Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 212,773 loops for a total of 4,255,460 runs.
- Line execution difference (0.000011) milliseconds.
- Avg difference (2.274) milliseconds per 212,773 loops.
- Total difference 45.48 milliseconds for 4,255,460 loops
The iteration variablity for Code 1 was (7.6589) milliseconds and Code 2 was (4.6218) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "exec()", was:
exec('ls');
The second test, "shell_exec()", was:
shell_exec('ls');
