The only problem with this question is that it doesn't include the code within the question
If spam is "Hey, take a look at my code!", then Code Review is meant for spam.
For me, a real spam question would contain less text, and being a lot more unclear. Spam questions would also probably link to an available product instead of some code.
Sure there's some bragging about the code. For this specific question, the line "I can assure this is the best jQuery <=> PHP bridge library there is for PHP 5.3 at the moment." could instead be rephrased to "I believe this is the best (...)".
"Bragging" about code that you have written is not spam.
Even when you're quite sure that your code is really neat, most of us are just human - which means that we can have some lack of self-confidence, in which case it is good to know if others agree with you or not.
