PHP Interview in questions and answers

Someone Andrey Shevchenko compiled, structured and released in the form of a free PDF book a list of questions that can be met (and are most often found) by any PHP programmer at the most standard interview. Moreover, each question has a sufficiently detailed answer.

Scrolling the book will be useful to any PHP programmer who plans to be interviewed soon, or to people interviewing applicants.
