How can one troubleshoot and resolve issues related to MySQL tables not functioning properly in PHP scripts?

If MySQL tables are not functioning properly in PHP scripts, the issue may be related to incorrect table names, column names, or SQL queries. To troubleshoot and resolve this, double-check the table and column names in the database, ensure the SQL queries are correct, and verify the connection to the database is established successfully. 

// Example PHP code snippet to troubleshoot and resolve MySQL table issues
// Ensure the correct table and column names are used in the SQL query
$query = "SELECT * FROM users";

// Establish a connection to the MySQL database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Check if the connection is successful
if (!$connection) {
    die("Connection failed: " . mysqli_connect_error());
}

// Perform the SQL query
$result = mysqli_query($connection, $query);

// Check if the query was successful
if ($result) {
    // Process the query results
    while ($row = mysqli_fetch_assoc($result)) {
        echo "ID: " . $row['id'] . " - Name: " . $row['name'] . "<br>";
    }
} else {
    echo "Error: " . mysqli_error($connection);
}

// Close the connection
mysqli_close($connection);
