And, if you have multiple versions of a single browser—like Firefox 3.6.3 for testing with older Linux-based systems and the most current version (14something-or-other as of late), they each have a different JavaScript installation.Įven though JavaScript doesn’t get updated very often, those multiple installations usually translate into multiple versions of JavaScript, because JavaScript isn’t a product that is distributed by a central organization to browser developers. Add Chrome or Opera to the mix, and you’ve got a few more installations. Suppose that you have Internet Explorer and Firefox you’ve got the JavaScript installation that came with Internet Explorer and the one that came with Firefox. Think about it: if JavaScript is built in to your browser, and you have more than one browser, you actually have multiple installations of JavaScript on your computer. UNDER THE HOOD: You Probably Have Multiple Versions of JavaScript Already!

OPENING A PHP FILE IN CHROME UPGRADE

Just as you can’t upgrade your HTML installation outside of your browser, you can’t upgrade your JavaScript installation outside of your browser.

OPENING A PHP FILE IN CHROME DOWNLOAD

In fact, if a new version of JavaScript were to appear—something that rarely happens these days—you’d need to download a new version of your browser to get that version of JavaScript. In other words, support for JavaScript is part and parcel of your web browser. Whether it was simple phone number validation, more advanced jQuery functions that turned boring gray boxes into animated buttons and elements into tabs, or even the new HTML5 canvas object, within which you could build entire JavaScript-based 3D games, your pages suddenly had new life with JavaScript.īut just as with HTML and CSS, JavaScript is at heart a web technology, and even more specifically, a browser-based technology. Suddenly, you weren’t limited to elements that never moved and text that never changed. Next up in the pantheon of web technologies that every designer and fledgling programmer needs to learn: JavaScript.

JavaScript Adds Complexity, but Not Software Again, no extra software needed.Īt this point, even though you’re using only two technologies—HTML and CSS—you need only a single program to handle those technologies: the web browser. That’s because, once again, the web browser is completely capable of not just rendering HTML, but applying all those CSS styles to the page, too. You might even have a few style sheets for the benefit of people viewing your website on mobile devices or printing out a page: īut you can still double-click that HTML file, and your browser knows what to do (see Figure 1-2). Then, at some point, some well-meaning web designer slapped your hand and insisted that you start writing all your CSS in external style sheets, and referencing those files in the head of your HTML, like this: Using the style attribute and tags in your HTML document, you could change fonts, add striping to your table rows, and generally spice up otherwise boring text. If you keep thinking back, you probably added some styling to your HTML pages. No extra software or configuration is necessary. So get going there’s no reason to leave your users with passive HTML pages any longer.įigure 1-1. Web browsers know all they need to know in order to load and display an HTML page. PHP lets you listen carefully to your users and say something back.

With PHP, you become an active participant in your web pages. Throughout the process, you’ll begin taking control. Not only that, you’ll run your script, upload it to your web server, and access your script with a web browser…and that’s all in the first two chapters! Don’t worry it’s amazingly easy to write your first program in PHP.

OPENING A PHP FILE IN CHROME INSTALL

You need to become familiar with PHP itself, and the best way to do that is to install PHP on your own computer as well as becoming familiar with how PHP runs on a remote web server. And because you’re just working in text, there’s not a lot you have to do to get going as a PHP programmer. PHP is ultimately just text that is taken by your web server and turned into a set of commands and information for your web browser.
