Historical ResultsBased on (2) saved test runs, The test labeled "exec()" was (on average) the faster by 0.0151 seconds, (1.476% faster)
The exec() test took 1.0083 seconds.
The shell_exec() test took 1.0234 seconds.
Each test case ran 20 random code order iterations consisting of 273,214 loops for a total of 5,464,280 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.000) milliseconds per 273,214 loops.
- Total difference 15.11 milliseconds for 5,464,280 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:
