PHP opendir() Function

The PHP opendir() function opens up a directory handle to be used in subsequent readdir(), rewinddir() and closedir() calls.

Syntax

opendir(path, context)

Parameters

`path`	`Required.` Specify the directory path that is to be opened.
`context`	`Optional.` Specify the context of the directory handle. Context is a set of options that can modify the behavior of a stream.

Return Value

Exceptions

Upon failure, an E_WARNING is emitted. This could be due to invalid directory path, permission restrictions, or filesystem errors.

The example below shows the usage of opendir() function.

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

//opens the directory, and read its contents
if (is_dir($dir)){
  if ($dh = opendir($dir)){
    
    //reading all entry from directory handle
    while (($file = readdir($dh)) !== false){
      echo "File Name: ".$file."\n";
    }
    
    //closing the directory handle
    closedir($dh);
  }
}
?>
