PHP Timeout Error in multi_curl

[sbutt]

I'm executing this code from: http://de2.php.net/manual/de/function.curl-multi-exec.php

 

<?php 
$connomains = array( 
   "http://www.cnn.com/", 
   "http://www.canada.com/", 
   "http://www.yahoo.com/" 
); 

$mh = curl_multi_init(); 

foreach ($connomains as $i => $url) { 
  $conn[$i] = curl_init($url); 
  curl_setopt($conn[$i], CURLOPT_TIMEOUT, 15);  //added myself
  curl_setopt($conn[$i], CURLOPT_RETURNTRANSFER, TRUE); 
  curl_multi_add_handle ($mh,$conn[$i]); 
} 

// start performing the request 
do { 
  $mrc = curl_multi_exec($mh, $active); 
} while ($mrc == CURLM_CALL_MULTI_PERFORM); 

while ($active and $mrc == CURLM_OK) { 
  // wait for network 
  if (curl_multi_select($mh) != -1) { 
    // pull in any new data, or at least handle timeouts 
    do { 
      $mrc = curl_multi_exec($mh, $active); 
    } while ($mrc == CURLM_CALL_MULTI_PERFORM); 
  } 
} 

if ($mrc != CURLM_OK) { 
  print "Curl multi read error $mrc\n"; 
} 

// retrieve data 
foreach ($connomains as $i => $url) { 
  if (($err = curl_error($conn[$i])) == '') { 
    $res[$i]=curl_multi_getcontent($conn[$i]); 
  } else { 
    print "Curl error on handle $i: $err\n"; 
  } 
  curl_multi_remove_handle($mh,$conn[$i]); 
  curl_close($conn[$i]); 
} 
curl_multi_close($mh); 

print_r($res); 
?> 

 

but getting this error: Curl error on handle 0: Connection time-out after 15996 ms Curl error on handle 1: Connection time-out after 15996 ms Curl error on handle 2: Connection time-out after 15996 ms.

 

my php version: PHP Version 5.2.4

my curl version: curl-7.17.0

 

Could anybody tell me why is this error coming?

 

Surprisingly the above code works fine on PHP Version 5.1.4, and curl-7-15-3

 

thanks in advance.

Just increase the number of seconds for your timeout to something bigger, like:

curl_setopt($conn[$i], CURLOPT_TIMEOUT, 115);

Actually it's not a problem of timeout, because if it is then it should also not work on the other php/curl mentioned version.

Then i think some function you used in the code above may be deprecated in the recent versions of cURL. :'(

Hi,

  I have tried to find out which particular method is depreciated in curl 7.17.0, that I'm using in my code, but no success .

 

Could anybody please help me out?

 

thanks.

In another example code:

 

<?php
// create both cURL resources
$ch1 = curl_init();
$ch2 = curl_init();

// set URL and other appropriate options
curl_setopt($ch1, CURLOPT_URL, "http://slycl1154.st1.spray.net/dev/sbutt/util/overTure.xml");
curl_setopt($ch1, CURLOPT_HEADER, 0);
curl_setopt($ch1, CURLOPT_TIMEOUT, 2);
curl_setopt($ch2, CURLOPT_URL, "http://slycl1154.st1.spray.net/dev/sbutt/util/inkToMe.xml");
curl_setopt($ch2, CURLOPT_HEADER, 0);
curl_setopt($ch2, CURLOPT_TIMEOUT, 2);


//create the multiple cURL handle
$mh = curl_multi_init();

//add the two handles
curl_multi_add_handle($mh,$ch1);
curl_multi_add_handle($mh,$ch2);

$running=null;
//execute the handles
do {
   
curl_multi_exec($mh,$running);
//sleep(3);
echo "Feed :".$running;

} while ($running > 0);
//close the handles
curl_multi_remove_handle($mh,$ch1);
curl_multi_remove_handle($mh,$ch1);
curl_multi_close($mh);

?> 

 

the script just hangs when i run it with specification:

 

PHP Version 5.2.4

curl-7.17.0

 

The strange thing is when i remove the timeouts

curl_setopt($ch1, CURLOPT_TIMEOUT, 2); and curl_setopt($ch2, CURLOPT_TIMEOUT, 2);

the script starts working.

 

The mentioned 2 feeds are very small which obviously require time in milliseconds to load and hence no problem comes.

 

But when i change the same code and include for example *www.cnn.com* as one of my urls then problem starts to appear again even with or without timeouts.

 

Another strange thing is that when i run all these above scenarios with older specification:

PHP Version 5.1.4

curl-7-15-3

 

no problem comes.

Now in the end, could anybody tell me if the problem i have mentioned above is related to specification:

 

PHP Version 5.2.4

curl-7.17.0

 

and if yes then with PHP or CURL?

 

In my opinion it has something to do with the timeout but then in libcurl or php wrapper?

 

thanks.
