Detect Mobile Device or Desktop in PHP

Nowadays most web projects have a desktop version site as well as a mobile version site. The web interface is available based on the device the user accessed from. When the user visits the website from a mobile device, they need to be redirected to the mobile website version. To load the website version according to the device, you need to detect the device to check whether the site is accessed from a mobile device or desktop.

The mobile detect feature is very helpful to redirect the user to the mobile website and load the mobile version. If you have mobile-only features and want to hide them on a desktop, device detection helps to do it easily. In this tutorial, we will show you how to detect mobile device in PHP and check if the site is accessed from a mobile device with PHP.

Detect Mobile Device using HTTP User Agent in PHP

The easiest way to detect mobile device in PHP is to check if the “mobile” word exists in HTTP User Agent.

• Use the $_SERVER variable with HTTP_USER_AGENT indices to get the User-Agent being used to access the web page.
• Based on the HTTP User Agent, you can detect mobile or desktop devices in PHP.

// Check if the "mobile" word exists in User-Agent 
$isMob = is_numeric(strpos(strtolower($_SERVER["HTTP_USER_AGENT"]), "mobile")); 
 
if($isMob){ 
    echo 'Using Mobile Device...'; 
}else{ 
    echo 'Using Desktop...'; 
}

Detect Device and Platform using HTTP User Agent in PHP

You can use HTTP_USER_AGENT to check device type (mobile/tablet/desktop) and platform (windows/android/iOS) using PHP.

// Check if the "mobile" word exists in User-Agent 
$isMob = is_numeric(strpos(strtolower($_SERVER["HTTP_USER_AGENT"]), "mobile")); 
  
// Check if the "tablet" word exists in User-Agent 
$isTab = is_numeric(strpos(strtolower($_SERVER["HTTP_USER_AGENT"]), "tablet")); 
 
// Platform check  
$isWin = is_numeric(strpos(strtolower($_SERVER["HTTP_USER_AGENT"]), "windows")); 
$isAndroid = is_numeric(strpos(strtolower($_SERVER["HTTP_USER_AGENT"]), "android")); 
$isIPhone = is_numeric(strpos(strtolower($_SERVER["HTTP_USER_AGENT"]), "iphone")); 
$isIPad = is_numeric(strpos(strtolower($_SERVER["HTTP_USER_AGENT"]), "ipad")); 
$isIOS = $isIPhone || $isIPad; 
 
if($isMob){ 
    if($isTab){ 
        echo 'Using Tablet Device...'; 
    }else{ 
        echo 'Using Mobile Device...'; 
    } 
}else{ 
    echo 'Using Desktop...'; 
} 
 
if($isIOS){ 
    echo 'iOS'; 
}elseif($isAndroid){ 
    echo 'ANDROID'; 
}elseif($isWin){ 
    echo 'WINDOWS'; 
}

Mobile Device Detection with custom PHP Library

If you want in-depth detection, the MobileDetect library (MobileDetect.class.php) will help you to detect the mobile device at an advanced level.

The MobileDetect is a PHP class that detects mobile devices and provides device/platform related information.

• This library uses HTTP User-Agent to detect mobile device with PHP.

Use isMobile() function of MobileDetect class to check if the site is accessed from mobile devices.

• Use isTablet() function to detect tablet device in PHP.
• Use isiOS() and isAndroidOS() functions to check device operating system is iOS or Android.

// Include MobileDetect library 
include_once 'MobileDetect.class.php'; 
 
// Create an instance of MobileDetect class 
$mdetect = new MobileDetect(); 
 
if($mdetect->isMobile()){ 
    // Detect mobile/tablet  
    if($mdetect->isTablet()){ 
        echo 'Tablet Device Detected!<br/>'; 
    }else{ 
        echo 'Mobile Device Detected!<br/>'; 
    } 
     
    // Detect platform 
    if($mdetect->isiOS()){ 
        echo 'IOS'; 
    }elseif($mdetect->isAndroidOS()){ 
        echo 'ANDROID'; 
    } 
}else{ 
    echo 'Desktop Detected!'; 
}

Use the following code sample to detect mobile devices and redirect the user to the mobile version of the website.

if($mdetect->isMobile()){ 
    header("Location:https://m.codexworld.com"); 
    exit; 
}

Conclusion

Mobile device detection functionality helps to detect the device type and load the UI based on the screen size. You can also redirect the user to the mobile version based on the device they are accessing the site. This example script helps you to check if visitors visit your site from mobile or tablets or desktop devices and you can redirect the visitor to the suitable website version using PHP.
