"Reference of a $value and the last array element remain even after the foreach loop. * two():- This function takes an array as argument ($arr).- The array function argument itself isn't passed by reference, so the function knows it isn't allowed to modify the original at all.- Then the foreach loop happens.

It is recommended to destroy it by unset()."I cannot stress this point of the documentation enough! It's called "copy-on-write" and means that PHP doesn't make any copies unless you try to MODIFY the value.- If you try to MODIFY $val, THEN it will allocate a NEW zval in memory and store $val there instead (but it still won't modify the original array, so you can rest assured). The array itself wasn't passed by reference to the function, so PHP knows that it isn't allowed to modify the outside array.- But it also sees that you want to look at all VALUES by reference (&$val), so PHP says "Uh oh, this is dangerous.

They don't need to be stored in memory when foreach starts.

Consider the array that contains some values (I called it $all Values in the example below) and we want to have only some of them (eg. I create an object that would serve as dynamic array, that means it would "dynamically update" its values together with $all Values.

So instead, just loop normally and trust the fact that PHP *is* actually smart enough to never copy your original array's values!

PHP uses "copy-on-write", which means that attempting to assign something new to $val is the ONLY thing that causes a copying, and only of that SINGLE element!

This will assign reference instead of copying the value."There are cases where array_walk or array_map are inadequate (conditional required) or you're just too lazy to write a function and pass values to it for use with array_map...If the key is on the other hand a string that can be type-juggled into a float, it will stay a string.(Observed on PHP 7.0.0RC8) I want just to mention that John is not entirely true.foreach has some side effects on the array pointer.Don't rely on the array pointer during or after the foreach without resetting it."Is this no longer the case?
