php获取文件夹下所有文件，包含子文件夹
2015-12-17
PHP
/**
* 获取文件夹下所有文件
* @param $directory 需要获取的文件夹
* @param bool $recursive 是否递归获取子文件夹
* @return array
*/
function directoryToArray($directory, $recursive = false) {
$array_items = array();
if(!is_dir($directory)) return "$directory folder does not exist";
if ($handle = opendir($directory)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
if (is_dir($directory. "/" . $file)) {
if($recursive) {
$array_items = array_merge($array_items, directoryToArray($directory. "/" . $file, $recursive));
}
$file = $directory . "/" . $file;
$array_items[] = preg_replace("/\/\//si", "/", $file);
} else {
$file = $directory . "/" . $file;
$array_items[] = preg_replace("/\/\//si", "/", $file);
}
}
}
closedir($handle);
}
return $array_items;
}
//调用
$files = directoryToArray('../project/353438199e',true);
var_dump($files);
php5.3新增了一些新的方法来实现，如RecursiveIteratorIterator 、scandir。
