How to avoid Common Security Pitfalls & Glitches in PHP Programming

Being the pioneer in simple scripting niche, PHP has been the favorite baby of many developers around the globe for more than a decade now and still retaining the position with equal vigor.

Owing to its flexibility and easy logic implementation options, more than 79.8% of all websites make use of it. This fact simply states why it is so very majestic in grandeur. Builtwith.com shared an info according to which websites using PHP framework technology in the whole world cover a handsome percentage of 39.31. This is much ahead of Ruby on Rails and ASP.NET.

Having said that, we have decided to jot down a few tips, that would help you in avoiding some common pitfalls of PHP programming:

Proper Reporting of Errors:

You need to report your PHP errors properly, starting from spelling errors in your variables to detecting incorrect function usage. Make sure you hide all your errors once your site goes live. By using “set_error_handler”, you can log your errors in a protected file, that will enable you to know what went wrong and when.

Disabling Bad Features:

Features that allow data validation nightmare and create a pathway for bugs to finding their way into scripts, are known as “Bad Features” of PHP. These features were integrated initially by earliest PHP developers to make the development task a little easier; however, these actually opened up avenues for risks of threat and malware. So, make sure you don’t take the easy way available. On the contrary, go for the hard one and keep your system safe.

Validating Inputs:

In addition to escaping characters, another great to way to protect input is to validate it. With many applications, you actually already know what kind of data you are expecting on input. So the simplest way to protect yourself against attacks is to make sure your users can only enter the appropriate data.

Cross Site Scripting (XSS):

A web application works in the concept of accepting data from users, and showing it in an expected way. This also include comments, threads or blog posts that are in the form of HTML code. But, it can be a little risky sometimes to allow HTML as this functionality allows executing JavaScript in unintended ways. Executed JavaScript can actually hijack your cookies which can later be used to render a real account fake and give an illegal user access to the website’s data.

SQL Injection:

SQL injection attacks occur when data goes unchecked, and the application doesn’t escape characters used in SQL strings such as single quotes (‘) or double quotes (“). If these characters are not filtered out, users can exploit the system by making queries always true and thus allowing them to trick login systems.

With more and more advancement in the technology hemisphere and primarily in the web development arena, the need for advanced support comes into the scene. Hope the discussed points will help you avoid the common pitfalls of PHP programming.
