Check if PHP-page is accessed from an iOS device

Solution 1:

Use the user agent from $_SERVER['HTTP_USER_AGENT'], and for simple detection you can use this script:

<?php

//Detect special conditions devices
$iPod    = stripos($_SERVER['HTTP_USER_AGENT'],"iPod");
$iPhone  = stripos($_SERVER['HTTP_USER_AGENT'],"iPhone");
$iPad    = stripos($_SERVER['HTTP_USER_AGENT'],"iPad");
$Android = stripos($_SERVER['HTTP_USER_AGENT'],"Android");
$webOS   = stripos($_SERVER['HTTP_USER_AGENT'],"webOS");

//do something with this information
if( $iPod || $iPhone ){
    //browser reported as an iPhone/iPod touch -- do something here
}else if($iPad){
    //browser reported as an iPad -- do something here
}else if($Android){
    //browser reported as an Android device -- do something here
}else if($webOS){
    //browser reported as a webOS device -- do something here
}

?> 

If you want to know more details of the user device I recommended to use one of the following solutions: http://51degrees.mobi or http://deviceatlas.com

Solution 2:

preg_match("/iPhone|Android|iPad|iPod|webOS/", $_SERVER['HTTP_USER_AGENT'], $matches);
$os = current($matches);

switch($os){
   case 'iPhone': /*do something...*/ break;
   case 'Android': /*do something...*/ break;
   case 'iPad': /*do something...*/ break;
   case 'iPod': /*do something...*/ break;
   case 'webOS': /*do something...*/ break;
}

Solution 3:

function user_agent(){
    $iPod = strpos($_SERVER['HTTP_USER_AGENT'],"iPod");
    $iPhone = strpos($_SERVER['HTTP_USER_AGENT'],"iPhone");
    $iPad = strpos($_SERVER['HTTP_USER_AGENT'],"iPad");
    $android = strpos($_SERVER['HTTP_USER_AGENT'],"Android");
    file_put_contents('./public/upload/install_log/agent',$_SERVER['HTTP_USER_AGENT']);
    if($iPad||$iPhone||$iPod){
        return 'ios';
    }else if($android){
        return 'android';
    }else{
        return 'pc';
    }
}

Solution 4:

$browser = strpos($_SERVER['HTTP_USER_AGENT'],"iPhone");
