What are some common reasons for the rename() function not working as expected in PHP?

One common reason for the rename() function not working as expected in PHP is incorrect file paths or permissions issues. To solve this, double-check the file paths you are using and ensure that the files have the necessary permissions for the rename operation to be successful. 

// Example code snippet to fix rename() function not working as expected
$oldFilePath = '/path/to/old/file.txt';
$newFilePath = '/path/to/new/file.txt';

if (rename($oldFilePath, $newFilePath)) {
    echo "File renamed successfully.";
} else {
    echo "Error renaming file.";
}
