How do you handle errors in PHP using try-catch blocks

Handling errors in PHP using try-catch blocks is a powerful method for managing exceptions and ensuring that your application can handle unexpected situations gracefully. The try-catch construct allows you to "try" a block of code, and if an exception occurs, it will "catch" that exception and let you handle it accordingly.

Here’s a basic example of how to use try-catch blocks in PHP:


    <?php
    class CustomException extends Exception {}

    function testException($number) {
        if ($number > 1) {
            throw new CustomException("Number must be 1 or 0");
        }
        return "Number is valid.";
    }

    try {
        echo testException(2);
    } catch (CustomException $e) {
        echo 'Caught exception: ',  $e->getMessage(), "\n";
    } catch (Exception $e) {
        echo 'Caught generic exception: ',  $e->getMessage(), "\n";
    }
    ?>
