Result: Discarded
The test labeled "shell_exec()" was the faster by 0.0473 seconds, (4.652% faster)
The shell_exec() test took 0.9694 seconds.
The system() test took 1.0167 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 229,479 loops for a total of 4,589,580 runs.
- Line execution difference (0.000010) milliseconds.
- Avg difference (2.365) milliseconds per 229,479 loops.
- Total difference 47.30 milliseconds for 4,589,580 loops
The iteration variablity for Code 1 was (9.2604) milliseconds and Code 2 was (7.5523) 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');
