获取目录中带有过滤器 (第二个参数)的所有文件和文件夹，如果使用.或，请勿调用函数..。

您的代码：

function getDirContents($dir, $filter = '', &$results = array()) {

$files = scandir($dir);

foreach($files as $key => $value){

$path = realpath($dir.DIRECTORY_SEPARATOR.$value);

if(!is_dir($path)) {

if(empty($filter) || preg_match($filter, $path)) $results[] = $path;

} elseif($value != "." && $value != "..") {

getDirContents($path, $filter, $results);

}

}

return $results;

}

// Simple Call: List all files

var_dump(getDirContents('/xampp/htdocs/WORK'));

// Regex Call: List php files only

var_dump(getDirContents('/xampp/htdocs/WORK', '/\.php$/'));

输出(示例)：

// Simple Call

array(13) {

[0]=> string(69) "/xampp/htdocs/WORK.htaccess"

[1]=> string(73) "/xampp/htdocs/WORKConverter.php"

[2]=> string(69) "/xampp/htdocs/WORKEvent.php"

[3]=> string(70) "/xampp/htdocs/WORKdefault_filter.json"

[4]=> string(68) "/xampp/htdocs/WORKdefault_filter.xml"

[5]=> string(80) "/xampp/htdocs/WORKCaching/ApcCache.php"

[6]=> string(84) "/xampp/htdocs/WORKCaching/CacheFactory.php"

}

// Regex Call

array(13) {

[0]=> string(69) "/xampp/htdocs/WORKEvent.php"

[1]=> string(73) "/xampp/htdocs/WORKConverter.php"

[2]=> string(80) "/xampp/htdocs/WORKCaching/ApcCache.php"

[3]=> string(84) "/xampp/htdocs/WORKCaching/CacheFactory.php"
