The XPertDeveloper blog has shared some micro-optimization tips in a new post to their blog today. It's ten things you can do to squeeze that extra little bit out of your application's performance.
This post covers most performance improvement tips related to PHP coding. While working with small website or project it's ok to ignore these tips, but when you are dealing with large website or project which is going to maintained for long term and which have large number of user base. Developer must have to consider the below tips from the starting of the project.
Their tips include:
- echo is more faster than print
- Always use single quotes for long strings instead of double quotes. Because in double quotes it will search for php variable to evaluate them.
- If you can declare a method as static then let it be
- Try to minimize relative paths for files inclusion.
Keep in mind that these aren't a "silver bullet" for making your application run faster. These sorts of suggestions should only be applied after the major optimizations (caching with something like APC, good application structure) have been put in place. For most of these examples, you'll only really see an improvement if your application makes use of them heavily in a looping structure.
