I need to create a loop through all files in subdirectories. Can you please help me struct my code like this:
$main = "MainDirectory";
loop through sub-directories {
loop through filels in each sub-directory {
do something with each file
}
};
Use RecursiveDirectoryIterator in conjunction with RecursiveIteratorIterator.
$di = new RecursiveDirectoryIterator('path/to/directory');
foreach (new RecursiveIteratorIterator($di) as $filename => $file) {
echo $filename . ' - ' . $file->getSize() . ' bytes <br/>';
}
$file in the above is an instance of SplFileInfo, with the methods that go along with that (getBasename, getSize, etc) - took me a little while to figure that out.
$file->isDir, $file->isDot are also very usefull.You need to add the path to your recursive call.
function readDirs($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);
You probably want to use a recursive function for this, in case your sub directories have sub-sub directories
$main = "MainDirectory";
function readDirs($main){
$dirHandle = opendir($main);
while($file = readdir($dirHandle)){
if(is_dir($main . $file) && $file != '.' && $file != '..'){
readDirs($file);
}
else{
//do stuff
}
}
}
didn't test the code, but this should be close to what you want.
while($file = readdir($dirHandle){, otherwise works perfect! Thanks.
I like glob with it's wildcards :
foreach (glob("*/*.txt") as $filename) {
echo "$filename\n";
}
Details and more complex scenarios.
But if You have a complex folders structure RecursiveDirectoryIterator is definitively the solution.
Come on, first try it yourself!
What you'll need:
scandir()
is_dir()
and of course foreach
Another solution to read with sub-directories and sub-files (set correct foldername):
<?php
$path = realpath('samplefolder/yorfolder');
foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path)) as $filename)
{
echo "$filename <br/>";
}
?>
Minor modification on what John Marty posted, if we can safely eliminate any items that are named . or ..
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>";
}
}
<?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).

$main = 'C:\xampp\htdocs\practice\demo'; // Source folder (inside this folder subfolders and inside each subfolder files are present.)
