How to create my own function with { } in PHP

Question

I want to create my own function loop():

loop($x,$y){
    //do something
}

it should work like for, foreach operators:

$y=count($array); 
for($x=0; $x<$y; $x++){ 
     //do something 
}

How to create functions like this with { } in PHP? (NOT a regular function)

Answer 1

You can't.

Constructs like for or foreach are part of php syntax.

If you want to create regular function just use function keyword:

function some_func($x, $y)
{
....
}

Answer 2

There will be lambda functions - that's what you want to do - in PHP 6. Right now you have to stick with "normal" functions.

Answer 3

At a more advanced level, you could create a class and iterate that, in which you can pretty much change the execution flow during execution (while iterating).

Here's the docs: http://php.net/iterator

Answer 4
