How to determine whether the page is closed in php: You can use the connection_status() function to determine. If the function returns 0, it means the connection was operating normally; if it returns 1, it means the connection was terminated by user or network error.

Possible values that can be returned:
0 - CONNECTION_NORMAL - Connection operation OK
1 - CONNECTION_ABORTED - Connection terminated by user or network error
2 - CONNECTION_TIMEOUT - Connection timed out
3 - CONNECTION_ABORTED & CONNECTION_TIMEOUT
Code implementation:
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); }
