Return a loop in function php

Question

Is it possible to return a loop? not the result but the loop it self. I want to create a function in php. For example like this.

function myloop($sql){
$quer         


        

Answer 1

You should turn it inside out!

Instead of returning the loop, you could do it this way using Variable functions :

function myloop($sql, $myFunction){ 
    $query = mysql_query($sql);  
    while(mysql_fetch_assoc($query)) {
        $myFunction($result);
    }

} 


function doSomethingWithTheResult($result) {
   echo $result; // just to have something here...
}

//now the usage:
myloop("SELECT 1", 'doSomethingWithTheResult');

With a squint, this is similar to the concept of the Template method OOP design pattern.
