  • The Debug Component
The Debug component provides tools to ease debugging PHP code.

Installation¶

Note

If you install this component outside of a Symfony application, you mustrequire the vendor/autoload.php file in your code to enable the classautoloading mechanism provided by Composer. Readthis article for more details.

Usage¶

Intel rapid storage technology driver windows 10 64 bit dell. The Debug component provides several tools to help you debug PHP code.Enable all of them by calling this method:

The enable() method registers anerror handler, an exception handler anda special class loader.

Read the following sections for more information about the different availabletools.

Caution

Xdebug Php Docker

You should never enable the debug tools, except for the error handler, in aproduction environment as they might disclose sensitive information to the user.

Enabling the Error Handler¶

The SymfonyComponentDebugErrorHandler class catches PHP errorsand converts them to exceptions (of class ErrorException orSymfonyComponentDebugExceptionFatalErrorException for PHPfatal errors):

This error handler is enabled by default in the production environment when theapplication uses the FrameworkBundle because it generates better error logs.

Enabling the Exception Handler¶

Symfony

The SymfonyComponentDebugExceptionHandler class catchesuncaught PHP exceptions and converts them to a nice PHP response. It is usefulin debug mode to replace the default PHP/XDebug output with something prettierand more useful:

Note

If the HttpFoundation component isavailable, the handler uses a Symfony Response object; if not, it fallsback to a regular PHP response.

Debugging a Class Loader¶

The SymfonyComponentDebugDebugClassLoader attempts tothrow more helpful exceptions when a class isn’t found by the registeredautoloaders. All autoloaders that implement a findFile() method are replacedwith a DebugClassLoader wrapper.

Using the DebugClassLoader is done by calling its staticenable() method:
