ASP vs PHP

What is ASP and PHP?

ASP is stand for Active Sever Pages while PHP is Hypertext Preprocessor

There are a lot of differences between ASP and PHP.

Cost

To run ASP programs one needs IIS installed on a Windows platform server, which is not free. PHP programs run on Linux, which is free. Even the connectivity of the database is expensive in the case of ASP as MS-SQL is a product of Microsoft that needs to be purchased. PHP generally uses MySQL, which is freely available.

Speed

If we compare the speed of ASP and PHP then PHP has an upper hand. PHP code runs faster than ASP. ASP is built on COM based architecture, which is an overhead for the server whereas PHP code runs in its own memory space.

Platform Compatibility

PHP programs can run on various platforms like Linux, Unix, Windows and Solaris whereas ASP is mainly associated with Windows platforms. However, ASP can run on a Linux platform with ASP-Apache installed on the server.

Additional Costs

Many of the tools used in PHP are free of cost and since PHP is open source a lot of code can be found in open source forums. PHP has inbuilt features like ftp, email from a web page or even encryption mechanisms but in ASP such features are not built in and some additional components are required. Therefore an additional cost is incurred for such components.

Base Language

PHP is based on C++ language and the syntax used in PHP is quite similar to C/C++. C/C++ is still considered the best programming language by many programmers and people who love this language would surely feel more comfortable with the syntax of PHP. ASP on the other hand has a more Visual Basic kind of syntax that again is closely related to only Microsoft products. So, it depends on a person-to-person which language he or she is comfortable

Database Connectivity

PHP, being extremely flexible, can connect to various databases, the most popular being MySQL. ASP mainly uses MS-SQL.
