Say there is a special PHP function foo($number) that returns double the value of its input. Further, say there is a table that contains the column "number." Is there a way to have the PHP function and SQL query to run together so that I would get the following:
Number | Double
================
1 | 2
5 | 10
While in this simple example column Double can easily be implemented within the SQL statement, answers should cover the more general case of calling any PHP function, as there are many operations that are difficult to impossible in SQL but easy in PHP.
No, since the query results come straight from MySQL. You can apply the function to the result set after you execute your query, either by using a loop or by applying your function to the results using
array_map()function.
