Please refer to the Plum documentation for more information about Plum in general.


Plum\PlumFile\FileExtensionFilter checks if the file extension of a file name matches.

use Plum\PlumFile\FileExtensionFilter;

$filter = new FileExtensionFilter('md');
$filter->filter(''); // -> true
$filter->filter('README.html'); // -> false

If the item is are more complex structure, for example, an array or an object FileExtensionFilter uses Symfonys PropertyAccess to retrieve the filename from the item. You can pass the path to the property as the second argument to the constructor.

use Plum\PlumFile\FileExtensionFilter;

$filterArray = new FileExtensionFilter('md', '[filename]');
$filterArray->filter(['filename' => '']); // -> true
$filterArray->filter(['filename' => 'README.html']); // -> false

$item = new stdClass();
$item->filename = '';
$filterObject = new FileExtensionFilter('md', 'filename');
$filterObject->filter($item); // -> true
$item->filename = 'README.html';
$filterObject->filter($item); // -> false

The extension passed to the constructor can also be an array. The filter returns true if the given item matches any of the extensions in the array.

$filter = new FileExtensionFilter(['md', 'html']);
$filter->filter('');   // -> true
$filter->filter('file.html'); // -> false
$filter->filter('file.csv`);  // -> false

Just like the FileExtensionFilter the ModificationTimeFilter uses the Property Access component to retrieve the filename. You can pass the path to the property as second argument to the constructor. The file can be either a string or an instance of SplFileInfo.


The Plum\PlumFile\ModificationTimeFilter returns if a file was modified before and/or after a certain time.

use Plum\PlumFile\ModificationTimeFilter;

$after = new ModificationTimeFilter(['after' => new DateTime('-3 days')]);
$after->filter('modified-2-days-ago.txt'); // -> true
$after->filter('modified-4-days-ago.txt'); // -> false

$before = new ModificationTimeFilter(['before' => new DateTime('-3 days')]);
$before->filter('modified-4-days-ago.txt'); // -> true
$before->filter('modified-2-days-ago.txt'); // -> false

$range = new ModificationTimeFilter(['after' => new DateTime('-6 days'), 'before' => new DateTime('-3 days')]);
$range->filter('modified-4-days-ago.txt'); // -> true
$range->filter('modified-8-days-ago.txt'); // -> false
$range->filter('modified-2-days-ago.txt'); // -> false


The Plum\PlumFile\FileGetContentsConverter takes a SplFileInfo object or a filename and returns the content of the file.

use Plum\PlumFile\FileGetContentsConverter;

$converter = new FileGetContentsConverter();
$converter->convert('foo.txt'); // -> 'content of foo.txt'

If the item is a more complex structure it is possible to define the Vale accessor property for both the filename and the content.

use Plum\PlumFile\FileGetContentsConverter;

$converter = new FileGetContentsConverter('file', 'content');
$converter->convert(['file' => foo.txt']);
// -> ['file' => 'foo.txt', 'content' => content of foo.txt']
