Testing the functions

The number of functions is growing fast and so it becomes hard to maintain quality.

To defeat that danger of bad code, syntax errors, etc, I've added a new feature: php.js tester.

It is an automatically generated page that includes ALL functions in your browser, and then extracts specific testing information from each function's comments. This info is then used to run the function, and the return value is compared to a predefined one.

This way code is always checked on syntax errors, and if it doesn't function correctly anymore after an update, we should also be able to detect it more easily.

If you want, go check it out.

Coming Project features

Project features that we are currently working on:

• Versioning. Individual functions are versioned, but the entire library should be versioned as well.
• Light. A lightweight version of php.js should be made available with only common functions in it.
