$browser = Array (' Lynx ', ' mosaic ', ' AOL ', ' opera ', ' Java ', ' Macweb ', ' webexplorer ', ' omniweb ');
for ($i = 0; $i <= 7; $i + +) {
if (Strpos ($agent, $browsers [$i])) {
$browser = $browsers [$i];
$browserver = ";
}
}
if (Ereg (' Mozilla ', $agent) &&!ereg (' Msie ', $agent)) {
$temp = Explode (' (', $agent);
$part = $temp [0];
$temp = explode ('/', $part);
$browserver = $temp [1];
$temp = Explode (' ', $browserver);
$browserver = $temp [0];
$browserver = Preg_replace ('/([D.] +)/', ' \1 ', $browserver);
$browserver = $browserver;
$browser = ' Netscape Navigator ';
}
if (Ereg (' Mozilla ', $agent) && ereg (' opera ', $agent)) {
$temp = Explode (' (', $agent);
$part = $temp [1];
$temp = Explode (') ', $part);
$browserver = $temp [1];
$temp = Explode (' ', $browserver);
$browserver = $temp [2];
$browserver = Preg_replace ('/([D.] +)/', ' \1 ', $browserver);
$browserver = $browserver;
$browser = ' opera ';
}
if (Ereg (' Mozilla ', $agent) && ereg (' Msie ', $agent)) {
$temp = Explode (' (', $agent);
$part = $temp [1];
$temp = explode ('; ', $part);
$part = $temp [1];
$temp = Explode (' ', $part);

$browserver = Preg_replace ('/([D.] +)/', ' \1 ', $browserver);
$browserver = $browserver;
$browser = ' Internet Explorer ';
