SplFileInfo::setInfoClass

Use this method to set a custom class which will be used when SplFileInfo::getFileInfo() and SplFileInfo::getPathInfo() are called. The class name passed to this method must be SplFileInfo or a class derived from SplFileInfo .

Parameters

Return Values

Examples

// Define a class which extends SplFileInfo
class MyFoo extends SplFileInfo <>

$info = new SplFileInfo ( ‘foo’ );
// Set the class name to use
$info -> setInfoClass ( ‘MyFoo’ );
var_dump ( $info -> getFileInfo ());
?>

The above example will output something similar to:

User Contributed Notes 1 note

Be careful when using this method, as the functionality isn’t exactly the same as instantiating the extending class directly. This can really trip you up if you’re using type hints or instanceof checks.

class CustomFileInfo extends SplFileInfo
public function getExtension ()
$ext = strtolower ( parent :: getExtension ());

return ‘jpeg’ === $ext ? ‘jpg’ : $ext ;
>
>

$path = __DIR__ . ‘/foobar.jpeg’ ;

$good = new CustomFileInfo ( $path );

echo «» ;
var_dump ( $good instanceof SplFileInfo );
var_dump ( $good instanceof CustomFileInfo );

$bad = new SplFileInfo ( $path );
$bad -> setInfoClass ( ‘CustomFileInfo’ );

var_dump ( $bad instanceof SplFileInfo );
var_dump ( $bad instanceof CustomFileInfo );
echo «» ;

Fileinfo Functions

The results of this function seem to be of dubious quality.

eg
1) a Word doc returns:
‘application/msword application/msword’
. ok not too bad, but why does it come back twice?

3) a text doc that starts with the letters ‘GIF’ comes back as:
‘image/gif’
(just like in DanielWalker’s example for the unix ‘file’ command)

I had better results using the PEAR ‘MIME_Type’ package. It gave proper answers for 1 & 3 and identified the PHP file as ‘text/plain’ which is probably better than a false match for C++

Both finfo_file and MIME_Type correctly identified my other two test files which were a windows exe renamed with .doc extension, and a PDF also renamed with .doc extension.
