I needed to match in directory tree file name(s) by regular expression. Code is based on Marcus
Börger class DirectoryTreeIterator http://cvs.php.net/viewvc.cgi/php-src/ext/spl/examples/
and on examples given in his lecture Introduction to object oriented PHP at PHP Quebec conference
2007 http://talks.somabo.de/
<?php
class KeyFilter extends FilterIterator
{
private $_rx;
function __construct(Iterator $it, $regex)
{
parent::__construct($it);
$this->_rx= $regex;
}
function accept()
{
return ereg($this->_rx,$this->getInnerIterator()->key());
}
protected function __clone() {
return false;
}
}
class DirMach extends KeyFilter
{
function __construct($path , $regex)
{
parent::__construct(
new DirectoryTreeIterator($path), $regex);
}
function current()
{
return parent::key();
}
function key()
{
return parent::key();
}
}
class DirectoryTreeIterator extends RecursiveIteratorIterator
{
/** Construct from a path.
* @param $path directory to iterate
*/
function __construct($path)
{
try {
parent::__construct(
new RecursiveCachingIterator(
new RecursiveDirectoryIterator($path, RecursiveDirectoryIterator::KEY_AS_FILENAME
),
CachingIterator::CALL_TOSTRING|CachingIterator::CATCH_GET_CHILD
),
parent::SELF_FIRST
);
} catch(Exception $e) {
echo $e->getMessage();
exit;
}
}
/** @return the current element prefixed with ASCII graphics
*/
function current()
{
if ($this->hasChildren())
$this->next();
return $this->key();
}
/** Aggregates the inner iterator
*/
function __call($func, $params)
{
return call_user_func_array(array($this->getSubIterator(), $func), $params);
}
}
$PathToSearch = 'path_to_search';
$regex = 'regular_expression';
$FileList = new DirMach($PathToSearch, $regex);
foreach ($FileList as $file) {
$match[] = $file;
}
echo '<pre>';
var_dump($match);
echo '</pre>';
