Result: Discarded
The test labeled "system()" was the faster by 0.0345 seconds, (2.703% faster)
The system() test took 1.2434 seconds.
The shell_exec() test took 1.2779 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 283,974 loops for a total of 5,679,480 runs.
- Line execution difference (0.000006) milliseconds.
- Avg difference (1.727) milliseconds per 283,974 loops.
- Total difference 34.54 milliseconds for 5,679,480 loops
The iteration variablity for Code 1 was (6.2731) milliseconds and Code 2 was (12.6890) 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');
