StudyLIC v.1.0

This is a small free PHP profiler, the functionality of which is specifically designed for the needs of web studios:

• to show potential areas where the client's website is slowing down;
• to measure how the load changes after installing a plugin, component, or developed theme;
• to evaluate which of the selected CMS is less cumbersome in accordance with the technical requirements of the new project.

The measured parameters are the number of PHP preprocessor ticks used, the amount of memory consumed in excess of the allocated amount, the time spent processing the browser request to the CMS under study, and the number of script files involved.

Design features

• The installer, uninstaller and measurement block are combined into one file studyLIC-installer.php.
• Built-in ability to save the measurement report as a static HTML file.
• Multilingual interface: English (default), Russian.

For testing purposes, a folder named app-example was also added to the repository, containing an application of 3 files.

System requirements

• A web server, Apache 2.x, for example.
• PHP version 7.x or above.

How to install

1. Copy the studyLIC-installer.php file to the directory of the application being analyzed. Let's assume that directory has the URL //localhost/app-example/.

2. Open the URL //localhost/app-example/studyLIC-installer.php in your browser. That is the installer. It will automatically set observation points in all script files in your application and display a report as a file list. This moment is shown in the following demo screenshot.
