How to convert php function object into array

As PHP development becomes more and more complex, we need to convert objects into arrays and arrays into objects to process data more conveniently. Especially when processing the returned data, we often need to convert the object returned in the function into an array. This process is very common in programming.

In PHP language, we can use two methods to convert function objects into arrays. One is to use the properties of the object and combine them into an array, and the other is to use the get method of the object to combine the returned results into an array.

Let’s take a closer look at the use and implementation process of these two methods.

1. Using the properties of the object

The properties of the object can be accessed directly, so we can use the properties of the object to combine them into an array, as shown below:

function getObjectData($object) {
    $data = array();
    foreach (get_object_vars($object) as $key => $value) {
        $data[$key] = $value;
    }
    return $data;
}

In this function, we first use PHP's get_object_vars() function to obtain the attribute list of the object, and then use a loop to traverse the list, combine the attribute name and attribute value into an array and return it. This way we can convert a function object into an array.

2. Use the get method of the object

If the properties of the object are private or protected, we cannot access them directly, but in general the object will provide Some get methods through which you can access the properties of the object. Therefore, we can use the object's get method to combine their values ​​into an array, as shown below:

function getObjectData($object) {
    $data = array();
    $class_methods = get_class_methods($object);
    foreach ($class_methods as $method_name) {
        if (substr($method_name, 0, 3) == 'get') {
            $key = strtolower(substr($method_name, 3));
            $data[$key] = $object->$method_name();
        }
    }
    return $data;
}

In this function, we first get the list of all methods of the object using PHP's get_class_methods() function, Then use a loop to traverse the list, find the method starting with get, intercept the attribute name and convert it to lowercase, and finally use the object's get method to obtain the attribute value and combine it into an array. This way we can convert a function object into an array.

Summary

The above are two methods of converting function objects into arrays. Which method to use depends on your needs and the special circumstances of the object. If the properties of the object are public, it is simpler and more straightforward to use the first method, otherwise you need to use the second method. It should be noted that in the case of inheritance and polymorphism, these methods may not work or may cause errors, so special handling is required. In actual programming, you need to use it flexibly and choose the appropriate method based on the specific situation.
