Appendix B. PHPAPI

B PHPAPI

THE PHP CORE AND EXTENSION LAYERS EXPORT A WIDE RANGE of functions meant to provide access to the SAPI, TSRM, and Engine layers as well as address common needs for the web-based environment common to most implementations of PHP. These API calls cover topics such as simple string manipulation, access to file and console I/O, and request resource management. In this appendix you'll see the extensive catalog of core API methods, its equally massive streams layer sibling, and the standard portion of the extension APIs.
