使用 cURL 和 php 获取 mime 类型的外部文件

问题描述：

我使用了 mime_content_type() 和文件信息，但我从未成功.我现在想在 PHP 中使用 cURL 并获取托管在另一个域上的文件的标题，然后提取 &确定类型是否为 MP3.(我认为 MP3 的 mime 类型是 audio/mpeg )

I've used mime_content_type() and File info but i never successed. i want to use now cURL with PHP and get the headers of the file which is hosted on another domain then extract & determine if the type is MP3 or not. ( i think the mime type of MP3 is audio/mpeg )

简单地说，我知道，但我不知道如何应用它:)

Briefly, i know that but i don't know how to apply it :)

谢谢

PHP curl_getinfo()

<?php
  # the request
  $ch = curl_init('http://www.google.com');
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_exec($ch);

  # get the content type
  echo curl_getinfo($ch, CURLINFO_CONTENT_TYPE);

  # output
  text/html; charset=ISO-8859-1
?>
