What are the potential issues with using Latin1 as the collation for the SQL column?

Using Latin1 as the collation for an SQL column can lead to problems with storing and displaying non-Latin characters properly, as it only supports a limited character set. To solve this issue, you can change the collation of the column to a more suitable one like UTF8_general_ci, which supports a wider range of characters.

// Change the collation of the SQL column to UTF8_general_ci
$sql = "ALTER TABLE your_table MODIFY your_column VARCHAR(255) CHARACTER SET utf8 COLLATE utf8_general_ci;";
$result = mysqli_query($conn, $sql);

if($result) {
    echo "Collation changed successfully.";
} else {
    echo "Error changing collation: " . mysqli_error($conn);
}
