$ch = curl_init();
// 设置 URL 和其它相应的选项
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/');
curl_setopt($ch, CURLOPT_HEADER, 0);
// 复制句柄
$ch2 = curl_copy_handle($ch);
// 抓取 URL（http://www.example.com/）并把它传递给浏览器
curl_exec($ch2);
// 关闭 cURL 资源，并且释放系统资源
curl_close($ch2);
curl_close($ch);
?>There is some internal curl error (CURLE_FAILED_INIT) when you are trying to use just copied curl handle in curl_multi_add_handle(). I have checked the same problematic PHP code but with little difference: instead of creating curl’s copy I have used the original one (template). As I expect code works without any error. I think curl_multi_* along with curl_copy_handle() is still raw and needs some improvements.
With best wishes
Vitali SimsiveYou can use it for some kind of templates:
<?php
$ch = array();
$ch[0] = curl_init();
curl_setopt($ch[0], CURLOPT_URL, 'http://beengo.net/');
curl_setopt($ch[0], CURLOPT_HEADER, 0);
curl_setopt($ch[0], CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch[0], CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch[0], CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
$ch[1] = curl_copy_handle($ch[0]);
curl_setopt($ch[1], CURLOPT_URL, 'http://beengo.net/cells/list');
$ch[2] = curl_copy_handle($ch[0]);
curl_setopt($ch[2], CURLOPT_URL, 'http://beengo.net/cells/list?q=travel');
/* And so on, when you need to get number of pages with same parameters... */
?>Hmm I don't have a problem with this, using PHP 5.2.5 libcurl 7.16.3 maybe it's been fixed ...
I am m having trouble getting curl_copy_handle to copy all the curlopts across though...
protected function curlMultiPrime(array $reqArr){
// Store the request array so we can reinitialise the multi handle
$this->reqArr = $reqArr;
// Close existing curl uni handles
$this->closeMultiCurlUniHandles();
foreach($reqArr as $curlConf){
if(!($curlConf instanceof curlConfRequest ))
throw new curlConfException('All objects passed to configure requests must be instances of curlConfRequest.',curlConfException::CURL_INVALID_CONF_OBJ);
if(!$cch = curl_copy_handle($this->curlHandle)){
throw new curlException('Failed to clone template curl handle.',$this->curlHandle);
}else{
curl_setopt_array($cch,$curlConf->getCurlOpts());
}
if(curl_multi_add_handle($this->curlMultiHandle,$cch) === 0){
$this->curlUniHandleRef[] = $cch;
}else{
throw new curlException('Failed to add curl handle to multi stack.',$cch);
}
