How to count number of files in folder in php? - php

Question

I want to enable users to upload some files (pictures) in their own folders. But that should be possible only if that folders contain less than five pictures. If there are 5 pictures already, script has to let know user that his/her folder is full.
So, I wonder if there is function in php that count number of files in folder. Or any other way in php to do that? Thanks in advance.

Answer 1

Use the FilesystemIterator as shown:
$dir = "/path/to/folder";
$fi = new FilesystemIterator($dir, FilesystemIterator::SKIP_DOTS);
$fileCount = iterator_count($fi);

Answer 2

Nothing easier: use opendir() and readdir() just like follow:
<?php
$images_extension_array = array("jpg","jpeg","gif","png");
$dir = "/path/to/user/folder";
$dir_resource = opendir($dir);
$file_count = 0;
while (($file = readdir($dir_resource)) !== false) { // scan directory
$extension_from = strrpos($file,"."); // isolate extension index/offset
if ($extension_from && in_array(substr($file,$extension_from+1), $images_extension_array))
$file_count ++; //if has extension and that extension is "associated" with an image, count
}
if ($number_of_files == %) {
//do stuff
}
Obviously this doesn't take into account file extensions...
You can also use:
scandir() ---> read here
FilesystemIterator class (as dops's answer correctly suggest) ---> read here

Answer 3

You could just let PHP find the files for you...then count them.
$count = count(glob("$path_to_user_dir/*"));

Answer 4

I really like dops answer, but it will return the count of files, directories, and symlinks, which may not be the goal. If you just want a count of the local files in a directory, you can use:
$path = "/path/to/folder";
$fs = new FilesystemIterator($path);
foreach($fs as $file) {
$file->isFile() ? ++$filecount : $filecount;
}

This little function here is a modification to some code I found a little while ago that will also count all of the sub Folders and everything in those folders as well:
<?PHP
$folderCount = $fileCount = 0;
countStuff('.', $fileCount, $folderCount);
function countStuff($handle, &$fileCount, &$folderCount)
{
if ($handle = opendir($handle)) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != "..") {
if (is_dir($entry)) {
echo "Folder => " . $entry . "<br>";
countStuff($entry, $fileCount, $folderCount);
$folderCount++;
} else {
echo "File => " . $entry . "<br>";
$fileCount++;
}
}
}
closedir($handle);
}
}
echo "<br>==============<br>";
echo "Total Folder Count : " . $folderCount . "<br>";
echo "Total File Count : " . $fileCount;
?>
NOTE: I will also post the original code that will just count the files and folders of the parent directory and not the sub-folders children below:
if ($handle = opendir('.')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != "..") {
if (is_dir($entry)) {
echo "Folder => " . $entry . "<br>";
countStuff($entry, $fileCount, $folderCount);
$folderCount++;
} else {
echo "File => " . $entry . "<br>";
$fileCount++;
}
}
}
echo "<br>==============<br>";
echo "Total Folder Count : " . $folderCount . "<br>";
echo "Total File Count : " . $fileCount;
closedir($handle);
}

Answer 6

You can use
$nbFiles=count(scandir('myDirectory'))-2;
(-2 is for removing "." and "..")
