It's by far the most plausible explanation for your symptoms. Note that this kind of problem is a bit tricky to deal with, because it happens on write-time. So even if you correct the cause of the problem, you also need to go back and manually fix the corrupted data. -- troels

I\'m a Zend Framework user If that's the case, then you have double escaping going on. The data should not contain the slash once it's in the database. The point of adding the slash is to "protect" the data when it's embedded in *the query*. That is also why you don't have to (and indeed should not) unescape anything when reading from the database. The slashes are *only* there because you're embedding data in a query. Compare this with a string literal in php. Given the following: echo "A \"double\" quote"; Running this php code will output: A "double" quote That's because the *data* doesn't contain any slashes. The slashes are there so that the php parser can read the literal string. Once they have been read into memory, the slashes are gone. Same thing with sql. -- troels

[fw-general] Zend_Db_Table with multiple databases
Hi. I'm looking into replacing a legacy system with Zend_Db + subpackages (Zend_Db_Table and friends), but I'm running into some problems. The setup we have is a master/slave. For offloading the main server all read queries are channelled to the slave, while all write queries are sent to the main server. The current library supports this by allowing each method to fetch the appropriate link. From what I can see, there is no direct support for such a thing in Zend_db_Table, but I can see a couple of possible flex points in the framework. Before I start off a tangent myself, I was wondering if anybody else have tried something like this? If not, would ZF be willing to accept patches? Thanks. -- troels

It's a trade off between two types of complexity; coupling on one hand and abstraction on the other hand. You don't want coupling, because it makes it hard to reason about your program, but you don't want too much abstraction either. What is "too much" depends a whole lot on the individual programmer, so it can be tricky to pick an appropriate level. There's a certain class of problems where a global symbol doesn't hurt. This is in places where the language imposes global effects in any case. For example, PHP doesn't allow redefining classes, so therefore the autoloader is inherently global in any case. It's not that a global doesn't add coupling here - it's just that the language designers have already made the choice for you. Everything else is a judgement call. > How do you know when it's ok to use Singletons?

Now you're mixing apples and oranges again. Global symbols do not improve performance. Shared resources improve performance. Globals are just one way to share resources, but it's not the only one. -- troels

Yes, that's one of them. A big problem with singleton is that it does two things. One one hand, it ensures a single instance in the application, and on the other hand it provides a means to share this instance. Those two things do not need to be coupled together. >> You can reuse the same object in other ways than through a global symbol. > > Aren't singleton classes preferred over global variables? Most people would say that, yes. And I agree, but I would really prefer neither. Global variables and singletons and static methods and static variables all share a similarity in that they are globally scoped symbols. That makes all of them suspect. -- troels

This is the only benefit of a singleton. While it's real, it usually doesn't make up for the high level of coupling it incurs. Ultimately it's a judgement call, but most experienced programmers wouldn't use them in this scenario (or at all). > Only thing I really understand that it gets always the same instance of the > class > and does not create new ones. If you don't fully understand the implications of singletons, you should probably avoid them like the plague. If you *do* understand the implications of singletons you *will* avoid them like the plague. -- troels
