Comment détecter en PHP le navigateur utilisé ?
Vous trouverez ci-joint un script fort utile.
function recupererBrowser()
{
$u_agent = $_SERVER['HTTP_USER_AGENT'];
$bname = 'Inconnu';
$platform = 'Inconnu';
$version= "";
if (preg_match('/linux/i', $u_agent)) {
$platform = 'linux';
}
elseif (preg_match('/macintosh|mac os x/i', $u_agent)) {
$platform = 'mac';
}
elseif (preg_match('/windows|win32/i', $u_agent)) {
$platform = 'windows';
}
if(preg_match('/MSIE/i',$u_agent) && !preg_match('/Opera/i',$u_agent))
{
$bname = 'Internet Explorer';
$ub = "MSIE";
}
elseif(preg_match('~MSIE|Internet Explorer~i', $u_agent) || (strpos($u_agent, 'Trident/7.0; rv:11.0') !== false)) {
$bname = 'Internet Explorer';
$ub = "MSIE";
}
elseif(preg_match('/Firefox/i',$u_agent))
{
$bname = 'Mozilla Firefox';
$ub = "Firefox";
}
elseif(preg_match('/Chrome/i',$u_agent))
{
$bname = 'Google Chrome';
$ub = "Chrome";
}
elseif(preg_match('/Safari/i',$u_agent))
{
$bname = 'Apple Safari';
$ub = "Safari";
}
elseif(preg_match('/Opera/i',$u_agent))
{
$bname = 'Opera';
$ub = "Opera";
}
elseif(preg_match('/Netscape/i',$u_agent))
{
$bname = 'Netscape';
$ub = "Netscape";
}
$known = array('Version', $ub, 'other');
$pattern = '#(?<browser>' . join('|', $known) .
')[/ ]+(?<version>[0-9.|a-zA-Z.]*)#';
$i = count($matches['browser']);
if ($i != 1) {
if (strripos($u_agent,"Version") < strripos($u_agent,$ub))
$version= $matches['version'][0];
else
$version= $matches['version'][1];
}
else
$version= $matches['version'][0];
if ($version==null || $version=="") {$version="?";}
return array(
'userAgent' => $u_agent,
'name' => $bname,
'version' => $version,
'platform' => $platform,
'pattern' => $pattern
);
}
comment utiliser cette fonction ?
Cette fonction retourne un tableau : son utilisation est donc simple.
Par exemple :
$browser = recupererBrowser();
if ($browser ['name'] == "Internet Explorer") {
// faire quelque chose
}
