Question

廃止予定：関数eregi（）は、C：\ website \ Web_Intersect_v1.34 \ profile.phpの231行で非推奨になりました。 私はpreg_match ）そしてそれはうまくいきません。コードを動作させるにはどうすればよいですか。

$OSList = array 
(
    // Match user agent string with operating systems 
    'Windows 3.11' => 'Win16', 
    'Windows 95' => '(Windows 95)|(Win95)|(Windows_95)', 
    'Windows 98' => '(Windows 98)|(Win98)', 
    'Windows 2000' => '(Windows NT 5.0)|(Windows 2000)', 
    'Windows XP' => '(Windows NT 5.1)|(Windows XP)', 
    'Windows Server 2003' => '(Windows NT 5.2)', 
    'Windows Vista' => '(Windows NT 6.0)', 
    'Windows 7' => '(Windows NT 6.1)|(Windows NT 7.0)', 
    'Windows NT 4.0' => '(Windows NT 4.0)|(WinNT4.0)|(WinNT)|(Windows NT)', 
    'Windows ME' => 'Windows ME', 
    'Open BSD' => 'OpenBSD', 
    'Sun OS' => 'SunOS', 
    'Linux' => '(Linux)|(X11)',

    'Mac OS' => 'Mac OS', 
    'Search Bot'=>'(nuhk)|(Googlebot)|(Yammybot)|(Openbot)|(Slurp)|(MSNBot)|(Ask Jeeves/Teoma)|(ia_archiver)' 
); 

// Loop through the array of user agents and matching operating systems 
foreach($OSList as $CurrOS=>$Match) { 
    // Find a match 
    if (eregi($Match, $agent)) { 
      break; 
    } else { 
     $CurrOS = "Unknown OS"; 
    } 
} 
$device = "$user_device : $CurrOS";

$agent = $_SERVER['HTTP_USER_AGENT']; 
if (preg_match("/iPhone/", $agent)) { 
$user_device = "iPhone Mobile"; 
} else if (preg_match("/Android/", $agent)) { 
$user_device = "Android Mobile"; 
} else if (preg_match("/IEMobile/", $agent)) { 
$user_device = "Windows Mobile"; 
} else if (preg_match("/Chrome/", $agent)) { 
$user_device = "Google Chrome"; 
} else if (preg_match("/MSIE/", $agent)) { 
$user_device = "Internet Explorer"; 
} else if (preg_match("/Firefox/", $agent)) {
