Why is the catch handler not being triggered in the provided PHP code snippet?

The catch handler is not being triggered in the provided PHP code snippet because the try block does not contain any code that throws an exception. To trigger the catch handler, an exception needs to be thrown within the try block. This can be done using the "throw new Exception()" statement. 

try {
    // Code that may throw an exception
    throw new Exception("An error occurred.");
} catch (Exception $e) {
    echo "Caught exception: " . $e->getMessage();
}
