PHP7 which has been released at the end of November 2015 is fast in terms of performance. Hence Php developersall over the world should skip certain unproductive habits that affect the performance of applications they create using PHP.
Points we showcase here will not be apt when attributed to PHP 7 alone, but these points are applicable to all versions of PHP. Developers who are so much obsessed with programming can put these points mentioned in this article into practice, while programming with any of the languages they are used to.
1. Write clean codes
Not only PHP, but all the good programming languages promote the use of clean codes these days. Clean codes bring a lot of readability. It gives immense scope for improvisation whenever necessary.
Many developers have the habit of using one letter variable, and other types of brilliant ideas to boost up the speed of pages while downloading. This practice will mostly end it in the poor readability of codes.
So when creating PHP codes, every developer should define the variables correctly, and stick to the genuine values of object oriented programming. PHP7 or any of its versions will work rapidly, if the developers make use of clean codes.
2. Stop Using MySQL Functions
PHP always comes with plenty of advanced functions, and the database you utilize corresponding to it should be the updated ones. One best instance to the point is the use of mysqli functions with all the advanced PHP versions.
Mysqli supports easy PDO implementation, and much more facilities than mysqul. So developers can produce great outputs, if they make use of mysqli functions with latest PHP versions.

3. Use of Close Tags
Some developers use close tags while concluding PHP files. Most of the WordPress file skip this bad practice. It is not mandatory in PHP, but novice developers still utilize it for keeping the whitespace under control. But modern versions of PHP never highlight the use of closing tags at the concluding portion of files as necessary.
4. Letting of Queries Function in a Loop
Create an array of data, and write two separate Queries instead of letting queries function in a Loop. In some situations the activity of performing the queries in a Loop will bring faster results, but it will only leave your device so strained as well as heated up most times.
WordPress has a method namely get_post_ meta() which will help developers to attain relative meta value. It functions like a cache system, when developers use this method it collects the values from the database and stores it in cache.
Whenever the method is called again and again, it will not look for values from the database,but works by using the values already stored in the cache system. It improves the speed of functions, and limits the load occurs on the CPU, and saves it from over heating. If you make use of ‘Query Monitor’, you can control the functioning of queries in a Loop.
5. Avoid Unnecessary Passing of References
PHP has built in Shuffle() and sorts() methods. When you return a shuffled array it functions to modify these inbuilt functions. Thus the originality of using these functions will be lost. Modifications that are done to the original functions, without any special needs are unacceptable.
In rare cases passing of references will help the programme work rapidly, but it seems to be all the way illogical. All the advanced versions released by PHP are lighting fast, and developers do not have to pass references to improve the functioning of a programme any more.
Conclusion
PHP web developmenthas gone through a lot of flexible modifications recently for promoting advanced programming. Many of the web designers claim that there is nothing new in PHP, since the release of PHP 5, and the recent launch of PHP 7 by the end of November 2015 marked an end to all that claims forever.
