The following code:

1 <?php
2 xdebug_start_code_coverage(XDEBUG_CC_UNUSED|XDEBUG_CC_DEAD_CODE);
3 function a() {
4 return NULL;
5 $c = 1;
6 }
7 $z = 5;
8 if($z == 5) {
9 $c = 3;
10 } else {
11 $c = 5;
12 }
13 a();
14 $cc = xdebug_get_code_coverage();
15 xdebug_stop_code_coverage();
16 var_dump($cc);
17 ?>

prints out:
