Question

Let’s say I’ve a code:

foreach($array as $key => $value)
{
    //do something
    if($var === true) //"reverse"
}

is it possible to “reverse” foreach, so it’ll “run” with the same array’s element it was “running” when called to “get back” ;)?

Answer 1

You will have to use a normal for loop and make the last parameter (the modifying part) depend on a variable.
