What Need Does PHP Fulfill?
There have already been scripting solutions so long as there's been a global Wide Web. Because the have to create sites with dynamic content is continuing to grow recently, so gets the pressure to generate robust environments quickly and efficiently. Although C could be a great solution for creating fast server tools, additionally it is hard to utilize and will easily produce security holes or even carefully deployed. Perl, a language originally developed for text processing naturally met the demand for dynamic Web environments. Easier to deploy safely than C, its slower performance is definitely a lot more than balanced by the comparatively fast development cycle it provides. A lot more useful has been the increasing option of numerous stable code libraries for Perl.
So where does PHP easily fit into? PHP was written specifically for the Web. Most of the problems and issues faced by Web programmers are addressed within the language itself. Whereas a Perl programmer must use an external library or write code to obtain data submitted by an individual of a Website, PHP makes this data automatically available. Whereas a Perl programmer must install modules make it possible for her to create database-driven environments, PHP bundles a robust SQL database library and built-in support for a complete selection of third-party databases. In a nutshell, because PHP has been designed for Web programmers, it includes a group of functions for every typical problem you may encounter, from managing user sessions to handling XML documents.
So, do we need to purchase this simplicity with even slower performance? Never. PHP is made to run as a module with many server applications, meaning that you can find none of the start-up overheads connected with CGI scripts. The truth that many typical tasks are handled by PHP implies that developers are free of reliance on utility libraries that may slow things down.
