我做了一個腳本,遍歷第三方網站尋找數據的幾頁,我需要在crontable上每天運行一次。我目前編寫的方式是在瀏覽器上測試它的功能,如果找不到所需的數據,腳本會使用javascript重新加載以轉到下一頁。所以這在cron中不起作用。與簡單的通過功能循環的問題是,我不能運行這個功能多次:HTTP_GET()由PHP cron重新加載困境
function http_get($target, $ref)
{
return http($target, $ref, $method="GET", $data_array="", EXCL_HEAD);
}
function http($target, $ref, $method, $data_array, $incl_head)
{
# Initialize PHP/CURL handle
$ch = curl_init();
# Prcess data, if presented
if(is_array($data_array))
{
# Convert data array into a query string (ie animal=dog&sport=baseball)
foreach ($data_array as $key => $value)
{
if(strlen(trim($value))>0)
$temp_string[] = $key . "=" . urlencode($value);
else
$temp_string[] = $key;
}
$query_string = join('&', $temp_string);
}
# HEAD method configuration
if($method == HEAD)
{
curl_setopt($ch, CURLOPT_HEADER, TRUE); // No http head
curl_setopt($ch, CURLOPT_NOBODY, TRUE); // Return body
}
else
{
# GET method configuration
if($method == GET)
{
if(isset($query_string))
$target = $target . "?" . $query_string;
curl_setopt ($ch, CURLOPT_HTTPGET, TRUE);
curl_setopt ($ch, CURLOPT_POST, FALSE);
}
# POST method configuration
if($method == POST)
{
if(isset($query_string))
curl_setopt ($ch, CURLOPT_POSTFIELDS, $query_string);
curl_setopt ($ch, CURLOPT_POST, TRUE);
curl_setopt ($ch, CURLOPT_HTTPGET, FALSE);
}
curl_setopt($ch, CURLOPT_HEADER, $incl_head); // Include head as needed
curl_setopt($ch, CURLOPT_NOBODY, FALSE); // Return body
}
curl_setopt($ch, CURLOPT_COOKIEJAR, COOKIE_FILE); // Cookie management.
curl_setopt($ch, CURLOPT_COOKIEFILE, COOKIE_FILE);
curl_setopt($ch, CURLOPT_TIMEOUT, CURL_TIMEOUT); // Timeout
curl_setopt($ch, CURLOPT_USERAGENT, WEBBOT_NAME); // Webbot name
curl_setopt($ch, CURLOPT_URL, $target); // Target site
curl_setopt($ch, CURLOPT_REFERER, $ref); // Referer value
curl_setopt($ch, CURLOPT_VERBOSE, FALSE); // Minimize logs
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // No certificate
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); // Follow redirects
curl_setopt($ch, CURLOPT_MAXREDIRS, 4); // Limit redirections to four
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); // Return in string
$return_array['FILE'] = curl_exec($ch);
# Create return array
$return_array['STATUS'] = curl_getinfo($ch);
$return_array['ERROR'] = curl_error($ch);
# Close PHP/CURL handle
curl_close($ch);
# Return results
return $return_array;
}
任何方式,我可以解決這個定義?謝謝
嗯,也許我的問題是我想重新實例化一個函數從內部本身? like function x(){if($ y = 0){x();}} ?? – 2012-02-06 19:26:30
因爲我的問題很糟糕,你幫助我,我得到它的工作!謝謝 – 2012-02-06 20:39:18
