When it comes to web development, the first choice of both the developers and business owners is always PHP. Most business owners look for a PHP development company when all they want is a website with a competitive edge. Developers love to work with this server-side scripting language because of its features, detailed documentation, huge community support, open-source nature, easy syntax, and it is easy-to-edit and maintenance. Also, PHP often gets updated and improved with more advanced features that help developers to build highly competitive websites. And these are the reasons why some of the most widely used websites like Facebook, Wikipedia, Tumblr, MailChimp, and more run on PHP.
But, even if it comes with so many features and functionalities for the developers, still it is essential to optimise the websites or web applications to boost their performance and speed and to stay a step ahead in the SERPs.
So, here are the best ways to optimise your PHP script and boost your website or web app performance.
Optimising the codes or scripts is the first thing developers must keep in their mind while creating a website or a web app with PHP to ensure a fast and more stable development process. And here are the tips to help the programmers must follow every time they are using PHP as the programming language.
Take advantage of all native PHP functions:
Whenever and wherever required, try to take advantage of all the native functions of PHP instead of writing lengthy functions every time on your own. Take your time to learn how you can use these native PHP functions to achieve the same result. Also, using these functions can help you to write the codes faster, making the development process much more efficient.
Use JSON instead of using XML:
Native PHP functions like json_decide() and json_encode() are remarkably fast and this is why JSON is preferred more than XML. And if still, you are using XML, make sure to parse it with regular expressions instead of DOM manipulation.
Cash in on the caching techniques:
Memcache is specifically used to reduce the database load whereas the bytecode caching engines such as OPcache and APC are good for saving more execution time at the time of script compilation.
Cut out all unnecessary calculations:
When you are using the same variable value multiple times, it is always better to assign the variable name with the value at the beginning of the script and declaring only the variable name wherever required instead of doing the same calculation repeatedly everywhere.
As compared to count(), sizeof(), or strlen(), isset() is a much faster and easier way for determining if a given value is greater than zero or not.
Cut out all unnecessary classes:
If you do not intend to use methods or classes multiple times in a script, then you don’t really have to. You can employ classes in the core file and then can include the class or method name wherever you want. Using the derived classes or methods is always a better option. Also, removing the unnecessary classes or methods is one of the best ways to optimise the script and the end result.
Turn off the debugging notifications:
Alerts can draw attention to bugs or errors and can be displayed along with the coding process. But such alerts can slow down the process and the website as well. Hence, disabling such alerts or notifications from beforehand or turning off the debugging notifications is what you must do to ensure an optimised process and end result.
Close all database connections:
Closing the database connections and unsetting the variables in the codes can save memory. It’s one of the best PHP optimisation tips developers must keep in mind.
Limit the database hits:
Making database queries aggregate reduces the number of hits on the database that again makes things run faster.
Stick to using single quotes:
Try to use single quotes as much as possible instead of using double-quotes. Actually, double quotes drag down the performance level as they check for variables in the codes.
Try to use ‘===’ three equal signs:
As three equal sign checks for only a closed range, it is much faster than ‘==’ or double equal sign for comparison.
Apart from these, some more tips you can keep in your mind are:
- Take advantage of OPcache
- Identify the database delays
- Clean up the filesystem
- Profile your PHP
- Monitor the APIs carefully.
So, these were some of the best ways to optimise your PHP codes as well as the website or web application. If you are a PHP developer and if you often struggle to make your development process faster and your website run more efficiently, then hopefully this article will definitely help you out.
