[英]PHP read sub-directories and loop through files how to?
我需要通過子目錄中的所有文件創建一個循環。 你能幫我這樣構造我的代碼嗎:
$main = "MainDirectory";
loop through sub-directories {
loop through filels in each sub-directory {
do something with each file
}
};
將RecursiveDirectoryIterator與RecursiveIteratorIterator結合使用。
$di = new RecursiveDirectoryIterator('path/to/directory');
foreach (new RecursiveIteratorIterator($di) as $filename => $file) {
echo $filename . ' - ' . $file->getSize() . ' bytes <br/>';
}
如果你的子目錄有子目錄,你可能想要使用遞歸函數
$main = "MainDirectory";
function readDirs($main){
$dirHandle = opendir($main);
while($file = readdir($dirHandle)){
if(is_dir($main . $file) && $file != '.' && $file != '..'){
readDirs($file);
}
else{
//do stuff
}
}
}
沒有測試代碼,但這應該接近你想要的。
您需要添加遞歸調用的路徑。
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);
我喜歡帶有通配符的glob
:
foreach (glob("*/*.txt") as $filename) {
echo "$filename\n";
}
但是,如果你有一個復雜的文件夾結構, RecursiveDirectoryIterator
絕對是解決方案。
使用子目錄和子文件讀取的另一個解決方案 (設置正確的foldername):
<?php
$path = realpath('samplefolder/yorfolder');
foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path)) as $filename)
{
echo "$filename <br/>";
}
?>
<?php
ini_set('max_execution_time', 300); // increase the execution time of the file (in case the number of files or file size is more).
class renameNewFile {
static function copyToNewFolder() { // copies the file from one location to another.
$main = 'C:\xampp\htdocs\practice\demo'; // Source folder (inside this folder subfolders and inside each subfolder files are present.)
$main1 = 'C:\xampp\htdocs\practice\demomainfolder'; // Destination Folder
$dirHandle = opendir($main); // Open the source folder
while ($file = readdir($dirHandle)) { // Read what's there inside the source folder
if (basename($file) != '.' && basename($file) != '..') { // Ignore if the folder name is '.' or '..'
$folderhandle = opendir($main . '\\' . $file); // Open the Sub Folders inside the Main Folder
while ($text = readdir($folderhandle)) {
if (basename($text) != '.' && basename($text) != '..') { // Ignore if the folder name is '.' or '..'
$filepath = $main . '\\' . $file . '\\' . $text;
if (!copy($filepath, $main1 . '\\' . $text)) // Copy the files present inside the subfolders to destination folder
echo "Copy failed";
else {
$fh = fopen($main1 . '\\' . 'log.txt', 'a'); // Write a log file to show the details of files copied.
$text1 = str_replace(' ', '_', $text);
$data = $file . ',' . strtolower($text1) . "\r\n";
fwrite($fh, $data);
echo $text . " is copied <br>";
}
}
}
}
}
}
static function renameNewFileInFolder() { //Renames the files into desired name
$main1 = 'C:\xampp\htdocs\practice\demomainfolder';
$dirHandle = opendir($main1);
while ($file = readdir($dirHandle)) {
if (basename($file) != '.' && basename($file) != '..') {
$filepath = $main1 . '\\' . $file;
$text1 = strtolower($filepath);
rename($filepath, $text1);
$text2 = str_replace(' ', '_', $text1);
if (rename($filepath, $text2))
echo $filepath . " is renamed to " . $text2 . '<br/>';
}
}
}
}
renameNewFile::copyToNewFolder();
renameNewFile::renameNewFileInFolder();
?>
$allFiles = [];
public function dirIterator($dirName)
{
$whatsInsideDir = scandir($dirName);
foreach ($whatsInsideDir as $fileOrDir) {
if (is_dir($fileOrDir)) {
dirIterator($fileOrDir);
}
$allFiles.push($fileOrDir);
}
return $allFiles;
}
如果我們可以安全地刪除任何已命名的項目,對John Marty發布的內容進行微小修改。 要么 ..
function readDirs($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>";
}
}
