php curl检查在查询之前是否可以访问url

Question

We're having problems with an api we are using.

Here is the code we're using (naming no names on the api front)

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://apiurl.com/whatever/api/we/call');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$ch_output = curl_exec($ch);
curl_close($ch);

This response times out, but not for ages. This is hideously slowing down our web app, and as such further code breaks because of the bad return value. This I can fix, however the response timeout I don't know how to fix. Is there any way to quickly see if a url is "responding" (e.g. something like ping in terminal) before trying to do a curl request?

Thank you.

Answer 1

Do you mean usingcurl_setopt($ch,CURLOPT_CONNECTTIMEOUT,NUMERIC_TIMEOUT_VALUE);to set the timeout?
