Result: Discarded
The test labeled "system()" was the faster by 0.1224 seconds, (16.023% faster)
The system() test took 0.6416 seconds.
The shell_exec() test took 0.764 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 133,939 loops for a total of 2,678,780 runs.
- Line execution difference (0.000046) milliseconds.
- Avg difference (6.121) milliseconds per 133,939 loops.
- Total difference 122.43 milliseconds for 2,678,780 loops
The iteration variablity for Code 1 was (5.1911) milliseconds and Code 2 was (6.6044) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "system()", was:
system('ls');
The second test, "shell_exec()", was:
echo shell_exec('ls');
