是否有可用于PHP的文件描述脚本的文件扩展名？

Question

我正在寻找的东西将采取任何文件扩展名给它，并返回该扩展的描述。

例如：

$extension = 'PNG'; 
$description = ext_description($extension); 

echo $description // Outputs 'Portable Network Graphic' 

OR

$extension = 'DOC'; 
$description = ext_description($extension); 

echo $description // Outputs 'Microsoft Office Word Document' 

我搜索谷歌和一无所获。如果有人知道这样的脚本是否存在，这将是一个巨大的节省时间。

在此先感谢。

Answer 1

是的，有一个是getID3 Library and there is the PHP build in fileinfo library。

由于每个人的描述都是别的，您可以创建一个简单的查找函数来处理数组数据。您只需要将文件类型添加到阵列中即可完成：

function ext_description($extension) { 
    static extensions = array(
     'png' => 'Portable Network Graphic', 
     'doc' => 'Microsoft Office Word Document' 
    ); 
    $extension = strtolower($extension); 
    return isset($extensions[$extension]) 
     ? $extensions[$extension] 
     : sprintf('Unknown File (%s)', $extension) 
     ; 
} 

Answer 2

它不存在但您可以创建一个。

function ext_description($extension) { 
    switch ($extension) { 
    case "png": 
     return "Portable Network Graphic"; 
    case "doc": 
     return "Microsoft Office Word Document"; 
    default: 
     return "Unknow extention"; 
} 

你可以在这里找到所有现有的扩展的完整列表：）http://en.wikipedia.org/wiki/List_of_file_formats_(alphabetical

Answer 3

没有，有没有简单的方法在PHP中做到这一点。最接近的替代方法是您可以使用finfo或mime_content_type获得的MIME类型。

如果你在windows上运行，你也可以使用SHGetFileInfo函数，它正是你要找的。

这是我目前使用的上述问题，如果其他人永远需要它。

/** 
* Takes a file extension and returns a readable file type. 
* 
* @param string $ext 
* @return string 
* @example .doc returns Microsoft Word Document 
*/ 
function file_extension_2_type($ext) { 

    $files = json_decode('{".doc":"Microsoft Word Document",".docx":"Microsoft Word Open XML Document",".log":"Log File",".msg":"Outlook Mail Message",".pages":"Pages Document",".rtf":"Rich Text Format File",".txt":"Plain Text File",".wpd":"WordPerfect Document",".wps":"Microsoft Works Word Processor Document",".csv":"Comma Separated Values File",".dat":"Data File",".efx":"eFax Document",".gbr":"Gerber File",".key":"Keynote Presentation",".pps":"PowerPoint Slide Show",".ppt":"PowerPoint Presentation",".pptx":"PowerPoint Open XML Presentation",".sdf":"Standard Data File",".vcf":"vCard File",".xml":"XML File",".aif":"Audio Interchange File Format",".iff":"Interchange File Format",".m3u":"Media Playlist File",".m4a":"MPEG-4 Audio File",".mid":"MIDI File",".mp3":"MP3 Audio File",".mpa":"MPEG-2 Audio File",".wav":"WAVE Audio File",".wma":"Windows Media Audio File",".3g2":"3GPP2 Multimedia File",".3gp":"3GPP Multimedia File",".asf":"Advanced Systems Format File",".asx":"Microsoft ASF Redirector File",".avi":"Audio Video Interleave File",".flv":"Flash Video File",".mov":"Apple QuickTime Movie",".mp4":"MPEG-4 Video File",".mpg":"MPEG Video File",".swf":"Shockwave Flash Movie",".vob":"DVD Video Object File",".wmv":"Windows Media Video File",".3dm":"Rhino 3D Model",".max":"3ds Max Scene File",".bmp":"Bitmap Image File",".gif":"Graphical Interchange Format File",".jpg":"JPEG Image File",".png":"Portable Network Graphic",".psd":"Adobe Photoshop Document",".pspimage":"PaintShop Pro Image",".thm":"Thumbnail Image File",".tif":"Tagged Image File",".yuv":"YUV Encoded Image File",".ai":"Adobe Illustrator File",".drw":"Drawing File",".eps":"Encapsulated PostScript File",".ps":"PostScript File",".svg":"Scalable Vector Graphics File",".indd":"Adobe InDesign Document",".pct":"Picture File",".pdf":"Portable Document Format File",".qxd":"QuarkXPress Document",".qxp":"QuarkXPress Project File",".rels":"Open Office XML Relationships File",".xlr":"Works Spreadsheet",".xls":"Excel Spreadsheet",".xlsx":"Microsoft Excel Open XML Spreadsheet",".accdb":"Access 2007 Database File",".db":"Database File",".dbf":"Database File",".mdb":"Microsoft Access Database",".pdb":"Program Database",".sql":"Structured Query Language Data",".app":"Mac OS X Application",".bat":"DOS Batch File",".cgi":"Common Gateway Interface Script",".com":"DOS Command File",".exe":"Windows Executable File",".gadget":"Windows Gadget",".jar":"Java Archive File",".pif":"Program Information File",".vb":"VBScript File",".wsf":"Windows Script File",".gam":"Saved Game File",".nes":"Nintendo (NES) ROM File",".rom":"N64 Game ROM File",".sav":"Saved Game",".dwg":"AutoCAD Drawing Database File",".dxf":"Drawing Exchange Format File",".gpx":"GPS Exchange File",".kml":"Keyhole Markup Language File",".asp":"Active Server Page",".cer":"Internet Security Certificate",".csr":"Certificate Signing Request File",".css":"Cascading Style Sheet",".htm":"Hypertext Markup Language File",".html":"Hypertext Markup Language File",".js":"JavaScript File",".jsp":"Java Server Page",".php":"Hypertext Preprocessor File",".rss":"Rich Site Summary",".xhtml":"Extensible Hypertext Markup Language File",".8bi":"Photoshop Plug-in",".plugin":"Mac OS X Plug-in",".xll":"Excel Add-In File",".fnt":"Windows Font File",".fon":"Generic Font File",".otf":"OpenType Font",".ttf":"TrueType Font",".cab":"Windows Cabinet File",".cpl":"Windows Control Panel Item",".cur":"Windows Cursor",".dll":"Dynamic Link Library",".dmp":"Windows Memory Dump",".drv":"Device Driver",".lnk":"File Shortcut",".sys":"Windows System File",".cfg":"Configuration File",".ini":"Windows Initialization File",".keychain":"Mac OS X Keychain File",".prf":"Outlook Profile File",".bin":"Macbinary Encoded File",".hqx":"BinHex 4.0 Encoded File",".mim":"Multi-Purpose Internet Mail Message File",".uue":"Uuencoded File",".7z":"7-Zip Compressed File",".deb":"Debian Software Package",".gz":"Gnu Zipped Archive",".pkg":"Mac OS X Installer Package",".rar":"WinRAR Compressed Archive",".rpm":"Red Hat Package Manager File",".sit":"Stuffit Archive",".sitx":"Stuffit X Archive",".tar.gz":"Tarball File",".zip":"Zipped File",".zipx":"Extended Zip File",".dmg":"Mac OS X Disk Image",".iso":"Disc Image File",".toast":"Toast Disc Image",".vcd":"Virtual CD",".c":"C\/C++ Source Code File",".class":"Java Class File",".cpp":"C++ Source Code File",".cs":"Visual C# Source Code File",".dtd":"Document Type Definition File",".fla":"Adobe Flash Animation",".java":"Java Source Code File",".m":"Objective-C Implementation File",".pl":"Perl Script",".py":"Python Script",".bak":"Backup File",".gho":"Norton Ghost Backup File",".ori":"Original File",".tmp":"Temporary File",".dbx":"Outlook Express E-mail Folder",".msi":"Windows Installer Package",".part":"Partially Downloaded File",".torrent":"BitTorrent File"}', true); 


    if (isset($files['.' . strtolower($ext)])) 
     return $files['.' . strtolower($ext)] . ' (' . strtoupper($ext) . ')'; 


    return strtoupper($ext); 
}
