echo $_SERVER['HTTP_USER_AGENT'];
輸出的是：
Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0 .3497.92 Safari/537.36
我只想知道是哪個瀏覽器發送的，怎麼都列出來了？
<?php if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 8.0")) echo "Internet Explorer 8.0"; else if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 7.0")) echo "Internet Explorer 7.0"; else if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 6.0")) echo "Internet Explorer 6.0"; else if(strpos($_SERVER["HTTP_USER_AGENT"],"Firefox/3")) echo "Firefox 3"; else if(strpos($_SERVER["HTTP_USER_AGENT"],"Firefox/2")) echo "Firefox 2"; else if(strpos($_SERVER["HTTP_USER_AGENT"],"Chrome")) echo "Google Chrome"; else if(strpos($_SERVER["HTTP_USER_AGENT"],"Safari")) echo "Safari"; else if(strpos($_SERVER["HTTP_USER_AGENT"],"Opera")) echo "Opera"; else echo $_SERVER["HTTP_USER_AGENT"]; ?>
這樣就可以了。
這樣就可以了。
