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？！
