Are there specific considerations or restrictions when using reserved words as column names in a MySQL database with PHP, especially when deploying on hosting services like Strato?

When using reserved words as column names in a MySQL database with PHP, it is important to properly escape these column names to avoid conflicts and errors. One common way to do this is by enclosing the column names in backticks (`) in SQL queries. This ensures that reserved words are treated as identifiers rather than keywords. When deploying on hosting services like Strato, it is also important to ensure that the database user has the necessary permissions to create, modify, and access tables with these reserved words as column names.

// Example of using backticks to escape reserved words as column names in a MySQL query
$columnName = 'select'; // using 'select' as a column name, which is a reserved word
$query = "SELECT `{$columnName}` FROM tablename";
$result = mysqli_query($connection, $query);

// Checking for errors
if (!$result) {
    die('Error: ' . mysqli_error($connection));
}
