What are the potential drawbacks of changing the column type in a MySQL table to Varchar(200) for limiting output in PHP?

Changing the column type to Varchar(200) may lead to increased storage space usage and slower query performance. To limit the output in PHP without changing the column type, you can simply fetch the data from the database and truncate it in PHP using functions like substr(). 

// Fetch the data from the database
$query = "SELECT column_name FROM table_name";
$result = mysqli_query($connection, $query);

// Limit the output in PHP
while($row = mysqli_fetch_assoc($result)) {
    $limited_output = substr($row['column_name'], 0, 200);
    echo $limited_output;
}
