PHP MIME Type Sniffer
Detecting MIME Content-type in PHP is easy with
or Fileinfo. But Fileinfo as
an extension is sometimes not available on the server. The function
mime_content_type wants a path to the filesystem as argument and doesn't
process if we only have a string value. This package makes it easy to detect
the mime types of the content of a given file or string, without any extension
Install the package easily via composer:
composer require intervention/mimesniffer
Here are some code samples, to show how the library is handled.
use Intervention\MimeSniffer\MimeSniffer; use Intervention\MimeSniffer\Types\ImageJpeg; // detect given string $sniffer = MimeSniffer::createFromString($content); // or detect given file $sniffer = MimeSniffer::createFromFilename('image.jpg'); // returns object of detected type $type = $sniffer->getType(); $bool = $type->isBinary(); // check if we have binary data $bool = $type->isImage(); // check if we are dealing with an image $bool = $type->isVideo(); // check video data was detected $bool = $type->isAudio(); // check if we have detected audio data $bool = $type->isArchive(); // check if an archive was detected $type = (string) $type; // cast type to string (e.g. "image/jpeg") // you can also check, if the content matches a specific type $bool = $sniffer->matches(new ImageJpeg); // or check, if the content matches an array of types $bool = $sniffer->matches([ImageJpeg::class, ImageGif::class]); // or check, if the content matches an array of type objects $bool = $sniffer->matches([new ImageJpeg, $type]);
If your prefer non-static initialization:
use Intervention\MimeSniffer\MimeSniffer; // create instance with constructor $sniffer = new MimeSniffer($content); // with setter for given content $type = $sniffer->setFromString($other_content)->getType(); // or with setter for filename $type = $sniffer->setFromFilename('images/image.jpg')->getType();
Currently only the following file types can be detected. More will be added in a next release.
