What are the potential pitfalls of using an INT data type in MySQL to store values from radio buttons in PHP forms?

Using an INT data type in MySQL to store values from radio buttons in PHP forms can lead to potential pitfalls such as data inconsistency and difficulty in querying the database. To solve this issue, you can use ENUM data type in MySQL to restrict the values that can be stored in the column to only those specified in the radio buttons. 

// Define the ENUM data type in MySQL for the column
$enumValues = "'value1', 'value2', 'value3'";
$sql = "ALTER TABLE your_table MODIFY column_name ENUM($enumValues)";

// Execute the SQL query to change the data type to ENUM
if ($conn->query($sql) === TRUE) {
    echo "Column data type changed to ENUM successfully";
} else {
    echo "Error changing column data type: " . $conn->error;
}
