因此从我的理解来看,这应该相当简单,因为我应该只需要更改原始文件集内容代码,并且脚本的其余部分仍然可以工作?我已经注释掉了旧文件获取内容并添加了下面的卷曲。CURL替代内置的“file_get_contents()”函数
从文件中更改获取内容卷曲下面的代码后不会输出
//$data = @file_get_contents("http://www.city-data.com/city/".$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>~

$detailsBlock3 = <<<HTML
~<div style='clear:both;'></div><br/><b>(.*?) on our <a href='http://www.city-data.com/top2/toplists2.html'>top lists</a>: </b><ul style='margin:10px;'>(.*?)</ul></td>~
HTML;
preg_match($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];
}
else
{
$facts = "More Information to Come...";
}
为什么要使用cURL而不是file_get_contents? – Halcyon 2011-06-10 19:57:02
@Frits van Campen,因为建议使用Curl。许多网络服务器主机关闭使用file_get_contents()的选项; – joakimdahlstrom 2011-06-10 20:00:30
所以你改变代码W/O实际上需要改变它?玩的开心! – hakre 2011-06-10 20:01:42
