php – 连接保持活动的问题

我有一个PHP脚本“A”,它启动另一个PHP脚本“B”,运行长达5个小时.我使用curl函数.但我的问题是脚本“A”不确定是否保持与脚本“B”的连接.我已经更改了max_execution_time,超时,套接字超时等…但没有任何帮助.

我是否需要使用curl或其他东西向脚本“B”发送标题？

$curl_header[] = "Accept: text/xml,application/xml,application/xhtml+xml,text
/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5";
$curl_header[] = "Cache-Control: max-age=0";
$curl_header[] = "Connection: keep-alive";
$curl_header[] = "Keep-Alive: 84600"; 

$url = 'http://test.de/test_B.php';

$ch = curl_init();
curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)');
curl_setopt($ch,CURLOPT_FRESH_CONNECT,true);
curl_setopt($ch,CURLOPT_HTTPHEADER,$curl_header); 
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,300);
curl_setopt($ch,CURLOPT_TIMEOUT,84600);
curl_setopt($ch,CURLOPT_NOSIGNAL,CURLOPT_RETURNTRANSFER,CURLOPT_URL,$url);
$result = curl_exec($ch);
$curl_errno = curl_errno($ch);
curl_close($ch);
