扩展,添加了对 PHP 中原始类型方法调用的支持
This extension implements the ability to register a class that handles the
method calls to a certain primitive type (string, array, ...). As such it
allows implementing APIs like $str->length().
The main purpose of this repo is to provide a proof of concept implementation that can be used to design the new APIs. The switch to object syntax for operations on primitive types is a unique opportunity for PHP to redesign many of its inconsistent core APIs. This repo provides the means to quickly prototype and test new APIs as userland code. Once the APIs are figured out it will be proposed for inclusion into PHP.
Note: The ability to register type handlers from userland is just for prototyping. It's not something I would actually want in PHP in the end.
Type handlers are registered through register_primitive_type_handler. The
function takes a type name (like "string" or "array") and a class name. The
class should contain static methods, which receive the primitive type as the
first parameter:
length()); // int(3)
var_dump($string->startsWith("a")); // bool(true)
The valid type names are: null, bool, int, float, string, array
and resource. Not all of those will make sense in practice, but for now they
are all supported.
As already pointed out in the introduction the main purpose of this repo is
designing good APIs for the primitive types. The implemented APIs are available
in the handlers/ folder (and are obviously work in progress). In order to
load these APIs just include the handlers/bootstrap.php file.
The master branch supports PHP version 7.0 to 8.1. The extension is incompatible with the JIT compiler.
In order to compile and install the extension run the following commands:
phpize
./configure
make
sudo make install
Download a prebuilt Windows DLL that matches your PHP version
and move it into the ext/ directory of your PHP installation. Furthermore
you'll have to add extension=php_scalar_objects.dll to your php.ini.
The extension comes with a run-tests.php file to run the tests. (To see
examples of the implemented APIs you should also look in the tests.) The
script is run as follows:
php run-tests.php -q -p php
Where php is the path to your PHP executable.
This extension has a number of limitations:
$self within the methods is not possible (or rather, will have no effect,
as you'd just be changing a copy).暂无开放 Issues，或尚未同步最近议题。
