What is the purpose of using opendir() and readdir() functions in PHP?

The opendir() function in PHP is used to open a directory handle, allowing you to read the contents of a directory using the readdir() function. This is useful when you need to programmatically access and manipulate files within a directory. Here is an example of how to use opendir() and readdir() functions in PHP: 

$dir = "/path/to/directory";

// Open a directory handle

// Loop through the directory and read its contents
while (false !== ($file = readdir($handle))) {
    echo $file . "<br>";
}

// Close the directory handle
closedir($handle);
