因此從我的理解來看,這應該相當簡單,因爲我應該只需要更改原始文件集內容代碼,並且腳本的其餘部分仍然可以工作?我已經註釋掉了舊文件獲取內容並添加了下面的捲曲。CURL替代內置的「file_get_contents()」函數
從文件中更改獲取內容捲曲下面的代碼後不會輸出
//$data = @file_get_contents("http://www.city-data.com/city/".$cityActualURL."-".$stateActualURL.".html");
//$data = file_get_contents("http://www.city-data.com/city/Geneva-Illinois.html");
//Initialize the Curl session
$ch = curl_init();
$url= "http://www.city-data.com/city/".$cityActualURL."-".$stateActualURL.".html";
//echo "$url<br>";
$ch = curl_init();
$timeout = 5;
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
$data = curl_exec($ch);
curl_close($ch);
//echo $data;
$details = str_replace("\n", "", $data);
$details = str_replace("\r", "", $details);
$detailsBlock = <<<HTML
~<div style='clear:both;'></div><br/><b>(.*?) on our <a href='http://www.city-data.com/top2/toplists2.html'>top lists</a>: </b><ul style='margin:10px;'>(.*?)<div style='bp_bindex'>~
HTML;
$detailsBlock2 = <<<HTML
~<br/><br/><b>(.*?) on our <a href='http://www.city-data.com/top2/toplists2.html'>top lists</a>: </b><ul style='margin:10px;'>(.*?)</ul></td>~

$detailsBlock3 = <<<HTML

HTML;
preg_match($detailsBlock, $details, $matches);
preg_match($detailsBlock2, $details, $matches2);
preg_match($detailsBlock3, $details, $matches3);
if (isset($matches[2]))
{
$facts = "<ul style='margin:10px;'>".$matches[2];
}
elseif (isset($matches2[2]))
{
$facts = "<ul style='margin:10px;'>".$matches2[2];
}
elseif (isset($matches3[2]))

$facts = "<ul style='margin:10px;'>".$matches3[2];

爲什麼要使用cURL而不是file_get_contents? – Halcyon 2011-06-10 19:57:02
@Frits van Campen,因爲建議使用Curl。許多網絡服務器主機關閉使用file_get_contents()的選項; – joakimdahlstrom 2011-06-10 20:00:30
所以你改變代碼W/O實際上需要改變它?玩的開心! – hakre 2011-06-10 20:01:42
