Hi, One interesting feature of PHP 8 is the automatic generation of arginfo from a stub file.
Just thinking if this can be used for PECL extension and used in PHP 7 compatible version. A WIP exists in xattr [1] extension How it works: - arginfo are only generated when the extension is build against PHP 8, so most of the work must be done there - Build against PHP 7 will use the same file - stub.php may have some conditional for PHP 8 new features (e.g. union type usage) - some compat macro defined before including arginfo.h may be needed (e.g. ZEND_ARG_TYPE_INFO_WITH_DEFAULT_VALUE) At a first glance, it seems working and nice to use Comment welcome about this.
