How can I return a value without breaking a loop

Question

How can I return a value without breaking a loop, The purpose of this is to return the increment value of a for loop to represent "attempts" that I want to return to view, for example read JSON that takes attempts I want to display it visually in view.

Example of what I've tried

for($i =0; $i< 15; $i++){
    numOfAttempts($i);
     try{
         file_get_contents('url')
     }catch(){}
}

public function numOfAttempts($i){return $i;}   //Return the attempt count to view

It's not entirely clear to me what you want. The `for` loop will not be broken since the `return` is performed inside another function. — Willem Van Onsem, May 01 '16 at 16:29
Yes I know it breaks, I want to display the $i variable live in view when its attempting to read file_get_contents. — Eric, May 01 '16 at 16:40

you can't do this in raw PHP. It's a server-side process. It starts, does it's work, ends. Results are sent to a browser. look here for work-arounds:

and here

also php is a single thread, you can emulate multithreading though. google php multithreading or look at http://robo.li

though, you CAN for, example, read a part of file (or try an url) then report back to user, then go for another run, but it will be not a parallel process, you'll need to place your display inside your loop
