID.

Using the above video as example will return this image:  
![](http://i2.ytimg.com/vi/i3_dOWYHS7I/0.jpg)

If you want to save it to your server and not hotlink the Youtube servers you can use something like [cURL](http://ephp.info/php-curl-download-url "Download Remote File Using CURL and PHP") or file\_get\_contents.

This is a simple tip but most experienced PHP programmers don’t know that it even exists.  
If you want to have a bunch of variables contain the same value, your common sense will tell you to do this:

$var1 = "text";
$var2 = "text";
$var3 = "text";

What if I told you there was an easier way? In fact, a way which works in most programming languages. There it is:

$var1 = $var2 = $var3 = "text";

Now you know how to save some time.
