Historical ResultsBased on (3) saved test runs, The test labeled "exec()" was (on average) the faster by 0.0293 seconds, (3.328% faster)
The exec() test took 0.8499 seconds.
The shell_exec() test took 0.8792 seconds.
Each test case ran 20 random code order iterations consisting of 180,476 loops for a total of 3,609,520 runs.
- Line execution difference (0.000008) milliseconds.
- Avg difference (0.000) milliseconds per 180,476 loops.
- Total difference 29.26 milliseconds for 3,609,520 loops
The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "exec()", was:
The second test, "shell_exec()", was:
