Dirty and simple PHP benchmark script. Tested on Linux only.
Add execute permission to benchmark_php file and move it to your PATH location for convenience.
Usage: benchmark_php [loops] [full repeats] script1.php script2.php script3.php ….
Prepare PHP scripts, that do the same thing in different ways and specify these files as arguments. Benchmark will run these scripts many times and output results immediately in table form. Optionally, you can specify "loops" and "full repeats" values as first and second argument.
In each full repeat special test script is ran in separate PHP interpreter. In test script is placed a loop with specified number of iterations. This loop contain your PHP code without <?php and ?> tags.
It's possible to specify PHP interpreter path by PHP_PATH environment variable.
Keep in mind, that your tested code will be ran from for loop. Don't use namespaces and don't define constants in tested scripts. Also, use include_once/require_once instead of include/require.
Always use absolute paths rather than relative paths. Temporary test script is saved under /tmp, so don't use magic constants like __FILE__ or __DIR__.
Output is redirected to /dev/null, so don't print text from tested code. If your code has syntax errors or trigger PHP errors, benchmark will fail.
Create three PHP scripts, that parse example settings in various formats.
