Description Author

This class can analyze PHP code to check if it uses non-builtin extensions.

It can take the path of a given PHP source file or directory and parses the source files to find out calls to known functions, classes or constants defined by those PHP extensions.

The class can output a report that tells what PHP extensions are used in the code, denoting if each extension is bundled with PHP or not, the first and last versions of PHP the extension was made available, if the extension development is dead, if it is available in PECL repository or if it is a Windows specific extension.

The information about the detected extensions is read for a separate data directory that can be updated with information about other extensions not yet detected.

Over the years many developers have worked on code that now may be considered legacy.

Some code relies on PHP extensions that existed in past PHP versions but may not be available in future versions.

This package is a tool that can examine your PHP code and tell which extensions it relies, as wel in which PHP versions those extensions are supported.
