How is error handling and exception management implemented in your application?

In PHP, error handling and exceptional situations are usually implemented using try-catch blocks and exception classes (Exception).

When an error occurs in the code, an exception can be thrown using throw. The code that might throw an exception is placed inside the try block, and the handling of this exception is done in the catch block.

Example:

try {
    $file = fopen('somefile.txt', 'r');
    if (!$file) {
        throw new Exception('Failed to open file');
    }
    // work with the file
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}

You can also create your own exception classes for more precise handling of different error types.

In applications, centralized error handling is usually implemented, for example, through exception handlers, logging, and notifications, to ensure stability and informativeness when problems occur.
