Result: Discarded
The test labeled "create_function()" was the faster by 0.0914 seconds, (17.565% faster)
The create_function() test took 0.4291 seconds.
The eval() test took 0.5205 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 112,327 loops for a total of 2,246,540 runs.
- Line execution difference (0.000041) milliseconds.
- Avg difference (4.571) milliseconds per 112,327 loops.
- Total difference 91.43 milliseconds for 2,246,540 loops
The iteration variablity for Code 1 was (8.6938) milliseconds and Code 2 was (3.0807) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "eval()", was:
eval(' $x = 0; $x += 5; if ($x >= 5) $x = 0; $x; $x;');
The second test, "create_function()", was:
$GLOBALS['dummy'] = create_function('', ' $x = 0; $x += 5; if ($x >= 5) $x = 0; $x; $x;'); $GLOBALS['dummy']();
