+
+ Core Extensions
+
+
+ These extensions are built into the PHP core
+ and are included in every PHP installation.
+ They cannot be disabled or removed at compile time.
+
+
+ Some core extensions provide compile-time configuration options
+ that allow for customization of specific behaviors or functionality.
+
+
+ For clarity, some of the functionality listed below
+ is provided by the standard extension
+ and does not represent distinct, standalone extensions.
+ These features are described separately for convenience
+ and to highlight the specific aspects of functionality they provide.
+
+ ">
+
+ Bundled Extensions
+
+
+ These extensions and features are included with PHP,
+ but may not always be enabled by default.
+ Each can be disabled during compilation.
+
+
+ Some bundled extensions require specific system resources
+ or may offer additional functionality
+ when supplementary libraries are installed.
+ In some cases, their availability is limited
+ to certain platforms or use cases.
+
+ ">
+
+ External Extensions
+
+
+ These extensions are included with PHP,
+ but require require external libraries to be enabled.
+ Each can be enabled during compilation
+ (if dependency requirements are met).
+
+ ">
+
+ PECL Extensions
+
+
+ These extensions are available from &link.pecl;.
+ They may require external libraries
+ or have other special requirements.
+ More PECL extensions exist
+ but they are not documented in the PHP manual yet.
