PHP is one of the most favoured open-source web development languages known today due to its robustness, multi-platform support, and its high-end features. Though it is an easy-to-use language, PHP developers often tend to make certain mistakes that need to be avoided or else these issues may turn into serious logical semantic flaws and can even cause security loopholes into the projects. Want to know more about these mistakes being a PHP developer?
Here’s all about it.
PHP may be a robust scripting language but developers are often seen making these common mistakes while coding with it. Avoiding these is important and here’s what they must avoid from the next time.
Wrong use of the operators:
Using the operators in the wrong way and in wrong places is what developers need to avoid and get careful about it. When you are working with PHP, you need to use ‘==’ that is comparison instead of ‘=’ that is the assignment. Using the wrong one can simply alter the variable value. So, avoid this.
Forgetting to rewrite the URL:
It is imperative to mention clean, relevant, and easy-to-understand URLs in different framework guides like Symfony, Laravel, Zend, etc. URLs with a lot of variables are not acceptable as too many variables can make the URLs illegible.
Using MySQL extension:
Using MySQL is considered as an insecure, unreliable, and outdated way that does not even support the SSL. Using this can display depreciation notices on top of the page that can be accessed anywhere by Google and can expose the sites to misusers. This is why developers should avoid using it and use MySQLi instead as it is more updated, fast, and reliable.
Not using PDO:
PHP Data objects let developers use the object-oriented syntax. This helps to align the codes for the database such as PostgreSQL and MySQL. It is a time-saving feature of PHP that enables the injection of data directly into the objects.
Forgetting to make use of the database caching:
Cache helps to improve the performance of the web application and the database, enhancing the user experience at the same time. Query cache, Memcached, Varnish, Redis, etc., all can be used here.
Errors tell the programmers that there is something wrong with the codes. Suppressing these errors is a wrong way to allow the project to run or go live with those potential bugs and glitches. Also, popping up of those incoherent errors while your website or web app is running can be extremely irritating for the users and customers on the internet. The best practice to handle such issues is by redirecting the errors to an error log. The developers can use the php.ini file for this. But frequent logging can sometimes slow down the web app drastically, especially when there is heavy traffic. So, in that case, an alternative solution can be changing the default error handler or replacing it with another customised one that can end the website or application whenever an error is seen. PHP add-ons like Papertrail, etc., also allow sending these errors to the back-end instead of allowing them to pop-up on the screen, so that these can be grouped and fixed later on.
Remote code execution:
Dynamic calls for remote functions like filesystem calls are simply the open invitations for the hackers to secretly execute the codes on the local server. Calls like fopen(), include(), eval(), fsockopen(), etc., need to be avoided as much as possible if used, developers must follow the right validation for the user inputs.
Identifying or being aware of these few common PHP development mistakes can make sure that all these can be rightly addressed. Avoiding these can help the programmers build a smart and secure web project using this amazingly flawless language, PHP.
