assign rows from one column to different variables

Good afternoon, I'm a beginner in php and wanted help with a code. I made a query that selects a column and limits 6 rows in descending order, the query worked out fine, however I am having difficulty to proceed. I need now to get the value of EVERY LINE (row) of the selected column and assign them each in a different variable but I do not know if there is a command for it or if I need a logic to do it. If anyone knows what code to assign in different variables each row of the column please respond me!
