Curl Timeout Time setting

The example in this article describes the Curl Timeout setting method in PHP. Share to everyone for your reference. The implementation method is as follows:

There are many ways to access HTTP, such as curl, Socket, file_get_contents ().
When you access HTTP, you need to consider the issue of timeouts.

Curl accesses http:

CURL is a common Lib library that accesses the HTTP protocol interface, with high performance, and some features that are supported concurrently.
curl_setopt ($ch, opt) can set some timeout settings, mainly including:
① (important) Curlopt_timeout sets the maximum number of seconds that curl is allowed to execute.
② (important) Curlopt_timeout_ms sets the maximum number of milliseconds that curl allows to execute.
(added in Curl 7.16.2.) Available from PHP 5.2.3)
③curlopt_connecttimeout the time to wait before initiating the connection, or infinite wait if set to 0.
④curlopt_connecttimeout_ms the time, in milliseconds, that the connection is trying to wait.  If set to 0, the wait is infinite. (added in Curl 7.16.2.) Available starting from PHP 5.2.3)
⑤curlopt_dns_cache_timeout sets the time to save DNS information in memory by default of 120 seconds.

1. Curl Normal second timeout:

Copy CodeThe code is as follows: $ch = Curl_init ();
curl_setopt ($ch, Curlopt_url, $url);
curl_setopt ($ch, curlopt_returntransfer,1);
curl_setopt ($ch, curlopt_timeout,60); You only need to set the number of seconds to
curl_setopt ($ch, Curlopt_httpheader, $headers);
curl_setopt ($ch, curlopt_useragent, $defined _vars[' http_user_agent ');

2. Curl normal second time-out use:

Copy CodeThe code is as follows: curl_setopt ($ch, curlopt_timeout,60);

3. If you need to perform a millisecond timeout, curl needs to increase:

Copy CodeThe code is as follows: curl_easy_setopt (curl, curlopt_nosignal,1l);
Or
curl_setopt ($ch, curlopt_nosignal,true);//support for millisecond-level timeout settings

I hope this article is helpful to everyone's PHP programming.

function Curl_post3 ($url, $postData) {
   $postData = Json_encode ($postData);
   $curl = Curl_init ();  Initialization
   curl_setopt ($curl, Curlopt_url, $url);  Set URL
   curl_setopt ($curl, curlopt_httpauth,curlauth_basic);  Setting HTTP authentication Methods
   curl_setopt ($curl, curlopt_timeout,3);   You only need to set the number of seconds to
   curl_setopt ($curl, curlopt_returntransfer,1);  Set the return mode of the information obtained by curl_exec
   curl_setopt ($curl, curlopt_post,1);  Set Send as POST request
   curl_setopt ($curl, Curlopt_postfields, $postData);  Set the data for the post

   curl_setopt ($curl, Curlopt_httpheader, Array (
         ' Content-type:application/json ',
         ' Content-length: '. Strlen ($postData))
   );

   $result = curl_exec ($curl);
   Curl_close ($curl);
   Return Json_decode ($result, true);
}
