This tool helps writing benchmarks that can be run during testing or some other automated deployment procedure.
Command line options:
$ phpbench bench -h
Usage:
bench [options] [--] [<fileOrDir>]
Arguments:
fileOrDir file or directory with benchmarks
Options:
-f, --format[=FORMAT] output format: txt, csv. [default: "txt"]
-i, --iterations[=ITERATIONS] number of benchmarking iterations [default: 10000]
-h, --help Display this help message
-q, --quiet Do not output any message
-V, --version Display this application version
--ansi Force ANSI output
--no-ansi Disable ANSI output
-n, --no-interaction Do not ask any interactive question
-v|vv|vvv, --verbose Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug
Help:
Run benchmark
Run all benchmarks in examples directory:
$ phpbench bench examples/
Benchmark files must end with Bench.php.
Run benchmarks from specific file:
$ phpbench bench examples/ArrayKeyExistsBench.php
Human readable:
$ ./phpbench bench examples/
