How can error handling be improved in the PHP script to provide more informative messages to developers and users?

The issue with error handling in the PHP script can be improved by implementing custom error handling functions that provide more informative messages to developers and users. This can be achieved by using the set_error_handler() function to define a custom error handler function that logs detailed error messages or sends notifications to developers. Additionally, using try-catch blocks for exception handling can help catch and handle specific types of errors gracefully. 

// Define custom error handler function
function customErrorHandler($errno, $errstr, $errfile, $errline) {
    // Log or send detailed error messages to developers
    error_log("Error: [$errno] $errstr in $errfile on line $errline");
    // Display user-friendly error message
    echo "An error occurred. Please try again later.";
}

// Set custom error handler
set_error_handler("customErrorHandler");

// Example code with potential error
$var = 1;
if ($var === '1') {
    // Triggering a type mismatch error
    trigger_error("Type mismatch error", E_USER_ERROR);
}
