README
This library is deprecated. Please use BetterReflection.
Parser Reflection API library provides a set of classes that extend original internal Reflection classes, but powered by PHP-Parser library thus allowing to create a reflection instance without loading classes into the memory.
This library can be used for analysing the source code; for automatic proxy creation and much more.
Installation
Library can be installed with Composer. Installation is quite easy:
$ composer require goaop/parser-reflection
Composer will install the library to your project's vendor/goaop/parser-reflection
directory.
Usage
Initialization
Prior to the first use library can be optionally initialized. If you use Composer for installing packages and loading classes, then you shouldn't worry about initialization, library will be initialized automatically.
If project uses a custom autoloader then you should follow the next steps:
- Create a new class that implements
\Go\ParserReflection\LocatorInterface
- Create an instance of that class and pass it to the
ReflectionEngine::init()
method for initial configuration
Reflecting concrete classes/methods/properties without loading them
Just use Go\ParserReflection
package reflection classes like traditional ones:
$parsedClass = new \Go\ParserReflection\ReflectionClass(SomeClass::class); var_dump($parsedClass->getMethods()); $parsedMethod = new \Go\ParserReflection\ReflectionMethod(SomeClass::class, 'someMethod'); echo (string)$parsedMethod;
Or you can use an additional classes ReflectionFile
and ReflectionFileNamespace
to analyse a raw PHP files:
$parsedFile = new \Go\ParserReflection\ReflectionFile('SomeClass.php'); $fileNameSpaces = $parsedFile->getFileNamespaces(); // We can iterate over namespaces in the file foreach ($fileNameSpaces as $namespace) { $classes = $namespace->getClasses(); // Iterate over the classes in the namespace foreach ($classes as $class) { echo "Found class: ", $class->getName(), PHP_EOL; // Now let's show all methods in the class foreach ($class->getMethods() as $method) { echo "Found class method: ", $class->getName(), '::', $method->getName(), PHP_EOL; } // ...all properties in the class foreach ($class->getProperties() as $property) { echo "Found class property: ", $class->getName(), '->', $property->getName(), PHP_EOL; } } }
How it works?
To understand how library works let's look at what happens during the call to the new \Go\ParserReflection\ReflectionClass(SomeClass::class)
\Go\ParserReflection\ReflectionClass
asks reflection engine to give an AST node for the given class name- Reflection engine asks a locator to locate a filename for the given class
ComposerLocator
instance asks the Composer to find a filename for the given class and returns this result back to the reflection engine- Reflection engine loads the content of file and passes it to the PHP-Parser for tokenization and processing
- PHP-Parser returns an AST (Abstract Syntax Tree)
- Reflection engine then analyse this AST to extract specific nodes and wrap them into corresponding reflection classes.
Compatibility
All parser reflection classes extend PHP internal reflection classes, this means that you can use \Go\ParserReflection\ReflectionClass
instance in any place that asks for \ReflectionClass
instance. All reflection methods should be compatible with original ones, providing an except methods that requires object manipulation, such as invoke()
, invokeArgs()
, setAccessible()
, etc. These methods will trigger the process of class loading and switching to the internal reflection.
