Hi Reader's,
Welcome to FindNerd, today we are going to discuss how to use readdir() function in php ?

The readdir() function is used for returning the name of the next entry in a directory.
This function returns the filename on success and return FALSE on failure.

syntax of readdir() function

  readdir(dir_handle);

dir_handle is a optional parameter

you van see below example:

<?php
//here define dir which die you want to read
  $dir = "img";
  // Open a directory, and read its contents
  if (is_dir($dir)){
    if ($getDir = opendir($dir)){
      while (($file = readdir($getDir)) !== false){
        //here print file file name
        echo "filename:" . $file . "<br>";
      }

      //here close dir
      closedir($getDir);
    }
  }
?>

The output of the code above will be:

filename:zoom-out.png
filename:4.png
filename:zoom-in.png
filename:edit.png
filename:delete.png
