multi curl - mCURL and Timeout in PHP5

[sbutt]

Hello Guys,

              I have heard that in php5 there is a built in support for mCURL or in other words it is possible to open multiple parallel connections with different feeds/urls?

Now if the above is true then somebody please also tell me if it is possible to set a timeout (in millisecond) for each single connection as opposed to set a global timeout connection for all the feeds?

 

 

In Nutt-shell, I want to find out, how this mCURL feature (if possible) handles timeouts on a single feed level?

 

Any small code snippet help would be really appreciated.

 

Thanks.

Hmmm, possibly use curl_setopt() with the CURLOPT_TIMEOUT option.

Thanks for your reply, but could you please write me a small code snipped with more than 1 parallel connections and timeout(in millisecond) for each connection set seperatly, using mcurl? 

 

thanks in advance.

It can't be set in milliseconds, only seconds.

 

As for a code snippet, have you read the manual?  There's a good example there.

Thank you indeed for your help!

 

Have you by any chance heard of 'curl_easy_setopt()', becuase it has this parameter 'CURLOPT_TIMEOUT_MS' that can be used to provide timeout in millisecond.

 

But when i do that i get the error : Fatal error: Call to undefined function curl_easy_setopt() ..

 

my current curl version is: curl=/opt/curl-7-15-3.

 

I tried to find out curl release verion that contains curl_easy_setopt() but no success

That version is too old, you'd need version 7.16.2 (I got this info from the cURL website)

that's correct that 7.17.0, is the most recent version but it would be nice (just out of curiosity!) to know in which curl version 'cury_easy_setopt()' was introduced or in other words with which i can use: curl_easy_setopt($ch1, CURLOPT_TIMEOUT_MS, 0);'

 

Again it's just out of curiosity!

That's what I gave you... 7.16.2  I never mentioned the latest version.

Hi Folks,

          I'm using PHP 5.2.4 with curl-7.17.0 patch. Now when I run this following small code snippet, 

 

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

// set URL and other appropriate options
curl_easy_setopt($ch1, CURLOPT_URL, "http://www.example.com/");
curl_easy_setopt($ch1, CURLOPT_TIMEOUT, 5);
curl_easy_setopt($ch1, CURLOPT_HEADER, 0);

curl_setopt($ch2, CURLOPT_URL, "http://www.php.net/");
curl_setopt($ch2, CURLOPT_TIMEOUT, 5);
curl_setopt($ch2, CURLOPT_HEADER, 0);


//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,$running);
if($running == 0){
echo "Suleman";    
echo "||";
echo $running;
}
} while ($running > 0);

//close the handles
curl_multi_remove_handle($mh,$ch1);
curl_multi_remove_handle($mh,$ch2);
curl_multi_close($mh);

?> 

 

I get this error: Fatal error: Call to undefined function curl_easy_setopt() ..at line 7.

 

Now could anybody please tell me how can i use 'curl_easy_setopt()' function with "CURLOPT_TIMEOUT" option?

 

The default curl_setopt() method with simple timeout param provides timeout value only in seconds, where as i want to set the value for the timeout in milliseconds. And i'm opening parallel connections to the urls (multi curl).

 

thanks.

There's no PHP function called curl_easy_setopt().

 

That's what the problem is.
