In what scenarios would it be beneficial to use try...catch blocks in PHP code, and how can they improve code robustness and maintainability?

Using try...catch blocks in PHP code can be beneficial when there are potential errors or exceptions that could occur during the execution of a script. By wrapping certain code within a try block and catching any exceptions in a catch block, you can handle errors gracefully, prevent script termination, and provide more informative error messages to users or developers. This can improve code robustness by handling unexpected situations and maintainability by centralizing error handling logic. 

try {
    // Code that may throw an exception
    $result = 10 / 0;
} catch (Exception $e) {
    // Handle the exception
    echo 'An error occurred: ' . $e->getMessage();
}
