Mobile Device Detection and Redirection Script Using a PHP Home Page

Mobile/Handheld Device Browsers(Agents) are competing with IE, Firefox, and other popular classic browsers in a strong way. To be sure your site is ready and sized correctly you may want to detect and serve up alternate design/layouts for popular sizes and resolutions in which those devices view web pages.

You can use this PHP code on your homepage to run mobile device detection and redirection. Target any or all devices that may come into play as popular web browsing tools.

Your server must be able to process PHP for this to work for you. Server Side detection is probably the most reliable way to detect for mobile devices. There are also other methods which I will discuss in an upcoming video tutorial.

Tip - You can choose to have PHP output an alternate CSS style sheet string, instead of having multiple home pages, you can have one hompage with several different style sheets to set up the layout/sizing. Style sheet would change depending on user agent. So there are many ways to address these issues if you are concerned about mobile users viewing your pages.

// Simply find the device OS or browser label and place conditionals as needed
// Put browser name into local variable

if (preg_match("/iPhone/"$agent)) { 
// Apple iPhone Device
    // Send them to iphone sized homepage for mobile
header("location: iphone_home.html"

} else if (
preg_match("/android/"$agent)) { 
// Google Device using Android OS
    // Send them to android sized homepage for mobile
header("location: android_home.html"
<h2>This is my regular homepage for people not using the devices defined in my script.</h2>
<h3>If none of the user agents defined are detected, this page will display by default.</h3>
<strong>You are viewing this page using:</strong><br />
<em><?php echo $agent?></em>

You may need to research what popular agent names are for devices that may view your pages. I think mine are correct for iPhone and Android. But look into it yourself.

Until everything is universal we have to adapt our pages. Pretty soon we will be able to make 100% width layouts for all browsers and devices, as the resolutions for these devices grows to higher resolutions. But for now many devices view at a much smaller resolution than your typical computer monitor that is sold today in stores, so we may have to resize our websites.
