The ErrorHandler component provides tools to manage errors and ease debugging PHP code.

Getting Started

$ composer require symfony/error-handler
use Symfony\Component\ErrorHandler\Debug;
use Symfony\Component\ErrorHandler\ErrorHandler;
use Symfony\Component\ErrorHandler\DebugClassLoader;


// or enable only one feature

// If you want a custom generic template when debug is not enabled
// HtmlErrorRenderer::setTemplate('/path/to/custom/error.html.php');

$data = ErrorHandler::call(static function () use ($filename, $datetimeFormat) {
    // if any code executed inside this anonymous function fails, a PHP exception
    // will be thrown, even if the code uses the '@' PHP silence operator
    $data = json_decode(file_get_contents($filename), true);
    $data['read_at'] = date($datetimeFormat);
    file_put_contents($filename, json_encode($data));

    return $data;
