How can renaming a directory in PHP resolve issues related to reading files within that directory?

When renaming a directory in PHP, it can resolve issues related to reading files within that directory because the file paths might be hardcoded with the old directory name. By renaming the directory, the file paths will be updated to reflect the new directory name, allowing the PHP script to locate and read the files correctly. 

// Rename the directory
$oldDir = 'old_directory';
$newDir = 'new_directory';
if (rename($oldDir, $newDir)) {
    echo 'Directory renamed successfully.';
} else {
    echo 'Error renaming directory.';
}
