What steps can be taken to troubleshoot and resolve issues with MySQL queries not updating data as expected in PHP?

If MySQL queries are not updating data as expected in PHP, one possible issue could be incorrect query syntax or conditions. To troubleshoot and resolve this issue, carefully review the SQL query being executed and ensure that it is correctly written and the conditions are accurately specified. 

// Example code snippet to troubleshoot and resolve MySQL query not updating data as expected in PHP

// Make sure to establish a connection to the database
$connection = mysqli_connect("localhost", "username", "password", "database");

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

// Example SQL query to update data in a table
$sql = "UPDATE table_name SET column_name = 'new_value' WHERE condition";

// Execute the query
if (mysqli_query($connection, $sql)) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . mysqli_error($connection);
}

// Close the connection
mysqli_close($connection);
