I want to convert an Object into a String in PHP. Specifically, I'm trying to take a mysql query response, and I'm trying to convert it into something I can write to a file and use later.
Of course, when you try to write an Object to a file, PHP appropriately yells: Catchable fatal error: Object of class DB_result could not be converted to string in .....
Alternatively, if there is some other way of writing the result of a mysql query to a file, that works too. I'm playing around with a home-brewed caching project :)
Maybe serializing? It will take an object/array and convert it to a string (which can then be un-serialized back later)
