How can error reporting be effectively utilized in PHP to identify issues with database queries and object instantiation?

To effectively utilize error reporting in PHP to identify issues with database queries and object instantiation, you can enable error reporting, set error reporting level to include warnings and notices, and handle errors using try-catch blocks for database queries and object instantiation.

// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Set error reporting level to include warnings and notices
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);

try {
    // Database connection
    $conn = new mysqli($servername, $username, $password, $dbname);

    // Handle database query errors
    if ($conn->connect_error) {
        throw new Exception("Connection failed: " . $conn->connect_error);
    }

    // Object instantiation
    $obj = new MyClass();

    // Handle object instantiation errors
    if (!$obj) {
        throw new Exception("Failed to instantiate object");
    }
} catch (Exception $e) {
    echo "Error: " . $e->getMessage();
}
