我使用了mime_content_type()
和文件信息,但我从未成功过。我想现在使用cURL与PHP并获取托管在另一个域上的文件的标题然后解压缩&确定类型是否为MP3。 (我认为mime类型的MP3是audio/mpeg
)
简单地说,我知道但我不知道如何应用它:)

您可以通过curl使用HEAD请求。像:
$ch = curl_init();
$url = 'http://sstatic.net/so/img/logo.png';
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_NOBODY, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$results = explode("\n", trim(curl_exec($ch)));
foreach($results as $line) {
if (strtok($line, ':') == 'Content-Type') {
$parts = explode(":", $line);
echo trim($parts[1]);
}
}
返回: image / png

如果您对使用Zend_Http_Client组件的更优雅的Zend Framework版本here is a class感到满意。
像这样使用它:
$sniffer = new Smartycode_Http_Mime();
$contentType = $sniffer->getMime($url);
