Ce commentaire est de: PHP and PostgreSQL Advanced Web Programming (Paperback)
The first thing that you will notice about this book is that it is littered with coding, grammatical and spelling errors. So much so that after a while you will begin to lose all respect for the writers. Not a good start.
Next, you will realise that the content in this book is quite random. It is apparently "outside of the scope of the book" to discuss very useful string maniplution functions such as "strtr" and "strstr" (& others). Similarly the writer assumes that the code:
is logically equivalent to:
which is just plain wrong (Page 54 & others). This could mislead readers into writing buggy PHP.
Furthermore, the language used is so childish that one must wonder how it was ever published. Often-used superlatives such as "countless," "endless," etc. are very frustrating to read and not even technically accurate in most cases. It is difficult to find concrete examples, but I can guarantee that you will begin to skim-read most of the content in this book to avoid the writers' inaccurate, childish words.
Readers new to databases and coding will find this book a confusing read. Quite complex ideas such as 'function overloading' are somewhat assumed knowledge. On the contrary, very simple concepts such as if/else statements are discussed in inordinate amounts of detail.
Readers experienced with other databases and programming languages will find this book frustrating. The concepts that are covered in detail are generally very simple ones. The more complex ideas discussed in this book are rarely explored in any useful amount of detail.
I still, however, gave this book 2 stars. Some of the content is covered well and I did learn a few useful tricks here & there. It is also quite useful as a reference tool (the index isn't bad) - but beware of the coding errors!
