+ When building a PHP or
+ Zend extension with
+ :ext or :zend, these
+ variables can be set:
+
+
+
+ PHP_MODNAME
+
+ The name of the PHP or
+ Zend extension. Default value
+ is ${PORTNAME}.
+
+
+
+
+ PHP_HEADER_DIRS
+
+ A list of subdirectories from which to install header
+ files. The framework will always install the header files
+ that are present in the same directory as the
+ extension.
+
+
+
+
+ PHP_MOD_PRIO
+
+ The priority at which to load the extension. It is a
+ number between 00 and
+ 99.
+
+ For extensions that do not depend on any extension,
+ the priority is automatically set to
+ 20, for extensions that depend on
+ another extension, the priority is automatically set to
+ 30. Some extensions may need to be
+ loaded before every other extension, for example www/php56-opcache. Some may need
+ to be loaded after an extension with a priority of
+ 30. In that case, add
+ PHP_MOD_PRIO=XX
+ in the port's Makefile. For example:
+
+ USES= php:ext
+USE_PHP= wddx
+PHP_MOD_PRIO= 40
