Why is error handling important in PHP scripts, and what considerations should be made for handling errors in the context of the script discussed in the forum thread?

Error handling is important in PHP scripts to ensure that any unexpected issues or bugs are caught and dealt with appropriately. In the context of the script discussed in the forum thread, it is crucial to handle errors such as database connection failures, query errors, and file handling issues to prevent the script from crashing or displaying sensitive information to users. 

// Set error reporting level and display errors
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = mysqli_connect($servername, $username, $password, $dbname);

// Check for errors in database connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

// Perform database query
$sql = "SELECT * FROM table";
$result = mysqli_query($conn, $sql);

// Check for query errors
if (!$result) {
    die("Query failed: " . mysqli_error($conn));
}

// Handle file operations
$file = "example.txt";
$handle = fopen($file, "r");

// Check for file handling errors
if (!$handle) {
    die("Error opening file: " . error_get_last()['message']);
}

// Close database connection and file handle
mysqli_close($conn);
fclose($handle);
