Historical Results

Based on (3) saved test runs, The test labeled "system()" was (on average) the faster by 0.0072 seconds, (0.798% faster)

system() 100%
shell_exec() 99.202%

The system() test took 0.891 seconds.
The shell_exec() test took 0.8982 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 248,433 loops for a total of 4,968,667 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.000) milliseconds per 248,433 loops.
  • Total difference 7.17 milliseconds for 4,968,667 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.

Code

The first test, "system()", was:

system('ls');

The second test, "shell_exec()", was:

echo shell_exec('ls');
