我想知道是否可以使用cURL或其他方式打开多个URL.
直到现在我都尝试过.
$urls = array(
"http://google.com",
"http://youtube.com",
);
foreach($urls as $url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT,0);
curl_setopt($ch, CURLOPT_TIMEOUT_MS, 200);
curl_exec($ch);
curl_close($ch);
}
200毫秒可让站点完全打开.
也许您知道其他选择.
是否可以同时在PHP中打开多个URL?不是客户端,而是服务器端.
解决方法:
您的解决方案是同时执行cURL HTTP请求.
为了更快地实现,您可以使用以下功能(感谢phpied):
function multiRequest($data, $options = array()) {
// array of curl handles
$curly = array();
// data to be returned
$result = array();
// multi handle
$mh = curl_multi_init();
// loop through $data and create curl handles
// then add them to the multi-handle
foreach ($data as $id => $d) {
$curly[$id] = curl_init();
$url = (is_array($d) && !empty($d['url'])) ? $d['url'] : $d;
curl_setopt($curly[$id], CURLOPT_URL, $url);
curl_setopt($curly[$id], CURLOPT_HEADER, 0);
curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, 1);
// post?
if (is_array($d)) {
if (!empty($d['post'])) {
curl_setopt($curly[$id], CURLOPT_POST, 1);
curl_setopt($curly[$id], CURLOPT_POSTFIELDS, $d['post']);
}
}
// extra options?
if (!empty($options)) {
curl_setopt_array($curly[$id], $options);
}
curl_multi_add_handle($mh, $curly[$id]);
}
// execute the handles
$running = null;
do {
curl_multi_exec($mh, $running);
} while($running > 0);
// get content and remove handles
foreach($curly as $id => $c) {
$result[$id] = curl_multi_getcontent($c);
curl_multi_remove_handle($mh, $c);
}
// all done
curl_multi_close($mh);
return $result;
}
并像这样使用它:
$data = array(
'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Pearl+Jam&output=json',
'http://search.yahooapis.com/ImageSearchService/V1/imageSearch?appid=YahooDemo&query=Pearl+Jam&output=json',
'http://search.yahooapis.com/AudioSearchService/V1/artistSearch?appid=YahooDemo&artist=Pearl+Jam&output=json'
);
$r = multiRequest($data);
echo '<pre>';
print_r($r);
希望能帮助到你.
