This part lists extensions not intended for the production use - they are either too "old" (deprecated) or "new" (experimental).
These extensions have been deprecated usually in the favor of some other extensions.
The behaviour of these extensions - including the names of their functions and anything else documented about these extensions - may change without notice in a future release of PHP. Use these extensions at your own risk.
