How to get all methods in an object in php

In PHP, it is very simple to obtain all the methods in an object, which can be achieved by using the ReflectionClass class in the PHP standard library. The ReflectionClass class provides a method to reflect all information of a class in PHP, including class name, attributes, methods, etc. Below we introduce in detail how to use the ReflectionClass class to obtain all methods in an object.

1. Create a ReflectionClass object

First, we need to create a ReflectionClass object, which can be achieved by class name or object. If you already have a class name, you can create a ReflectionClass object directly as follows:

$reflectionClass = new ReflectionClass('ClassName');

If it is an object, you can create it as follows:

$reflectionClass = new ReflectionClass($object);

Here $object is a Object that has been instantiated.

2. Get the names of all methods of the object

Once we have the ReflectionClass object, we can use the getMethods() method to get all the methods in the class method. The getMethods() method returns an array of ReflectionMethod objects, and the getName() method in the ReflectionMethod object can obtain the method name. Here is an example:

$reflectionClass = new ReflectionClass('ClassName');
$methods = $reflectionClass->getMethods();
foreach ($methods as $method) {
    echo $method->getName() . "\n";
}

The above code will output all the method names in the ClassName class, with each method name on a separate line.

3. Get detailed information about all methods of the object

In addition to getting the method name, the ReflectionClass class also provides the following methods to help you get More information about object methods:

• Class.getName(): Get the class name;
• Class.getMethods(): Get all methods of the specified class or object;
• Method.getName(): Get the method name;
• Method.isAbstract(): Determine whether the method is an abstract method;
• Method.isConstructor(): Determine whether the method is a constructor Method;
• Method.isFinal(): Determine whether the method is final method;
• Method.isPrivate(): Determine whether the method is private method;
• Method.isProtected( ): Determine whether the method is a protected method;
• Method.isPublic(): Determine whether the method is a public method;
• Method.isStatic(): Determine whether the method is a static method;

In addition to the methods mentioned above, the ReflectionClass class has many other methods and properties that can be used. They can help you get all the information of the class at runtime, including constants, properties, etc.

Summary

Through the ReflectionClass class, you can simply get all the methods in an object. These methods include the method name, whether it is an abstract method, and whether it is a constructor method. etc. In actual development, the ReflectionClass class has many other useful methods and properties that can be used according to specific needs.
