[php] PHP - Check if the page run on Mobile or Desktop browser

In my PHP page I should display two different text contents according to whether the page run under mobile or desktop browser. Is there a way to perform this control in PHP?

You can do it manually if you want.

Reference: http://php.net/manual/en/function.get-browser.php

preg_match('/windows|win32/i', $_SERVER['HTTP_USER_AGENT'])

preg_match('/iPhone|iPod|iPad/', $_SERVER['HTTP_USER_AGENT'])

You can even make it a script

$device = 'Blackberry'

preg_match("/$device/", $_SERVER['HTTP_USER_AGENT'])

Here is somewhat of a small list

                        '/windows nt 6.2/i'     =>  'Windows 8',
                        '/windows nt 6.1/i'     =>  'Windows 7',
                        '/windows nt 6.0/i'     =>  'Windows Vista',
                        '/windows nt 5.2/i'     =>  'Windows Server 2003/XP x64',
                        '/windows nt 5.1/i'     =>  'Windows XP',

                        '/windows me/i'         =>  'Windows ME',
                        '/win98/i'              =>  'Windows 98',
                        '/win95/i'              =>  'Windows 95',
                        '/win16/i'              =>  'Windows 3.11',
                        '/macintosh|mac os x/i' =>  'Mac OS X',
                        '/mac_powerpc/i'        =>  'Mac OS 9',
                        '/linux/i'              =>  'Linux',
                        '/ubuntu/i'             =>  'Ubuntu',
                        '/iphone/i'             =>  'iPhone',
                        '/ipod/i'               =>  'iPod',
                        '/ipad/i'               =>  'iPad',
                        '/android/i'            =>  'Android',
                        '/blackberry/i'         =>  'BlackBerry',
                        '/webos/i'              =>  'Mobile'

Browsers

                        '/msie/i'       =>  'Internet Explorer',
                        '/firefox/i'    =>  'Firefox',
                        '/safari/i'     =>  'Safari',
                        '/chrome/i'     =>  'Chrome',
                        '/opera/i'      =>  'Opera',
                        '/netscape/i'   =>  'Netscape',
                        '/maxthon/i'    =>  'Maxthon',
                        '/konqueror/i'  =>  'Konqueror',
                        '/mobile/i'     =>  'Handheld Browser'

There are many great open source projects that make detection a lot easier. To name two:

1. PHP mobile detect
2. WURFL

This script should work:

<?php

        $useragent=$_SERVER['HTTP_USER_AGENT'];

        }
        else{
           // echo "desktop";
        }
?>

I came across it here: http://detectmobilebrowsers.com/ .

<?php //-- Very simple variant
$useragent = $_SERVER['HTTP_USER_AGENT']; 
$iPod = stripos($useragent, "iPod"); 
$iPad = stripos($useragent, "iPad"); 
$iPhone = stripos($useragent, "iPhone");
$Android = stripos($useragent, "Android"); 
$iOS = stripos($useragent, "iOS");
//-- You can add billion devices 

$DEVICE = ($iPod||$iPad||$iPhone||$Android||$iOS||$webOS||$Blackberry||$IEMobile||$OperaMini);

if ($DEVICE !=true) {?>

<!-- What you want for all non-mobile devices. Anything with all HTML codes-->

<?php }else{ ?> 

<!-- What you want for all mobile devices. Anything with all HTML codes --> 
<?php } ?>

I used Robert Lee`s answer and it works great! Just writing down the complete function i'm using:

function isMobileDevice(){
    $aMobileUA = array(
        '/iphone/i' => 'iPhone', 
        '/ipod/i' => 'iPod', 
        '/ipad/i' => 'iPad', 
        '/android/i' => 'Android', 
        '/blackberry/i' => 'BlackBerry', 
        '/webos/i' => 'Mobile'
    );

    //Return true if Mobile User Agent is detected
    foreach($aMobileUA as $sMobileKey => $sMobileOS){
        if(preg_match($sMobileKey, $_SERVER['HTTP_USER_AGENT'])){
            return true;
        }
    }
    //Otherwise return false..  
    return false;
}
