他们是否可以将curl请求的输出保存在php变量中？
因为如果我只保存$result，我会得到一个1或零的
<?php
$url='http://icanhazip.com';
$proxy=file ('proxy.txt');
$useragent='Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)';
for($x=0;$x<count($proxy);$x++)
{
$ch = curl_init();
//you might need to set some cookie details up (depending on the site)
curl_setopt($ch, CURLOPT_TIMEOUT, 1);
curl_setopt($ch, CURLOPT_URL,$url); //set the url we want to use
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 0);
curl_setopt($ch, CURLOPT_PROXY, $proxy[$x]);
curl_setopt($ch, CURLOPT_USERAGENT, $useragent); //set our user agent
$result= curl_exec ($ch); //execute and get the results
print $result; //display the reuslt
$datenbank = "proxy_work.txt";
$datei = fopen($datenbank,"a");
fwrite($datei, $result);
fwrite ($datei,"'r'n");
curl_close ($ch);
}
?>
您需要将CURLOPT_RETURNTRANSFER选项设置为true。
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
您需要添加卷曲选项CURLOPT_RETURNTTRANSFER:的设置
curl_setopt（$ch，CURLOPT_RETURNTTRANSFER，1）；
这样可以避免输出并使程序继续运行。
