When the most powerful languages C and Perl are there, how does PHP fit for dynamic websites?
In this World wide web, there are lot of web scripting solutions.
There is great need to create sites with dynamic content in robust environments quickly and efficiently.
C can easily produce security holes if not carefully deployed and it is also hard to work with it, although it can be a great solution for creating fast server tools.
Perl, a language originally developed for text processing naturally met the demand for dynamic Web environments. Much easier to deploy safely than C, its slower performance has always been more than balanced by the comparatively fast development cycle it offers. Even more useful has been the increasing availability of a large number of stable code libraries for Perl.
That is why PHP here fits up. PHP was written especially for the Web. Many of the issues and problems faced by Web programmers are addressed within the language itself. Whereas a Perl programmer must use an external library or write code to acquire data submitted by the user of a Web page, PHP makes this data automatically available. Whereas a Perl programmer must install modules to enable her to write database-driven environments, PHP bundles a powerful SQL database library and provides built-in support for a whole range of third-party databases. In short, because PHP has been created for Web programmers, it has a set of functions for almost any typical problem you might encounter, from managing user sessions to handling XML documents.
PHP is designed to run as a module with many server applications, which means that there are none of the start-up overheads associated with CGI scripts. The fact that many typical tasks are handled by PHP means that developers are freed from reliance on utility libraries that can slow things down.
It is not the case that PHP does not provide libraries, though. Perl has the Comprehensive Perl Archive Network (CPAN), and PHP has the PHP Extension and Application Repository (PEAR)—its own repository of powerful packages that extend PHP's power.
