What we can do:
PHP : Hypertext Preprocessor, an open source, server-side, HTML embedded scripting language used to create dynamic Web pages.
In an HTML document, PHP script (similar syntax to that of Perl or C) is enclosed within special PHP tags. Because PHP is embedded within tags, the author can jump between HTML and PHP (similar to ASP and Cold Fusion) instead of having to rely on heavy amounts of code to output HTML. And, because PHP is executed on the server, the client cannot view the PHP code.
PHP can perform any task that any CGI program can do, but its strength lies in its compatibility with many types of databases. Also, PHP can talk across networks using IMAP, SNMP, NNTP, POP3, or HTTP.
Advantage of web development using PHP.
Open source: It is developed and maintained by a large group of PHP developers, this will helps in creating a support community, abundant extension library.
Speed: It is relative fast since it uses much system resource.
Easy to use: It uses C like syntax, so for those who are familiar with C, it’s very easy for them to pick up and it is very easy to create website scripts.
Stable: Since it is maintained by many developers, so when bugs are found, it can be quickly fixed.
Powerful library support: You can easily find functional modules you need such as PDF, Graph etc.
Built-in database connection modules: You can connect to database easily using PHP, since many websites are data/content driven, so we will use database frequently, this will largely reduce the development time of web apps.
Can be run on many platforms, including Windows, Linux and Mac, it’s easy for users to find hosting service providers.
