If you are a website owner or a web developer, then you must know the role of PHP in development. With PHP 7, there has been significant improvements over the earlier versions and it has also come up with some most attractive features. It is a platform that can deliver powerful applications, from cloud to enterprise applications and from mobile to the web applications. This PHP 7 version has the most powerful impact as it reduces the memory consumption with high improvements in the performance.
PHP development has come up with many new features that can be used for rich application, but are you aware of certain things that you should not do in PHP 7? Here in this blog, we will discuss some of them:
Don’t use Mysql Functions:
Now the time has come that you should stop using mysql _ functions and PHP 7 will remove them altogether from the core and this means that you will have to move to the far better mysql_ functions or switch to even more flexible PDO implementation.
Do not use Pass by Reference Until Needed:
Personally, I recommend not to sue the passing by reference until it is needed. Though at times in certain cases it is useful, but in many others it makes the code difficult to understand and follow and it is specially difficult to predict the result also. Many people have the notion that it makes the codes faster, but some PHP programmers say that it is not true.
Avoid Performing Queries in a Loop:
Performing database queries within a loop is just a waste. It puts much strain on the system and it is likely that you can attain similar results outside the loop. If in case, I face any such situation where this is essential, I solve the issue with two separate queries used to build an array of data and then I loop over the array, so there is no need to perform the queries in the process.
Don’t Trust Any User Input:
Do not blindly trust any user input. It is always a good practice to filter, sanitize, escape and then check and use fallbacks. Usually you may have to face three issues with user data like developers don’t consider every possibility into account, the data may be frequently incorrect and malicious data may be sent intentionally. A well thought out system can help to protect from all these, so ensure to use built in functions and check proper values and other functions while working with databases.

Do not Write Useless Codes:
Many developers do not give importance to writing wasteful codes just because PHP 7 development offers high performance of the website and increased speed. So, PHP developers should not be satisfied with the site simply because they have switched to PHP 7. They should write optimized codes and make sure to load scripts only when needed, concatenate them when possible and write database queries by using caching wherever possible.
