Question

I’ve been wondering whether it is possible or not to pass a function as a parameter in PHP. I want something similar to when you’re programming the following code in JavaScript:

object.exampleMethod(function(){
    // some stuff to execute
});

What I want is to execute that function somewhere in exampleMethod. Is that possible in PHP?

Answer 1

It’s possible if you are using PHP 5.3.0 or higher.

See Anonymous Functions in the manual.

In your case, you would define exampleMethod like this:

function exampleMethod($anonFunc) {
    //execute anonymous function
    $anonFunc();
}
