On: How PHP's foreach works

[narcissus]

I hear ya. In fact, I got burned by that problem enough times to make a test for it in my PHPCS 'coding standard'... which is basically a handful of standards that look for my stupid, repeated, coding errors :)

[function_seven → narcissus]

My own standard is this:

    foreach ($array as & $ref) {
        // Do something with $ref
    } unset ($ref);

i.e. put the `unset()` call on the same line as the closing brace, forever "welding" it to that block.
