Anyone who has never learned to design web sites will come to a point where we begin to realize the limitations of HTML and client-side scripting languages such as CSS and Javascript. Although programming languages are at the core of web development, but their main function is to control the display of text and graphics only. Because they do not have the ability to manipulate information as needed, or to communicate with web servers, so that can only produce static Web pages.
Well this is where the need for dynamic web pages began to appear. Let's say you want to create a survey to collect information from your web visitors. You could easily create a form with HTML that contains all your questions, and ask your visitors to send the results via email. But to turn raw information into a form that has meaning, then you have to process them manually. The process is very time-consuming.
Fortunately, by using scrip, there is an easier way to gather and evaluate the survey results, or any form. Instead of sending information via email, a script can be designed to capture and store information into a database. Another script will communicate with the database, collecting and classifying information, then display it when there are guests who need a web site. Of course, the script can also display graphs, a percentage to the total, or display the information in any other way you can imagine, automatically, and on demand.
Well, today, more and more web developers are using PHP. That means, you must follow with the main stream with PHP learn how to follow it.
What Is PHP
PHP (PHP Hypertext Preprocessor) is an embedded scripting language on the server side. If we use the colloquial term, perhaps like this: Processor PHP is running on the server (Windows or Linux). When a page that contains PHP, the processor translates and executes all the commands in the page, and then displays the results to the browser as HTML pages biasa.karena this translation occurs on the server, a page written with PHP can be seen with the use of all kinds browser, on any operating system
Like most other scripting languages, PHP can be embedded directly into HTML.
PHP code separated from HTML by Start and End. When a document is parsed, the PHP processor only interprets the marked area only, and displays the results in the same place.
Ironically, PHP also has the ability to almost completely separate code from HTML.
For projects with a larger, this method is ideal because it allows designers to work on the layout of a page without affecting the code PHP.
