In javascript, you can console.log(‘whatever”) in your browser for troubleshooting. However, in php code, a little bit trick is required to do so. Here are the steps:

    function debug_to_console($data) {
        $output = $data;
        if (is_array($output))
            $output = implode(',', $output);

        echo "<script>console.log('Debug Objects: " . $output . "' );</script>";
    }
  1. In the line that you need to console log, add this code

    debug_to_console(“Test”);

  2. If what you need to debug is an object, you can also log it via

    debug_to_console(json_encode($foo));

Open developer browser, and you should be able to see the console.log of the php object.
