Richard Davey, after spending many an hour working on a PDO SQLite bit of functionality for his latest application, has come to one conclusion - "the PDO SQLite blob support is totally borked".
I really don't know why, or what is going on, but after spending hours trying various code permutations I'm just not getting anywhere. I tried asking on php_general to no avail, so I consider this blog entry my last ditch attempt to get someone to shed some light on this issue before I give-in and ditch PDO for good.
His mission was to store an image in the database, but everything he tried just didn't seem to work out. After partial image storage and parameters being ignored, he's still at a loss as to how to get his (seemingly) simple quest solved. The only comment so far, though, hasn't seemed to help much - he's even opened a bug report upon Wez Furlong's request.
