Php exact method to get file MIME type, _php tutorial

PHP exactly gets the file MIME type method,

The example in this article describes how PHP gets the file MIME type exactly. Share to everyone for your reference. The implementation method is as follows:

<?php$mime = Array (//applications ' ai ' = ' application/postscript ', ' eps ' = ' Application/postscrip T ', ' exe ' = ' application/octet-stream ', ' doc ' = ' application/vnd.ms-word ', ' xls ' = ' application/vn ' D.ms-excel ', ' ppt ' = ' application/vnd.ms-powerpoint ', ' pps ' = ' application/vnd.ms-powerpoint ', ' pdf ' = > ' application/pdf ', ' xml ' = ' application/xml ', ' odt ' = ' application/vnd.oasis.opendocument.text ', ' swf ' = ' application/x-shockwave-flash ',//Archives ' gz ' = ' application/x-gzip ', ' tgz ' = ' applicat ' Ion/x-gzip ', ' bz ' = ' application/x-bzip2 ', ' bz2 ' = ' application/x-bzip2 ', ' tbz ' and ' application/x-b ' Zip2 ', ' zip ' = ' application/zip ', ' rar ' = ' application/x-rar ', ' tar ' = ' application/x-tar ', ' 7z ' = = ' application/x-7z-compressed ',//texts ' txt ' = ' text/plain ', ' php ' = ' text/x-php ', ' HTML ' = ' text/html ', ' HTM ' = ' text/html ', ' js ' = ' text/javascript ', ' css ' = ' text/css ', ' rtf ' = ' text/rtf ', ' rtfd    ' = ' text/rtfd ', ' py ' = ' Text/x-python ', ' java ' = ' text/x-java-source ', ' rb ' = ' Text/x-ruby ', ' sh ' = ' text/x-shellscript ', ' pl ' = ' text/x-perl ', ' sql ' = ' text/x-sql ',//images ' BMP ' =&G T  ' Image/x-ms-bmp ', ' jpg ' = ' image/jpeg ', ' jpeg ' = ' image/jpeg ', ' gif ' = ' image/gif ', ' png ' =  ' Image/png ', ' tif ' = ' image/tiff ', ' tiff ' = ' image/tiff ', ' tga ' = ' image/x-targa ', ' psd ' = ' Image/vnd.adobe.photoshop ',//audio ' mp3 ' = ' audio/mpeg ', ' mid ' = ' Audio/midi ', ' ogg ' = ' Audi  O/ogg ', ' mp4a ' = ' audio/mp4 ', ' wav ' = ' audio/wav ', ' wma ' = ' audio/x-ms-wma ',//video ' avi '  = ' Video/x-msvideo ', ' dv ' = ' video/x-dv ', ' mp4 ' = ' video/mp4 ', ' mpeg ' = ' video/mpeg ', ' mpg ' = ' Video/mpeg ',   ' mov ' = ' video/quicktime ', ' wm ' = ' video/x-ms-wmv ', ' flv ' = ' video/x-flv ', ' mkv ' = ' video/  X-matroska '), function _getmimedetect () {if (class_exists (' Finfo ')) {return ' finfo ';  } else if (function_exists (' Mime_content_type ')) {return ' Mime_content_type ';    } else if (function_exists (' exec ')) {$result = exec (' File-ib '. Escapeshellarg (__file__));    if (0 = = Strpos ($result, ' text/x-php ') OR 0 = = = Strpos ($result, ' text/x-c++ ')) {return ' Linux ';    } $result = exec (' File-ib '. Escapeshellarg (__file__));    if (0 = = Strpos ($result, ' text/x-php ') OR 0 = = = Strpos ($result, ' text/x-c++ ')) {return ' BSD '; }} return ' internal ';}  function _getmimetype ($path) {global $mime;  $fmime = _getmimedetect ();      Switch ($fmime) {case ' finfo ': $finfo = Finfo_open (fileinfo_mime);      if ($finfo) $type = @finfo_file ($finfo, $path);    Break      Case ' Mime_content_type ': $type = Mime_content_type ($path); Break    Case ' Linux ': $type = exec (' File-ib '. Escapeshellarg ($path));    Break      Case ' BSD ': $type = exec (' File-ib '. Escapeshellarg ($path));    Break      Default: $pinfo = PathInfo ($path); $ext = Isset ($pinfo [' extension '])?      Strtolower ($pinfo [' extension ']): '; $type = Isset ($mime [$ext])?      $mime [$ext]: ' Unkown ';  Break  } $type = explode ('; ', $type); This paragraph needs to be added, because if you use the Mime_content_type function to get a nonexistent $path, you return ' Application/octet-stream ' if ($fmime! = ' internal ' and $type [0]     = = ' Application/octet-stream ') {$pinfo = PathInfo ($path); $ext = Isset ($pinfo [' extension '])?    Strtolower ($pinfo [' extension ']): ';    if (!empty ($ext) and!empty ($mime [$ext])) {$type [0] = $mime [$ext]; }} return $type [0];} $path = ' 1.txt '; In fact, the current path does not exist 1.txtvar_dump (_getmimetype ($path));/*end of php*/

I hope this article is helpful to everyone's PHP programming.
