我今天从某人那里得到一个提示,我的curl_multi()
代码实际上是串行工作的,而我希望并行化 cURL 请求。
我的代码仍然是串行的吗?如果是这样,我该如何并行化?
以下是相关代码:
/**
* Returns the cURL responses given multiple target URLs
* @param array $targetUrls Array of target URLs for cURL
*
* @return array cURL Responses
*/
private function getCurlMultiResponses($targetUrls)
{
// Cache the count
$count = count($targetUrls);
// Create the multiple cURL handles
for($i = 0; $i < $count; $i++) {
$ch[$i] = curl_init($targetUrls[$i]);
curl_setopt($ch[$i], CURLOPT_POST, FALSE);
curl_setopt($ch[$i], CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch[$i], CURLOPT_RETURNTRANSFER, TRUE);
}
// Initialize the multiple cURL handle
$mh = curl_multi_init();
// Add the handles to the curl_multi handle
for($i = 0; $i < $count; $i++) {
curl_multi_add_handle($mh, $ch[$i]);
}
$running = null;
// Execute the handles
do {
curl_multi_exec($mh, $running);
} while ($running > 0);
$responses = array();
// Remove the handles and return the response
for($i = 0; $i < $count; $i++) {
curl_multi_remove_handle($mh, $ch[$i]);
$responses[$i] = curl_multi_getcontent($ch[$i]);
}
// Close the multiple cURL handle
curl_multi_close($mh);
return $responses;
}
