What are the potential pitfalls of using cryptic column names in PHP database queries and how can they impact code clarity?

Using cryptic column names in PHP database queries can lead to code readability issues and make it difficult for other developers to understand the purpose of the query. To improve code clarity, it is recommended to use descriptive and meaningful column names that clearly indicate the data being retrieved.

// Bad example using cryptic column names
$query = "SELECT col1, col2 FROM table_name";

// Good example using descriptive column names
$query = "SELECT first_name, last_name FROM users";
