+Subject: [PATCH] php: add arginfo to php bindings
+
+Starting with PHP8, arginfo is mandatory for PHP extensions. This patch
+updates the generator for the PHP bindings to generate the arginfo
+structures, using the Zend API macros. Only basic arginfo is added,
+without full documentation of argument and return types, in order to
+ensure compatibility with as many versions of PHP as possible.
