README
A PHP reflection library to directly access protected/private properties and call protected/private methods. Static properties and methods can also be accessed/invoked from a class directly.
This library works with major versions of PHP from 5.3 to 8.2.
Installation
For PHP 8.0+, please use version 2.0:
composer require crowdstar/reflection:~2.0.0
For old versions of PHP (PHP 5.3 to PHP 7.4), please use version 1.0 instead:
composer require crowdstar/reflection:~1.0.0
How To Use It
Three static methods are provided to access protected/private properties and call protected/private methods of an object/class:
CrowdStar\Reflection\Reflection::getProperty()
: Get current value of a property.CrowdStar\Reflection\Reflection::setProperty()
: Set a new value to a property.CrowdStar\Reflection\Reflection::callMethod()
: Call a method of a class/object.
Here is a sample code showing how to use them:
<?php declare(strict_types=1); require __DIR__ . '/vendor/autoload.php'; use CrowdStar\Reflection\Reflection; class Helper { private string $key; private static string $keyStatic; private function get(): string { return 'Private method invoked.'; } private static function getStatic(int $i, int $j): string { return "Private static method invoked with parameter {$i} and {$j}."; } } $helper = new Helper(); // Access properties and invoke methods from objects. Reflection::setProperty($helper, 'key', 'Set value to a private property.'); echo "Output 1: ", Reflection::getProperty($helper, 'key'), PHP_EOL; echo "Output 2: ", Reflection::callMethod($helper, 'get'), PHP_EOL, PHP_EOL; // Access static properties and invoke static methods from objects. Reflection::setProperty($helper, 'keyStatic', 'Set value to a private static property.'); echo "Output 3: ", Reflection::getProperty($helper, 'keyStatic'), PHP_EOL; echo "Output 4: ", Reflection::callMethod($helper, 'getStatic', [1, 2]), PHP_EOL, PHP_EOL; // Static properties and methods can also be accessed/invoked from a class directly. Reflection::setProperty(Helper::class, 'keyStatic', 'Set another value to a private static property.'); echo "Output 5: ", Reflection::getProperty(Helper::class, 'keyStatic'), PHP_EOL; echo "Output 6: ", Reflection::callMethod(Helper::class, 'getStatic', [3, 4]), PHP_EOL; ?>
