xdebug_start_code_coverage( XDEBUG_CC_UNUSED | XDEBUG_CC_DEAD_CODE );

function a($a) {
     echo $a * 2.5;//non eseguita
}

function b($count) {
     for ($i = 0; $i < $count; $i++) {
         a($i + 0.17);
     }
}

b(10);

print_r(xdebug_get_code_coverage());

Si ottiene

Array
         (
             [4] => 1
             [5] => 1
             [6] => 1
             [8] => 1
             [9] => 1
             [10] => 1
             [12] => 1
             [14] => 1
             [16] => 1
         )

Ma perchè viene indicato ***[5] => 1*** che anche la riga 5 viene eseguita?
