The **`rmdir()`** function in PHP removes an empty directory.

# Syntax
```c
rmdir(string $path, resource $context = ?): bool
```

# Parameters

`path`: This specifies the path of the directory we want to remove.

`context`: This is an optional parameter that specifies the context of the file handle. It is a set of options that modify the system's behavior.


# Return value

`rmdir()` returns `true` if the directory is removed successfully. Otherwise, in case of any error, it returns `false`.

# Code

The following code shows how to use the `rmdir()` function.

<?php
mkdir("documents");

if(rmdir("documents")) 
{
  echo ("Directory removed");
}
?>

## Explanation 
In the code above, a directory named `documents` is created. It is then removed successfully using the `rmdir` function since it is an empty directory.
