Trimming Whitespace

Just a very small function for you, if you wish to replace spaces in a variable, use this function. The good this about it is that it does not matter how much whitespace there is, it will convert it to an _

PHP Code:


		
			
function removeSpace($input){
    echo preg_replace("/(\s)+/", "_", $input);
}

The underlines remind me of some MOD_REWRITE urls. Haha

e.g. HTTP://WWW.EXAMPLE.COM/BLOG/MY_FIRST_ENTRY/

Depends on what result you prefer. The original method will take any amount of spaces in a row and replace them with a single underscore. The second method would return one underscore for every space it found.
