What is PHP code?

A server-side scripting language used widely for web development, PHP is also used for general-purpose programming. Created in 1994 by Rasmus Lerdorf, PHP originally stood for Personal Home Page whereas it is now a recursive acronym for PHP: Hypertext Preprocessor. The beauty if PHP is that it is easy to use and can be combined with other web development language tools like HTML, HTML5, CMS and web frameworks.

The popularity of PHP is revealed by the statistics put out by the w3techs.com, wherein they mention that 82.5% of all the websites whose server-side programming language is known to them uses PHP. Implemented either as a module on the web server or a CGI (Common Gateway Interface) executable, the PHP code is usually processed by a PHP interpreter. The results of the PHP code that is interpreted and executed is shown by the web server as a generated web page with contents like data, images etc. At times, PHP code is also executed with a command-line interface or CLI. The facts that PHP code can be deployed on any platform or operating system and that it is free, adds on to the popularity of PHP apart from its functionality.

Why scan PHP codes?

With instances of cybercrime rising day by day, confidential data is getting compromised. The cyber world is constantly battling the threats from hackers around the world. This poses a big challenge for software developers and testers and organizations that develop and consume various web or mobile applications. If PHP is used as widely as 82.5% of websites, it becomes very important to use PHP malicious code scannerto ensure that the PHP code is secure, which in turn means that the web application, server, and data is secure from threats of hackers.

Adopting static code analyzer tools saves a lot of time by identifying the vulnerabilities in your PHP code that can be plugged early. And when you see that the scanner can be easily integrated into your development environment, it makes life easier overall for the developer as well as the tester. PHP malicious code scannersare core components of PHP vulnerability management aspect. The vulnerabilities checked by PHP scanners include, but are not limited to:

Reflected or stored cross-site scripting (XSS)

Directory listings

Standard SQL injections

Potentially insecure direct object references

Un-validated redirects

Distrusted SSL Certificates

Each of these vulnerabilities, if not plugged, can become potential threats to the security of your web application, compromising your data and business. When you are aware of the threats and causes, it is but natural to adopt foolproof security measures for prevention and protection. Scanning PHP codes using PHP vulnerability scanner are thus a very important part of PHP code development that cannot be ignored at any cost.

As software developers, we cannot turn a blind eye to the security of our code and applications in today’s world as otherwise we may end up paying a huge price. More so when there are tools available to help us get the best possible secure code out there in the interests of everyone and the world at large.
