Clean and efficient coding technique in PHP
2007-12-13 08:02:00 Well there are lots of discussion regarding what the actual "clean code" is. At the end of the day you can find there are maily two criterion for clean code:1. Efficiency: Does the code run as quickly and efficiently as possible? Does the code make the most of it's objects and variables with maximum reuse and minimal waste?2. Maintainability: Is the code easy to understand for other developers? Is it well planned, logical, well documented, and easy to update?Let's discuss the various elements comprising these two broad points regarding clean code, and example in PHP.One way or another, all pseudo code is eventually converted to machine code. This code will occupy some finite amount of memory. Some languages, such as Java and the .NET Framework first product IL (Intermediary Language) code before producing machine code. In PHP, there are a few key ways to minimize the amount of memory and machine code overhead generated by your application. The best place to start the discussion i...
