How PHP-CGI and PHP-FPM distinct from each other?

 PHP-CGI (Common Gateway Interface) is a program that creates to exchange data to connect with different applications. CGI scripts should be written in various programming languages i.e. PHP, Python, Perl, etc. You can also find directories easily if the CGI is installed on the server. 

 Benefits of CGI

•  It can work with any type of web server.

•  It does not kick you back until you restart the web browser while making changes in the php.ini file.

•  It provides the best security system in comparison with other options

Demerits of CGI

•  The performance is a bit disappointing for heavy and busier websites.

• The page takes more time to load.

• It is the oldest and traditional way of doing server-side PHP.

• It consumes a lot of memory to run the program.

PHP-FPM The updated version of CGI is FPM (FastCGI Process Manager). The functionality and features are a little bit change in comparison with old CGI. The major advantage of FPM is reducing the page loading time and easily handles the server load. FPM interface is best for the server like Apache and Nginx. Some eminent features of PHP-FPM are as follows:-

•  In case of accidental opcode cache destruction, you can restart it easily

•  It accelerates uploading speed.

• Standard error and standard output logging.

Benefits of FPM

•  It is the modern approach to run the applications inefficient way.

•  Less memory space is required.

• Reload the page in no time.

• Graceful performance for high traffic websites.

• No restart requires while configuring the program.

Demerits of FPM

•  The security system is weaker in comparison with PHP-CGI.

• A high-end configuration is required to run the application.

Which is more suitable PHP-CGI or PHP-FPM?

 After understanding all the merits, demerits, and features of both the term, you should know their working process. It helps you in taking the decision that you have to hand-picked for the development of your website. But for this you have to consider some factors which are given below:-

 If you are creating a simple and light website then you should go with PHP-CGI otherwise for heavier and busiest websites PHP-FPM is best.

 If you are looking for a high-security website then PHP-CGI is the better option. But, if you choose PHP-FPM then you have to compromise with some security issues.

 PHP-CGI consumes more space in comparison with PHP-FPM.

 If you are making changes from time to time then PHP-FPM becomes your choice.

Finally, in my point of view, PHP-FPM is the better bet for all types of Websites because it comes up with updated technology and value-added features.
