Handling ConnectionError exception in php?

You can handle it using try and catch, can't you?

try {
    // perform your curl here
} catch (Exception $ex) {
    // here you have the exception
}

Or check your log on which specific exception is thrown when you get connection refused and put that one instead of the Exception in the catch. But Exception is the one that all extend from so that will catch all exceptions.

it is not catching any exception from this

What exception are you getting? And can you show your exception code handling code?

Show some code please then on what you are trying to do, because I cannot understand the problem.

How do you get an exception then?

while($success2 != 200) { $response2 = curl_exec($ch); $success2 = curl_getinfo($ch, CURLINFO_RESPONSE_CODE); }

Suppose the site is too busy and it sends us connection refused.. The connection was reset.. then what to do in that sitution..

You dont seem to have written any of the code provided by @nakov ?

is there any way to check connection refused or connection reset for demo purpose??

@grgbikash05 demo or not demo:

while($success2 != 200) { 

    try {
       $response2 = curl_exec($ch); 
       $success2 = curl_getinfo($ch, CURLINFO_RESPONSE_CODE); 
    } catch (\Exception $e) {
        // here the exception is CAUGHT :)
    }

}
