我需要檢查關鍵字位置谷歌列表的域名。谷歌關鍵詞位置檢查工作不正常
實施例：
Domain1.com
- 關鍵字1 - GOOGLE_POSITION
- 關鍵字2 - GOOGLE_POSITION
- KEYWORD3 - GOOGLE_POSITION
Domain2.com
- 關鍵字1 - GOOGLE_POSITION
- 關鍵字2 - GOOGLE_POSITION
- KEYWORD3 - GOOGLE_POSITION
這是我的代碼：
<?php
///////// GOOGLE KEYWORD RANK - start
// this function get invokes when user click particular link once after create account (for resume creation)
function getmethod_setCurloption($ch,$ckfile,$google_url)
{
//$useragent="Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1";
//curl_setopt($ch, CURLOPT_USERAGENT, $useragent);
curl_setopt($ch, CURLOPT_COOKIEFILE, $ckfile); //The name of the file containing the cookie data. The cookie file can be in Netscape format, or just plain HTTP-style headers dumped into a file.
curl_setopt($ch, CURLOPT_URL,$google_url); // The URL to fetch. This can also be set when initializing a session with curl_init().
curl_setopt ($ch, CURLOPT_COOKIEJAR, $ckfile); // The name of a file to save all internal cookies to when the connection closes.
curl_setopt($ch, CURLOPT_HEADER,0); // TRUE to include the header in the output.
curl_setopt($ch,CURLOPT_AUTOREFERER,1); // TRUE to automatically set the Referer: field in requests where it follows a Location: redirect.
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // TRUE to return the transfer as a string of the return value of curl_exec() instead of outputting it out directly.
curl_setopt($ch, CURLOPT_POST,0); //TRUE to do a regular HTTP POST. This POST is the normal application/x-www-form-urlencoded kind, most commonly used by HTML forms.

我打電話給我的使用功能：$位置=爲getPosition （DOMAIN_NAME，KEYWORD）; 它正在工作，但有時它幾乎立即返回我0，我有一些網站，有10個關鍵字我的腳本返回正確的位置只爲前4-5然後在所有關鍵字上0。
我該如何解決它。或者我可以找到另一個腳本？
