GlobIterator::__construct — Construct a directory using glob
$pattern, int $flags = FilesystemIterator::KEY_AS_PATHNAME | FilesystemIterator::CURRENT_AS_FILEINFO)Constructs a new directory iterator from a glob expression.
patternA glob() pattern.
flagsOption flags, the flags may be a bitmask of the FilesystemIterator constants.
Throws an UnexpectedValueException
if the directory does not exist.
Throws a ValueError
if the directory is an empty string.

Now throws a ValueError if

Example #1 GlobIterator example
<?php
$iterator = new GlobIterator('*.dll', FilesystemIterator::KEY_AS_FILENAME);
if (!$iterator->count()) {
echo 'No matches';
} else {
$n = 0;
printf("Matched %d item(s)\r\n", $iterator->count());
foreach ($iterator as $item) {
printf("[%d] %s\r\n", ++$n, $iterator->key());
}
}
?>The above example will output something similar to:
Matched 2 item(s) [1] php5ts.dll [2] php_gd2.dll
