PHP get_class_methods() Function: Usage and Examples

The PHP get_class_methods API performs a focused operation on an object or value. The examples below show its effect on actual data.

Lists methods accessible from the current scope.

What Is get_class_methods in PHP?

Lists methods accessible from the current scope.

Syntax:

get_class_methods(object|string $object_or_class): array

The method accepts the following parameters:

• $object_or_class — Required. A object|string parameter named object_or_class; the examples below show a supported value.

Return type declared by PHP: array. The value or side effect is demonstrated in the examples below.

Example 1: Basic Usage

This example uses a small input to make the main behavior visible.

<?php

class TaskRunner { public function start(): void {} private function reset(): void {} }
print_r(get_class_methods(TaskRunner::class));

Output:

Array
(
    [0] => start
)

Lists methods accessible from the current scope.

Example 2: A Different Input

A different set of values shows the same operation in another situation.

<?php

class TaskRunner { public function start(): void {} private function reset(): void {} }
print_r(get_class_methods(TaskRunner::class));
// The output reflects definitions in this PHP process.

Output:

Array
(
    [0] => start
)

Visibility affects which methods appear in the result.

Practical Example: Applying the Feature

This example shows an application-style use of the feature, with its surrounding setup visible.

<?php

class TaskRunner { public function start(): void {} private function reset(): void {} }
print_r(get_class_methods(TaskRunner::class));
// Use this result while deciding how to handle optional application features.

Output:

Array
(
    [0] => start
)
