fetch multiple contents with time out using curl with php mutitreading
this prgm used to fetch the contents from other servers .... wil set the sleeping time and and will see the time taken and how to fetch ,,, by using curl with php mutitreading
<style type="text/css">
<!--
.style2 {color: #FF0000; font-style:oblique; font-size:24px;}
-->
</style>
<?php
function addHandle(&$curlHandle,$url)

curl_setopt($cURL, CURLOPT_URL, $url);
curl_setopt($cURL, CURLOPT_HEADER, 0);
curl_setopt($cURL, CURLOPT_RETURNTRANSFER, 1);
curl_multi_add_handle($curlHandle,$cURL);
return $cURL;
}
//execute the handle until the flag passed to function is greater then 0
function ExecHandle(&$curlHandle)
{
$flag=null;
do {
curl_multi_exec($curlHandle,$flag);//fetch pages in parallel
} while ($flag > 0);
}

hit multiple times on the target address using CURL in php multi treading .....
this program used to hit the target ftp/http/https........hit at multiple times... will getta response from multiple times.....i hope this is example useful for u....
example:-
<?php
error_reporting(0);
// create the multi curl handle
$mh = curl_multi_init();
$handles = array();
for($i=0;$i<5;$i++)
{
// create a new single curl handle
$ch = curl_init();
// setting several options like url, timeout, returntransfer
// simulate multithreading by calling the wait.php script and sleeping for $rand seconds
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/IPtest/Timeout.asmx/HelloWorld");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch , CURLOPT_POSTFIELDS,"test='($i+1)'&value='ram'");
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
// add this handle to the multi handle
curl_multi_add_handle($mh,$ch);
// put the handles in an array to loop this later on
$handles[] = $ch;
}
// execute the multi handle
$running=null;
do
{
curl_multi_exec($mh,$running);
// added a usleep for 0.25 seconds to reduce load
usleep (250000);
} while ($running > 0);
// get the content of the urls (if there is any)
for($i=0;$i<count($handles);$i++)
{
// get the content of the handle
$output=curl_multi_getcontent($handles[$i]);
// remove the handle from the multi handle
curl_multi_remove_handle($mh,$handles[$i]);
//echo the output to the screen multiple times
echo $output."<br>";
}
// echo the output to the screen
// echo $output;
// close the multi curl handle to free system resources
curl_multi_close($mh);
?>
