Data Structures for PHP 7
An extension providing efficient data structures for PHP 7
An extension providing specialized data structures as efficient alternatives to the PHP array. Highlights the API, performance and other benefits. PHP has one data structure to rule them all. The array is a complex, flexible, master-of-none, hybrid data structure, combining the behaviour of a list and a linked map. But we use it for everything, because PHP is pragmatic: “dealing with things sensibly and realistically in a way that is based on practical rather than theoretical considerations”. ... -

The Art of Programming
A collection of practical tips can be found at the bottom of this page
The Art of Programming (Second Edition) is a curated collection of programming problems and solutions originally derived from the Microsoft 100 Interview Questions blog series, later refined into a long-running tutorial and ultimately a published book.
