Source Code Context

<?php
  82   * the `$accepted_args` value must reflect the number of arguments the bound callback *actually*
  83   * opted to accept. If no arguments were accepted by the callback that is considered to be the
  84   * same as accepting 1 argument. For example:
  85   *
  86   *     // Filter call.
  87   *     $value = apply_filters( 'hook', $value, $arg2, $arg3 );
  88   *
  89   *     // Accepting zero/one arguments.
  90   *     function example_callback() {
  91   *         ...
  92   *         return 'some value';

 * The plugin API is located in this file, which allows for creating actions

 * then be run when the action or filter is called.
 *
 * The API callback examples reference functions, but can be methods of classes.
 * To hook methods, you'll need to pass an array one of two ways.
