Read one file name "Only" and skip to next directory - PHP

I have the following code which reads all filnames from each directory, but I want it to read one filename "only" and skip to the next directory. 

<?php
$dir = "/images/";

// Open a directory, and read its contents
if (is_dir($dir)){
  if ($dh = opendir($dir)){
    while (($file = readdir($dh)) !== false){
      echo "filename:" . $file . "<br>";
    }
    closedir($dh);
  }
}
?>

How can I read only one filename, then skip to the next directory to read "only" first filename and so on. Please let me know if you require any more information.

if it doesn't matter which file you read then just put a break; in your while loop or don't even go in a loop just take the $file = readdir($dh); PS: In linux OS be aware of . and .. Also look up scabdir() function

You need to maintain counter here to do the same.

Do like this:

$dir = "/images/";

if (is_dir($dir)){
    if ($dh = opendir($dir)){
        while (($file = readdir($dh)) !== false){
        echo "filename:" . $file . "<br>";
        break;
    }
    closedir($dh);
  }
}

Let me know for more help!
