Package: PHP Backwards Compatibility Library
If your PHP applications rely on parts of the language that were changed, you may need to change your code to keep it working in the new PHP version that runs on the machine your PHP application is running.
Suppose your PHP application relies on PHP function or other parts of the language that changed in a backward incompatibility way. In that case, you may need to change your PHP application code to adapt to the PHP version changes.
This package provides a library of scripts with PHP functions that emulate the functions introduced in newer PHP versions.
Using this library, you can adapt your PHP application code to make it work in a newer PHP version without having to upgrade the PHP version that you use in the environment your PHP application is running.
This way, you can change your PHP application code to prepare to make it work in newer PHP versions making a smooth transition between PHP versions.
