计算从一个月内用php创建的文件

Question

I managed to count files in a folder with php.

count(scandir($snap_folder))

But now I would need to count only files created in the last 30 days and return the number.

this code returns always 0 even if I have files in the folder ?

 <?php
$snap_user = $_POST['snap_user'];
if (!file_exists($snap_user)){mkdir($snap_user, 0755, true);};
$snap_folder = $snap_user . '/';

$files = scandir($snap_folder);

$limit = date('Y-m-d', strtotime('-30 days'));
$count = 0;
foreach($files as $file) {
    if (date ("Y-m-d", filemtime($file)) >= $limit && !in_array($file, array('.', '..'))) {
        $count++;
    }
}

echo $count
?>

Is it possible?

Answer 1

The code should look something like that

$files = scandir('folder/');

$limit = date('Y-m-d', strtotime('-30 days'));
$count = 0;
foreach($files as $file) {
  if (date ("Y-m-d", filemtime($file)) >= $limit) {
    $count++;
  }
}

EDIT:

$files = scandir('folder/');      
$limit = date('Y-m-d', strtotime('-30 days'));
$count = 0;
foreach($files as $file) {
    if (date ("Y-m-d", filemtime($file)) >= $limit && !in_array($file, array('.', '..'))) {
        $count++;
    }
}

EDIT 2:

$folder = './folder/';
$files = scandir($folder);      
$limit = date('Y-m-d', strtotime('-30 days'));
$count = 0;
foreach($files as $file) {
    $filename = $folder . $file;
    if (date ("Y-m-d", filemtime($filename)) >= $limit && !in_array($file, array('.', '..'))) {
        $count++;
    }
}
echo $count;
