How can PHP functions like MIN and LEAST be utilized to manipulate database values effectively and efficiently?

To manipulate database values effectively and efficiently using PHP functions like MIN and LEAST, you can use them in SQL queries to retrieve the minimum or least value from a set of columns or rows in the database. This can be useful for tasks such as finding the lowest price among different products or selecting the smallest date from a range of dates.

// Example of using MIN and LEAST in a SQL query to retrieve the minimum value from a set of columns

// Example of using LEAST in a SQL query to retrieve the least value among multiple columns
$query = "SELECT LEAST(column1, column2, column3) FROM table_name";
