What is the issue with generating an alias column in PHP when the column types are incompatible?

When generating an alias column in PHP, if the column types are incompatible, it can lead to unexpected results or errors when trying to access or manipulate the data. To solve this issue, you should ensure that the alias column has a compatible type with the original column, either by explicitly casting the data or using functions to convert it to the desired type. 

// Example code snippet to generate an alias column with compatible type
$query = "SELECT column_name AS alias_column_name FROM table_name";
$result = mysqli_query($connection, $query);

while ($row = mysqli_fetch_assoc($result)) {
    // Ensure the alias column has a compatible type with the original column
    $aliasColumnValue = (int) $row['alias_column_name']; // Casting to integer type
    // Further processing or output
}
