Here is an example of a custom WordPress plugin that checks the configuration of opcache and displays how much memory is allocated to it. This plugin will create a custom admin screen that displays the opcache memory.
First, we need to create the plugin file and add the required information at the top of the file:
ChatGPT
<?php
/*
Plugin Name: OPCache Memory Checker
Description: This plugin checks the configuration of opcache and displays how much memory is allocated to it.
Version: 1.0
Author: Your Name
*/
Next, we need to create a function that checks the configuration of opcache and returns the amount of memory allocated to it. We can use the ini_get function to retrieve the value of the opcache.memory_consumption configuration setting.
ChatGPT
function check_opcache_memory() {
  $memory = ini_get('opcache.memory_consumption');
  return $memory;
}
Now, we need to create the custom admin screen that will display the opcache memory. We can do this by hooking into the admin_menu action and adding a new menu item for our plugin.
ChatGPT
add_action('admin_menu', 'opcache_memory_menu');
function opcache_memory_menu() {
  add_menu_page(
    'OPCache Memory',
    'OPCache Memory',
    'manage_options',
    'opcache-memory',
    'opcache_memory_page',
    'dashicons-performance',
    75
  );
}
The add_menu_page function takes several arguments: the page title, the menu title, the capability required to access the menu, the menu slug, the function that will render the content of the page, and the icon to display next to the menu item.
Finally, we need to create the opcache_memory_page function that will render the content of our custom admin screen. This function will use the check_opcache_memory function we created earlier to retrieve the opcache memory and display it on the page.
ChatGPT
function opcache_memory_page() {
  $memory = check_opcache_memory();
  echo '<h1>OPCache Memory</h1>';
  echo '<p>Memory allocated to OPCache: '.$memory.'MB</p>';
}
This is the complete plugin code:
ChatGPT
<?php
/*
Plugin Name: OPCache Memory Checker
Description: This plugin checks the configuration of opcache and displays how much memory is allocated to it.
Version: 1.0
Author: Your Name
*/

function check_opcache_memory() {
  $memory = ini_get('opcache.memory_consumption');
  return $memory;
}

add_action('admin_menu', 'opcache_memory_menu');
function opcache_memory_menu() {
  add_menu_page(
    'OPCache Memory',
    'OPCache Memory',
    'manage_options',
    'opcache-memory',
    'opcache_memory_page',
    'dashicons-performance',
    75
  );
}

function opcache_memory_page() {
  $memory = check_opcache_memory();
  echo '<h

To continue the plugin, we can add additional features and options to the custom admin screen. For example, we can add a form that allows the user to change the value of the opcache.memory_consumption setting and save the changes.
To do this, we can add a form to the opcache_memory_page function and use the update_option function to save the changes.
ChatGPT
function opcache_memory_page() {
  $memory = check_opcache_memory();
  echo '<h1>OPCache Memory</h1>';
  echo '<p>Memory allocated to OPCache: '.$memory.'MB</p>';

  if (isset($_POST['submit'])) {
    update_option('opcache_memory_consumption', $_POST['opcache_memory_consumption']);
    $memory = check_opcache_memory();
  }

  echo '<form method="post">';
  echo '<label>Memory Consumption:</label>';
  echo '<input type="number" name="opcache_memory_consumption" value="'.$memory.'">';
  echo '<input type="submit" name="submit" value="Save">';
  echo '</form>';
}
This is a basic example of how to create a custom WordPress plugin that checks the configuration of opcache and displays how much memory is allocated to it. You can extend this plugin with additional features and options to suit your needs.
