php包括不同文件夹和子文件夹的所有图像

Question

The following script works:

$dir = "images/";
$images = glob($dir."*.jpg" );
foreach( $images as $image ):

  echo"<li><img src='". '/' . $image . "' /></li>";
endforeach;

Problem is in the PHP script below.Not including more directories where pictures are present

$dir = "images/images2/";
$images = glob($dir."*.jpg" );
foreach( $images as $image ):

       echo"<li><img src='". '/' . $image . "' /></li>";
endforeach;

how to resolve this problem.

Answer 1

Try to use RecursiveIteratorIterator in combination with RecursiveDirectoryIterator

$path = realpath('/path/you/want/to/search/in');

$objects = new RecursiveIteratorIterator(
               new RecursiveDirectoryIterator($path), 
               RecursiveIteratorIterator::SELF_FIRST);

foreach($objects as $name => $object){
    if($object->getFilename() === '*.jpg') {
        echo $object->getPathname();
    }
}
