ブラウザ名とOSを検出するための簡単なphpスクリプトがあります。Chromeとして表示されるOPERAを除いて、すべてがうまくいきます。これが私のコードです:
<?php
$user_agent = $_SERVER['HTTP_USER_AGENT'];
function getOS() {
global $user_agent;
$os_platform = 'Unknown OS Platform';
$os_array = array (
'/windows nt 6.2/i' => 'Windows 8',
'/windows nt 6.1/i' => 'Windows 7',
'/windows nt 6.0/i' => 'Windows Vista',
'/windows nt 5.2/i' => 'Windows Server 2003/XP x64',
'/windows nt 5.1/i' => 'Windows XP',
'/windows xp/i' => 'Windows XP',
'/windows nt 5.0/i' => 'Windows 2000',
'/windows me/i' => 'Windows ME',
'/win98/i' => 'Windows 98',
'/win95/i' => 'Windows 95',
'/win16/i' => 'Windows 3.11',
'/macintosh|mac os x/i' => 'Mac OS X',
'/mac_powerpc/i' => 'Mac OS 9',
'/linux/i' => 'Linux',
'/ubuntu/i' => 'Ubuntu',
'/iphone/i' => 'iPhone',
'/ipod/i' => 'iPod',
'/ipad/i' => 'iPad',
'/android/i' => 'Android',
'/blackberry/i' => 'BlackBerry',
'/webos/i' => 'Mobile'
);
foreach ($os_array as $regex => $value) {
if (preg_match($regex, $user_agent)) $os_platform = $value;
}
return $os_platform;
}
function getBrowser() {
global $user_agent;
$browser = "Unknown Browser";
$browser_array = array (
'/msie/i' => 'Internet Explorer',
'/firefox/i' => 'Firefox',
'/safari/i' => 'Safari',
'/chrome/i' => 'Chrome',
'/opera/i' => 'Opera',
'/netscape/i' => 'Netscape',
'/maxthon/i' => 'Maxthon',
'/konqueror/i' => 'Konqueror',
'/mobile/i' => 'Handheld Browser'
);
foreach ($browser_array as $regex => $value) {
if (preg_match($regex, $user_agent)) $browser = $value;
}
return $browser;
}
$user_os = getOS();
$user_browser = getBrowser();
$device_details = '<strong>Browser: </strong>' . $user_browser . '<br /><strong>Operating System: </strong>' . $user_os;
print_r($device_details);
echo('<br /><br /><br />' . $_SERVER['HTTP_USER_AGENT']);
?>
Opera の別の正規表現として /OPR/i を追加して $browser_array を変更し、2 つの Opera 正規表現の後に Chrome 正規表現を配置しました。
$browser_array = array (
'/msie/i' => 'Internet Explorer',
'/firefox/i' => 'Firefox',
'/safari/i' => 'Safari',
'/OPR/i' => 'Opera',
'/opera/i' => 'Opera',
'/chrome/i' => 'Chrome',
'/netscape/i' => 'Netscape',
'/maxthon/i' => 'Maxthon',
'/konqueror/i' => 'Konqueror',
'/mobile/i' => 'Handheld Browser'
);
Chrome UA は次のとおりです。
Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.72 Safari/537.36
Opera UA は次のとおりです。
