What is the difference between `try-except` and `try-finally`

The `try-except` and `try-finally` blocks are both used in exception handling in programming, but they serve different purposes.

try-except

The `try-except` block is used to catch and handle exceptions. If an exception occurs in the `try` block, the control is passed to the `except` block, where the programmer can handle the error gracefully.

try-finally

The `try-finally` block is used to ensure that certain cleanup actions are performed regardless of whether an exception occurs. The code inside the `finally` block will execute after the `try` block finishes executing, even if an exception was raised.

Example

<?php try { // Code that may throw an exception throw new Exception("An error occurred"); } catch (Exception $e) { // Handle the exception echo "Caught exception: " . $e->getMessage(); } try { // Code that may throw an exception echo "Executing try block"; } finally { // This block will always execute echo "Executing finally block"; } ?>
