And that's exactly what happens:

// $foo = 0;
[1] Evaluate 0 // result: 0
[2] Assign result of [1] to $foo // $foo = 0
// $foo = ($foo++);
[3] Evaluate operation "post-increment" on $foo // ($foo++)
[3.1] Set return value to current $foo // result: 0
[3.2] Add 1 to $foo // $foo = 1
[3.3] Return result // 0
[4] Assign result of [3] to $foo // $foo = 0

Thus, for a few nanoseconds, $foo is indeed 1, until this increment is
undone in [4] by reassigning $foo its old value.

No. That would be $a = ++$foo.

Greetings,
Thomas
