Result: Discarded
The test labeled "eval()" was the faster by 0.0224 seconds, (5.203% faster)
The eval() test took 0.4077 seconds.
The create_function() test took 0.4301 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 115,236 loops for a total of 2,304,720 runs.
- Line execution difference (0.000010) milliseconds.
- Avg difference (1.119) milliseconds per 115,236 loops.
- Total difference 22.37 milliseconds for 2,304,720 loops
The iteration variablity for Code 1 was (0.7626) milliseconds and Code 2 was (1.9487) 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']();
