php scan_it以排除以下划線開頭的目錄

Question

我有以下代碼，它掃描指定的目錄中的jpgs：

<?php
$scan_it = new RecursiveDirectoryIterator("images/" . $this->item->extraFields->PropertYID->value . "");

foreach(new RecursiveIteratorIterator($scan_it) as $file) {
if (strtolower(substr($file, -4)) == ".jpg" &&
strtolower(substr($file, -4)) == ".jpg") {

echo '<div><img src="'.$file .'" alt="" />'."</div>";
}
}
?>

我只想在此掃描中排除任何名稱以下划線（_）開頭的文件夾。

澄清目錄結構是否如下：

/images/interior/

/images/exterior/

/images/_room1/

/images/room2/

/images/room3/

將包括除_room1之外的所有目錄。

提前謝謝了！

您可以在文件夾名稱中搜索“_”

$directory = "images/' . $this->item->extraFields->PropertYID->value '";
        $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory), RecursiveIteratorIterator::CHILD_FIRST);
    foreach($files as $name => $file){
        if(is_dir($file)){ //Edited
             $pos = strpos($file, '_');
        }
         if($pos === false){
            if (strtolower(substr($file, -4)) == ".jpg" &&
            strtolower(substr($file, -4)) == ".jpg") {

            echo '<div><img src="'.$file .'" alt="" />'."</div>";
            }
          }
    }

如果你想刪除只有第一個字符為'_'的目錄，如果它在中間，那就ok了，那么你可以這樣做

    $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory), RecursiveIteratorIterator::CHILD_FIRST);
foreach($files as $name => $file){
    if(is_dir($file)){
         $pos = strpos($file, '_');
    }
     if(($pos === false) || $pos>0){
        if (strtolower(substr($file, -4)) == ".jpg" &&
        strtolower(substr($file, -4)) == ".jpg") {

        echo '<div><img src="'.$file .'" alt="" />'."</div>";
        }
      }
}
