在php使用curl時(shí)必須先在php.ini中開(kāi)啟extension=php_curl.dll前面的;去了才行,curl是php中一款內(nèi)置的瀏覽器,它可以模仿用戶瀏覽信息進(jìn)行網(wǎng)站瀏覽,等下面來(lái)看一實(shí)例,代碼如下:
- function postpage($url)
- {
- $response = "";
- $rd=rand(1,4);
- $proxy='http://221.214.27.253:808';
- if($rd==2) $proxy='http://222.77.14.56:8088';
- if($rd==3) $proxy='http://202.98.123.126:8080';
- if($rd==4) $proxy='http://60.14.97.38:8080';
- if($url != "") {
- $ch = curl_init($url);
- curl_setopt($ch, curlopt_header, 0);
- curl_setopt($ch, curlopt_returntransfer, true);
- curl_setopt($ch, curlopt_proxy, $proxy);
- $response = curl_exec($ch);
- if(curl_errno($ch)) $response = "";
- curl_close($ch);
- }
- return $response;
- }
