如何计算文件夹中已存在的文件数

Question

在文件管理中,为了将文件移动到另一个文件夹,我试图计算文件夹中已存在的文件数.

foreach($checkboxfiles as $checkboxfile) {
    $src_file = $checkboxfile;
    $fileName = basename($src_file);
    $new_dest = $_POST['cbdestination'];

    /* New path for this file */
    $dest_file = $MainFolderName.'/'. $new_dest . '/' . $fileName;

    echo count(file_exists($dest_file)); //this should give me the number of files which already exists

由于2个文件已存在,因此回声产生

11
11

作为输出.我如何实现2输出数量？

你count错了.file_exists返回true或false.count用于计数arrays.为了达到你想要的目的,你可以做到:

$count = 0;  
foreach($checkboxfiles as $checkboxfile) {
    $src_file = $checkboxfile;
    $fileName = basename($src_file);
    $new_dest = $_POST['cbdestination'];

    /* New path for this file */
    $dest_file = $MainFolderName.'/'. $new_dest . '/' . $fileName;
    if(file_exists($dest_file)){
        $count++;
    }
}
echo $count;
