Wordpress php print to console

Debugging PHP can be a pain in WordPress. Add this handy code snippet to your theme’s functions.php file. The function will log PHP data to your browser’s console.

/**
 * @param ...$data
 *
 * @return void
 */
function my_console_log(...$data) {
    $json = json_encode($data);
    add_action('shutdown', function() use ($json) {
       echo "";
    });
}

// Example usage
my_console_log(['foo' => 'bar'], null, 1, 'hi');

WP Console brings the famous PsySH on your browser. PsySH is a runtime developer console, interactive debugger and REPL for PHP.

Write your code in code editor, press Cmd-Enter(mac) or Ctrl-Enter(win/linux) and get your output in your browser.

You can also use PsySH with wp-cli with the command wp shell. wp-cli has built-in support for psysh already. You need to just activate WP Console to use this.

Features

• Powerful code editor powered by Ace Editor.
• PHP core and WordPress functions live autocompletion with placeholders.
• _dump as the alternative to var_dump which uses Symfony VarDumper.
• Get debug.log contents and clear them right from your browser.
• Advanced shell powered by psySH for wp shell.
• Custom code snippet. Supports VS Code supported code snippets. For example you can use this WooCommerce snippets.

Please note that, currently PsySH commands like ls, doc, show etc and Magic variables like $_, $__class etc are not supported in browser console.

👉 WP Console uses Gutenberg packages and components for its UI/UX. Checkout the GitHub repo here ediamin/wp-console.

Security Concern

WP Console explicitly checks for manage_options permission to display the UI and perform other actions. Yet, this plugin should not be used in production server.
