How can error handling be improved in PHP scripts to troubleshoot issues with data not being written to a database?

When data is not being written to a database in PHP scripts, error handling can be improved by implementing proper error reporting and exception handling. This can help identify any issues with database connections, query execution, or data validation that may be causing the problem. By using try-catch blocks and error reporting functions like error_reporting() and mysqli_error(), developers can troubleshoot and resolve issues more effectively. 

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

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

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Insert data into database
$sql = "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')";

if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
?>
