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

The opendir() function is used to open a directory handle.
The opendir() function always returns a directory handle resource on succes and return FALSE on failure.

syntax of opendir() function

opendir(path,context);

path is a required parameter
context is a required optional

you can see below example:

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