I\u2019ll have a new book finished and ready for you soon: Solving the N+1 Problem in PHP. Although I have written and spoken about the N+1 problem several times over the past few years, this book is an extended disstertation on the topic.
\nDescribing the N+1 problem is one thing, and talking about the solutions in the abstract yet another. But how to diagnose and discover the problem, as well as refactoring strategies to resolve N+1 problems in your codebase? Those are something else, and they are what the new book provides, similar to the strategies I presented in Modernizing Legacy Applications in PHP. At about 40 pages of narrative and code, in many ways the new N+1 book serves as a topic-specific add-on to MLAPHP.
\nSpeaking of which, MLAPHP is getting an update! The update is nothing extensive, mostly typo fixes and a couple of added details, all from attentive and interested readers. Current owners will receive the update for free.
\nSo when will they be completed? Monday. And there\u2019s a special deal involved for the week they\u2019re finished.
\nMLAPHP is just about a year old, so to celebrate this new book, if you purchase both MLAPHP and the N+1 book as a bundle next week, they will each be about 50% off. That\u2019s a total of $23.99 $22.99 (suggested $39.99 $28.99) for both books, with a 45-day money-back guarantee backed by Leanpub.
After the sale week, they\u2019ll go back to their normal prices, so this is your chance to get a bigger bang for your buck. Of course, the new N+1 book is only $5.99 (suggested $7.99), so it\u2019s not exactly a bank-breaker in the first place.
\nMore updates when the new book and the update are finalized!
\nUPDATE (Fri 20 Mar): The bundle is now available at https://leanpub.com/b/mlasn1php. Go get it while you can!
