In what scenarios would changing the working directory using chdir() be recommended for PHP scripts?

Changing the working directory using chdir() in PHP scripts can be recommended when you need to access files or resources located in a different directory than the default one. This can be useful when working with file uploads, including external libraries, or organizing project files in a specific directory structure. 

<?php
// Change the working directory to a specific folder
chdir('/path/to/directory');

// Now you can access files or resources in the new directory
$file = 'example.txt';
if (file_exists($file)) {
    echo "File exists!";
} else {
    echo "File not found.";
}
?>
