#Php code code

Notice that all signs of the PHP code have disappeared.

If you right-click inside your browser and choose View Source (the text may be different depending on the browser you’re using) you can see that the browser is presented with the following: Random Number Generating a random number between 1 and 10: The web server is asked to interpret everything between these two delimiters and convert it to regular HTML code before it sends the web page to the requesting browser. All the browser sees is standard HTML code when it receives the page, hence the name “server-side language.” Let’s look at simple example of some PHP that generates a random number between 1 and 10 and then displays it on the screen: Random Number Generating a random number between 1 and 10: Once the web server has executed the PHP code embedded in a web page, the result takes the place of the PHP code in the page. Whereas client-side languages give you control over how a page behaves once it’s displayed by the browser, server-side languages let you generate customized pages on the fly before they’re even sent to the browser. In contrast, server-side languages like PHP are run by the web server, before sending the web page to the browser. The key difference between JavaScript and PHP is the stage of loading the web page at which these embedded programs are executed.Ĭlient-side languages like JavaScript are read and executed by the web browser after downloading the web page (embedded programs and all) from the web server. When executed, these programs give you greater control over what appears in the browser window than HTML alone can provide. This concept may be a little difficult to grasp, especially if you’ve only ever designed websites using client-side languages like HTML, CSS, and JavaScript.Ī server-side language is similar to JavaScript in that it allows you to embed little programs (scripts) into the HTML code of a web page. Now that you have your virtual server up and running, it’s time to write your first PHP script. SitePoint Premium members get access with their membership, or you can buy a copy in stores worldwide.
