Both programming languages PHP and ASP are used to develop dynamic database oriented websites. Active Server Pages (ASP) is normally from Microsoft and is used only with Internet Information Server (IIS) that runs on Microsoft Servers also. But on the other hand you can say PHP is platform independent programming languages and can connect with several kinds of databases.
There are a lot of differences between ASP and PHP.
To run ASP.net programs first need to install IIS on a Windows server platform, this is not a free package. PHP programs can run on Linux, which is free package. Even the database connectivity is expensive for ASP, because it require MS-SQL product of Microsoft that needs to be acquired. Same time on the other hand PHP generally uses MySQL for database connectivity, which is freely accessible.
The Simplicity in Coding
PHP codes itself are very light in weight, a contract programmer who begins his career into PHP, does not felt any pressure to look the source code to understand. Whereas In ASP codes are not so easy to quick understand.
PHP generally being extremely flexible as it uses MySQL for database connectivity, which is freely accessible. Same time on the other hand Database compatibility is expensive for ASP, because it require MS-SQL product of Microsoft that needs to be acquired.
General Run Time
If we evaluate the running speed of PHP and ASP then PHP should gets the upper hand. Normally it is viewed that PHP code runs quicker than ASP code. Due to COM based architecture, ASP uses server space to run while PHP code runs on its own inbuilt memory space.
Background Language Support
ASP has a similar like Visual Basic type of syntax that also linked to Microsoft products as well. On the other hand PHP codes are based on generally C++ language and the syntax, which is used in PHP, is quite similar to C/C++ syntax. C/C++ is still considered by maximum software programmer is the finest programming language and people who love C++ language would certainly feel more relaxed with the PHP syntax.
Running Platform Connectivity
PHP codes can run on different platforms like UNIX, Solaris, Linux, and Windows whereas ASP codes are mostly linked with Windows platforms. Though, ASP programs can run on a Linux platform with the help of ASP-Apache installed on the server.
Further Tools Cost
Several tools used in PHP are mostly free of cost in the market and as PHP is open source a lot of codes can be available in open source forums and blogs. PHP has inbuilt attributes like ftp, encryption methods, even email also from a web page but in ASP such attributes are not obtainable and for this reason only some more features are required which are not free that increase the total cost as well.
Larger Applications Support
PHP is just as protected as ASP from coding level. The main difference is only for private data like “social security numbers”; “PIN numbers” etc. ASP is more practicable option. Organizations like government firms normally don’t have much stipulated commercial budgets and looking for required security, they really helpful ASP.net.
At the end, we can make a conclusion that both programming languages have their advantages and disadvantages specific to user requirement. It can be said that both the programming languages have their own significance depending upon the user's requirements and budgets. It is viewed that in any discussion board, ASP.net is similarly capable but many of them suggesting PHP for small business owners those who have a fixed budget and does not required superb security support. PHP cannot provide e-commerce application development, only for them ASP.net will be the best choice.
