Call PHP function from url?

Question

If I want to execute a php script, i just point the browser to www.something.com/myscript.php

But if i want to execute a specific function inside

Answer 1

One quick way is to do things like

something.com/myscript.php?f=your_function_name

then in myscript.php

if(function_exists($_GET['f'])) {
   $_GET['f']();
}

But please, for the love of all kittens, don't abuse this.
