Another did you know in PHP.

< ?
function test() {
echo "This function can be called dynamically!";
}
$function_name = "test";
$function_name();
?>

What is the output of the code show above? If you guessed that the output is “This function can be called dynamically!”, you may be a PHP guru.

The code shows you how to dynamically call the function test without actually calling test(). This method of calling a function could be useful in complex applications where you have to call on a function dynamically from you code.

Here’s a tutorial which shows you how to use :

• Dynamic Vairables
• Dynamic functions and objects
• Dynamic static properties and methods

When you’re trying to build more complex classes/applications, the need for doing things dynamically often arises. I figured I’d compile a list of ways to do dynamic PHP for those starting out with PHP. Please note that the list was elaborated with PHP 5 in mind.
