我需要创建一个循环遍历子目录中的所有文件。你能帮我这样构造我的代码吗：
$main = "MainDirectory";
loop through sub-directories {
loop through filels in each sub-directory {
do something with each file
}
};
【问题讨论】：
将RecursiveDirectoryIterator 与 RecursiveIteratorIterator 结合使用。
$di = new RecursiveDirectoryIterator('path/to/directory');
foreach (new RecursiveIteratorIterator($di) as $filename => $file) {
echo $filename . ' - ' . $file->getSize() . ' bytes <br/>';
}
【讨论】：
$file 是SplFileInfo 的一个实例，以及随之而来的方法（getBasename、getSize 等） - 花了我一点时间同时弄清楚这一点。
$file->isDir、$file->isDot也很有用。
您需要添加递归调用的路径。
function readDirs($path){
$dirHandle = opendir($path);
while($item = readdir($dirHandle)) {
$newPath = $path."/".$item;
if(is_dir($newPath) && $item != '.' && $item != '..') {
echo "Found Folder $newPath<br>";
readDirs($newPath);
}
else{
echo ' Found File or .-dir '.$item.'<br>';
}
}
}
$path = "/";
echo "$path<br>";
readDirs($path);
【讨论】：
您可能希望为此使用递归函数，以防您的子目录有子子目录
$main = "MainDirectory";
function readDirs($main){
$dirHandle = opendir($main);
while($file = readdir($dirHandle)){
if(is_dir($main . $file) && $file != '.' && $file != '..'){
readDirs($file);
}
else{
//do stuff
}
}
}
没有测试代码，但这应该接近你想要的。
【讨论】：
while($file = readdir($dirHandle){，否则完美！谢谢。
我喜欢带有通配符的glob：
foreach (glob("*/*.txt") as $filename) {
echo "$filename\n";
}
Details and more complex scenarios.
但如果您的文件夹结构复杂，RecursiveDirectoryIterator 绝对是解决方案。

【讨论】：
另一种解决方案读取子目录和子文件（设置正确的文件夹名称）：
<?php
$path = realpath('samplefolder/yorfolder');
foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path)) as $filename)
{
echo "$filename <br/>";
}
?>

如果我们可以安全地删除任何名为 .或..
function readDirs($path){
$dirHandle = opendir($path);
while($item = readdir($dirHandle)) {
$newPath = $path."/".$item;
if (($item == '.') || ($item == '..')) {
continue;
}
if (is_dir($newPath)) {
pretty_echo('Found Folder '.$newPath);
readDirs($newPath);
} else {
pretty_echo('Found File: '.$item);
}
}
}
function pretty_echo($text = '')
{
echo $text;
if (PHP_OS == 'Linux') {
echo "\r\n";
}
else {
echo "</br>";
}
}
