本文實例講述了PHP檢測用戶是否關閉瀏覽器的方法。分享給大家供大家參考，具體如下：
1、例子1
echo str_repeat(" ",3000);ignore_user_abort(true); mylog('online');while (true) { /* * 1、程序正常結束 connection_status 0 * 2、點擊瀏覽器“停止”按鈕 connection_status 1 * 3、超時 connection_status 2 */ echo "test<br>/n"; //注意程序一定要有輸出，否則ABORTED狀態是檢測不到的 flush(); sleep(1); if (connection_status()!=0){ mylog('offline'); die('end the script'); }}function mylog($str){ $fp = fopen('e:/abort.txt', 'a'); $str = date('Y-m-d H:i:s').$str."/r/n"; fwrite($fp, $str); fclose($fp);} 2.例子2
function foo() { $s = 'connection_status '. connection_status(); mylog($s);} register_shutdown_function('foo');//script processing is complete or when exit() is calledset_time_limit(10);for($i=0; $i<10000000; $i++) echo $i;function mylog($str){ $fp = fopen('e:/abort.txt', 'a'); $str = date('Y-m-d H:i:s').$str."/r/n"; fwrite($fp, $str); fclose($fp);}
