Demand of PHP is evident from the fact that the world’s top websites, like Facebook, Google, Wikipedia, and YouTube, are using PHP scripts at the backend. PHP is helpful in developing dynamic websites. It is a server-side scripting language that sends information directly to the server when a user submits a form. Before going towards the step-by-step guide on how to write PHP scripts, I will give you a general overview of PHP. First introduced by Rasmus Lerdorf, PHP is an open-source, server-side general scripting language that has now become a de-facto coding standard in the web development industry. It can be learned easily, and if one is from a coding background, he (or she) will find it very simple. This is why many are using PHP to polish up their entry-level coding skills. PHP runs on different operating systems, like Windows, UNIX, Linux and supports different databases like MySQL, Microsoft Access, and Oracle. PHP can not only collect form data, but it can also create, read, write, delete, and close files on the server. It can be easily embedded in HTML. PHP code is embedded in HTML with tags .
Although, PHP is not a suitable language for development of desktop applications, but it supports some advanced features like PHP-GTK which is basically an extension of PHP. PHP-GTK provides object-oriented user interface. php programming enables you to choose not only the operating system of your choice but also allow you to have choices to use a web server that you are familiar with. It also enables beginners and professionals to write scripts in their own ways as it allows procedural as well as object-oriented programming. PHP not only enables you to output HTML but also lets you include images, PDFs, videos, and sounds. PHP can auto-generate XHTML and XML files.PHP provides support to protocols like LDAP, HTTP, COM, POP3, etc. It also supports WDDX complex data exchange.
