How can the lack of error messages in PHP MySQL queries impact the integrity of data being inserted into a table with unsigned integer constraints?

The lack of error messages in PHP MySQL queries can lead to data being inserted into a table with unsigned integer constraints without proper validation. This can result in data being truncated or converted to 0, affecting the integrity of the data. To solve this issue, it is important to check for errors after executing MySQL queries and handle them appropriately. 

<?php
// Connect to MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

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

// Execute MySQL query
$query = "INSERT INTO table_name (column_name) VALUES ($value)";
if ($mysqli->query($query) === TRUE) {
    echo "Data inserted successfully";
} else {
    echo "Error: " . $mysqli->error;
}

// Close MySQL connection
$mysqli->close();
?>
