php – 如何使用cURL刮取iframe内容

目标：我想使用cURL在iframe中删除“Paris”一词.

假设您有一个包含iframe的简单页面：

<html>
<head>
<title>Curl into this page</title>
</head>
<body>

<iframe src="france.html" title="test" name="test">

</body>
</html>

iframe页面：

<html>
<head>
<title>France</title>
</head>
<body>

<p>The Capital of France is: Paris</p>

</body>
</html>

我的cURL脚本：

<?PHP>

// 1. initialize

$ch = curl_init();

// 2. The URL containing the iframe

$url = "http://localhost/test/index.html";

// 3. set the options, including the url

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 2);
curl_setopt($ch, CURLOPT_MAXREDirs, 10);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

// 4. execute and fetch the resulting HTML output by putting into $output

$output = curl_exec($ch);

// 5. free up the curl handle

curl_close($ch);

// 6. Scrape for a single string/word ("Paris") 

preg_match("'The Capital of France is:(.*?). </p>'si", $output, $match);
if($match) 

// 7. display the scraped string 

echo "The Capital of France is: ".$match[1];

?>

结果=没事！

有人能帮我找到法国的首都吗？！
