Miscellaneous API Function

Summary

Although the preceding list of API calls might seem extensive, it pales in comparison to the number of wrapper macros, overridable callbacks, and other gems that can be found in the Zend Engine. Many of these wrapper macros have been covered in earlier chapters, such as the variable manipulating ZVAL_*() family, and the TSRM accessing *G() family. Spend some time looking through the source and other extensions and you're sure to find a few more hidden treasures.

In Appendix B, "PHPAPI," you'll round out the core API reference with a listing of functions found in the PHP core and throughout its extensions (standard, optional, and PECL).
