Lightweight PHP profiler class

Developer website

This class uses for profiling PHP applications. It's very useful tool for finding slow places in your apps.

The class provides follow functions:

• Set time point
• Print function trace
• Print overall report as an HTML comment on website page
• Works with error_log for easily control AJAX and other queries
• Divides traces and time points by group
• Prints overall work times report in a table. It can be divided into groups.
• Detects memory usage

With this solution, you don't need huge solutions. You can setup this profiler only for development mode. It's only 2 files:

• Profiler class
• ASCII table class

Once you've included file, you can use it. You can find slow places in your application, you can find break places in your code etc. I recommend to include profiler as top as possible. If you wish to use final report I recommend place code as end as possible.

Error log output is enabled by default.

Installation

require_once('phpprofiler/profiler.class.php');
