A books I remember with gratitude

I got this book some time ago, when still I worked with php. It is a great wrap-up about php good practice with a mashup of techniques about mysql and other ancillary components to php.
It is a good reading and still one of the books I remember with gratitude.
Is the cover picture about turtles crawling somehow hyronical about the slowness of php programmers?
