本文实例讲述了PHP检测用户是否关闭浏览器的方法。分享给大家供大家参考，具体如下：
1、例子1
echo str_repeat(" ",3000);ignore_user_abort(true); mylog('online');while (true) { /* * 1、程序正常结束 connection_status 0 * 2、点击浏览器“停止”按钮 connection_status 1 * 3、超时 connection_status 2 */ echo "test<br>/n"; //注意程序一定要有输出，否则ABORTED状态是检测不到的 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);}
