In PHP, what are some considerations for naming conventions when it comes to table entities and column names?

When naming tables and columns in a database, it is important to follow a consistent naming convention to make the code more readable and maintainable. One common convention is using lowercase letters and underscores to separate words in table and column names. Additionally, it is recommended to use descriptive and meaningful names that accurately represent the data stored in each table and column.

// Example of naming convention for table entities and column names
$tableName = "users";
$columnName = "first_name";
