Laravel 5 - get MIME type from file extension
提问by Limon Monte
In Laravel 5 how can I get MIME type from extension? Even better if there's a way to convert array of extensions to array of mimes.
在 Laravel 5 中，如何从扩展中获取 MIME 类型？如果有一种方法可以将扩展数组转换为 mime 数组，那就更好了。
E.g. how to convert array('doc', 'xls')to array('application/msword', 'application/vnd.ms-excel')?
例如如何转换array('doc', 'xls')为array('application/msword', 'application/vnd.ms-excel')？

When "guzzlehttp/guzzle": "~5.3|~6.0" is in your composer.json, you can use this:
当 "guzzlehttp/guzzle": "~5.3|~6.0" 在你的 composer.json 中时，你可以使用这个：
$mimetype = \GuzzleHttp\Psr7\mimetype_from_filename('foo.doc');
$mimetype = \GuzzleHttp\Psr7\mimetype_from_extension('doc');

Guzzleis included in Laravel 5 by default, there's the list of mime typesin this library and fromExtension()method which do exaclty what was asked.
默认情况下，Guzzle包含在 Laravel 5中，这个库和方法中的 mime 类型列表可以准确地fromExtension()完成所要求的内容。
So, to get MIME type of single extension:
因此，要获得 MIME 类型的单个扩展名：
$mimetypes = new \GuzzleHttp\Mimetypes;
$mime = $mimetypes->fromExtension($extension);
To get array of MIME types from array of extensions:
从扩展数组中获取 MIME 类型数组：
$mimetypes = new \GuzzleHttp\Mimetypes;
$mimes = [];
foreach ($extensions as $extension) {
$mimes[] = $mimetypes->fromExtension($extension);
}

First, you need to download this public domain file: http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
首先，您需要下载这个公共域文件：http: //svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
Then use the following function to read the file and get the corresponding MIMEtype for an extension:
然后使用以下函数读取文件并获取MIME扩展名的相应类型：
function getMIME($extension) {
$file = "mime.types";
$in = fopen($file, "r");
while (($line = fgets($in)) !== false) {
if (preg_match("/([a-z]+\/[a-z]+)\s+([a-z\s]*)\b($extension)\b/", $line, $match)) {
return $match[1];
}
}
fclose($in);
return "error";
}
echo getMIME("doc");
Output:
输出：
application/msword
应用程序/msword
To convert the array:
要转换数组：
$myArray = array('doc', 'xls');
foreach($myArray as $key => $value){
$myArray[$key] = getMIME($value);
}
