php如何用代理访问网站 求代码

CURL 就可以啊！你的先自己开个http代理 。或者百度找一些http代理

然后在curl里面设置http代理就可以了。

function curl_string ($url,$user_agent,$proxy){       

       $ch = curl_init()

       curl_setopt ($ch, CURLOPT_PROXY, $proxy)

       curl_setopt ($ch, CURLOPT_URL, $url)

       curl_setopt ($ch, CURLOPT_USERAGENT, $user_agent)

       curl_setopt ($ch, CURLOPT_COOKIEJAR, "c:\cookie.txt")//可删除

       curl_setopt ($ch, CURLOPT_HEADER, 1)

       curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1)

       curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1)

       curl_setopt ($ch, CURLOPT_TIMEOUT, 120)       

       $result = curl_exec ($ch)

       curl_close($ch)       

       return $result

}

$content = "http://www.google.com"$user_agent = "Mozilla/4.0"$proxy = "http://192.11.222.124:8000"

function curl_string ($url,$timeout = 3,$proxy=1){

$ua = array('Mozilla','Opera','Microsoft Internet Explorer','ia_archiver')

$op = array('Windows','Windows XP','Linux','Windows NT','Windows 2000','OSX')

$agent = $ua[rand(0,3)].'/'.rand(1,8).'.'.rand(0,9).' ('.$op[rand(0,5)].' '.rand(1,7).'.'.rand(0,9).'en-US)'

Tor 地址与端口

$tor = 'http://www.aimilife.com' //这里是你的代理服务器

连接超时设置

$timeout = 3

$ack = curl_init()

if($proxy)

{

curl_setopt($ack, CURLOPT_PROXY, $tor)

}

curl_setopt($ack, CURLOPT_URL, $url)

curl_setopt($ack, CURLOPT_HEADER, 0)

curl_setopt($ack, CURLOPT_USERAGENT, $agent)

curl_setopt($ack, CURLOPT_RETURNTRANSFER, 1)

curl_setopt($ack, CURLOPT_FOLLOWLOCATION, 1)

curl_setopt($ack, CURLOPT_TIMEOUT, $timeout)

$result = curl_exec($ack)

curl_close($ack)

return $result

}
