php send curl request and wait for the response
提问by bart2puck
I am sending a curl request to a server that needs a few seconds to process the request and spit out a response. I believe my php script is continuing on and not waiting, therefore my foreach loop based on the response is spitting out 0 results. How can i wait for the curl transaction to complete before moving on and processing data?
我正在向服务器发送 curl 请求，该服务器需要几秒钟来处理请求并发出响应。我相信我的 php 脚本正在继续而不是等待，因此我基于响应的 foreach 循环吐出 0 个结果。在继续处理数据之前，如何等待 curl 事务完成？
$curl = curl_init();
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($curl, CURLOPT_USERPWD, "admin:password");
curl_setopt($curl, CURLOPT_URL, "http://server/r/?dst_user__substr='user'");
curl_setopt($curl, CURLOPT_VERBOSE, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$ret = curl_exec($curl);
$result = json_decode($ret,true);
<<<<I need to wait until transaction is complete here>>>>
foreach ($result['data'] as $key => $value)
{
//process data from $result
}

curl is blocking, which means that:
curl 正在阻塞，这意味着：
$result = json_decode($ret,true);
foreach ($result['data'] as $key => $value)
{
//process data from $result
}
won't execute until:
不会执行，直到：
$ret = curl_exec($curl);
is complete. You can check for errors and other issues using curl_error() and by checking the HTTP response code with curl_getinfo().
已完成。您可以使用 curl_error() 并使用 curl_getinfo() 检查 HTTP 响应代码来检查错误和其他问题。

This is really weird ! , it shouldn't happen like what you are getting. But anyways try like this..
这真的很奇怪！，它不应该像你得到的那样发生。但无论如何尝试这样..
Get a httpresponse code and then check up...
获取一个 httpresponse 代码，然后检查...
$curl = curl_init();
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($curl, CURLOPT_USERPWD, "admin:password");
curl_setopt($curl, CURLOPT_URL, "http://server/r/?dst_user__substr='user'");
curl_setopt($curl, CURLOPT_VERBOSE, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$ret = curl_exec($curl);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if($httpcode==200)
{
$result = json_decode($ret,true);
foreach ($result['data'] as $key => $value)
{
//process data from $result
}
}
