我注意到get_mime()现在已经折旧了,那么创建以下函数的替代方法是什么?此功能通过我使用的cms使用,因此需要一个可靠的替代方案。
// Mime Type Checker
function get_mime ($filename,$mode=0) {
// mode 0 = full check
// mode 1 = extension check only
$mime_types = array(
'txt' => 'text/plain',
'htm' => 'text/html',
'html' => 'text/html',
'php' => 'text/html',
'css' => 'text/css',
'js' => 'application/javascript',
'json' => 'application/json',
'xml' => 'application/xml',
'swf' => 'application/x-shockwave-flash',
'flv' => 'video/x-flv',
// images
'png' => 'image/png',
'jpe' => 'image/jpeg',
'jpeg' => 'image/jpeg',
'jpg' => 'image/jpeg',
'gif' => 'image/gif',
'bmp' => 'image/bmp',
'ico' => 'image/vnd.microsoft.icon',
'tiff' => 'image/tiff',
'tif' => 'image/tiff',
'svg' => 'image/svg+xml',
'svgz' => 'image/svg+xml',
// archives
'zip' => 'application/zip',
'rar' => 'application/x-rar-compressed',
'exe' => 'application/x-msdownload',
'msi' => 'application/x-msdownload',
'cab' => 'application/vnd.ms-cab-compressed',
// audio/video
'mp3' => 'audio/mpeg',
'qt' => 'video/quicktime',
'mov' => 'video/quicktime',
// adobe
'pdf' => 'application/pdf',
'psd' => 'image/vnd.adobe.photoshop',
'ai' => 'application/postscript',
'eps' => 'application/postscript',
'ps' => 'application/postscript',
// ms office
'doc' => 'application/msword',
'rtf' => 'application/rtf',
'xls' => 'application/vnd.ms-excel',
'ppt' => 'application/vnd.ms-powerpoint',
'docx' => 'application/msword',
'xlsx' => 'application/vnd.ms-excel',
'pptx' => 'application/vnd.ms-powerpoint',
// open office
'odt' => 'application/vnd.oasis.opendocument.text',
'ods' => 'application/vnd.oasis.opendocument.spreadsheet',
);
$ext = strtolower(array_pop(explode('.',$filename)));
if (function_exists('mime_content_type') && $mode==0) {
$mimetype = mime_content_type($filename);
return $mimetype;
}
if (function_exists('finfo_open') && $mode==0) {
$finfo = finfo_open(FILEINFO_MIME);
$mimetype = finfo_file($finfo, $filename);
finfo_close($finfo);
return $mimetype;
} elseif (array_key_exists($ext, $mime_types)) {
return $mime_types[$ext];
} else {
return 'application/octet-stream';
}
}

finfo_file替代mime_content_type
。
由于finfo_file
仅在PHP 5.3.0+中可用,因此您所做的是正确的。如果finfo_file
可用,则使用它,否则回退到mime_content_type,如果我们无法使用finfo_file
,则应该可以使用。
您应该像这样更新条件检查:
if(function_exists('mime_content_type')&&$mode==0){
$mimetype = mime_content_type($filename);
return $mimetype;
}elseif(function_exists('finfo_open')&&$mode==0){
$finfo = finfo_open(FILEINFO_MIME);
$mimetype = finfo_file($finfo, $filename);
finfo_close($finfo);
return $mimetype;
}elseif(array_key_exists($ext, $mime_types)){
return $mime_types[$ext];
}else {
return 'application/octet-stream';
}

我刚刚使用过这样的东西,只要你有PHP版本>它似乎工作正常。 5.3.0:
$fn = "/dir/filename.whatever"
$mime = finfo_open(FILEINFO_MIME,$mimepath);
$filetype = finfo_file($mime,$fn);
finfo_close($mime);
请注意;我记得$mimepath
是一个未设置的变量。这将导致finfo_open()
使用其第二个参数的默认值。

$mime = `file --mime-type $path`;
$mime = trim(array_pop(explode(':', $mime)));
这适合我。
