在 foreach 循环中使用 cURL (php)

Question

我有很多 HTTPS-URLS，我必须找到一个特殊短语，所以我\xc2\xb4m 尝试在 foreach 循环中使用 cURL，但它\xc2\xb4s 不起作用。

\n\n

...\nforeach($sites as $site) {\n\n    $URL = $site;        \n\n    $ch = curl_init();\n    curl_setopt($ch, CURLOPT_URL, $url);\n\n    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);\n\n    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);\n    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);\n\n    $response = curl_exec($ch);\n    curl_close($ch);\n\n}\n\nprint substr($response, $start, $i);\n...\n

如果我只使用一个 HTTPS-URL，我会得到短语，但在 foreach 循环中，它\xc2\xb4s 不起作用。\n有人可以帮助我吗？（：

请原谅我糟糕的英语..

这可能会有所帮助:) 将结果存储在数组中

$sites = ['https://stackoverflow.com','http://example.org'];
$result = [];
foreach ($sites as $site) {

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $site);

    // User agent
    curl_setopt($ch, CURLOPT_USERAGENT, "PHP Curl");

    // Include header in result? (0 = yes, 1 = no)
    curl_setopt($ch, CURLOPT_HEADER, 0);

    // Should cURL return or print out the data? (true = return, false = print)
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    // Timeout in seconds
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);

    // execute the given URL, and return output
    $result[] = curl_exec($ch);

    curl_close($ch);


}

var_dump($result);
