What are common issues when using the rename function in PHP to change file names?

One common issue when using the rename function in PHP to change file names is that the function may fail if the destination file already exists. To solve this issue, you can first check if the destination file exists and remove it before renaming the file. 

$sourceFile = 'source.txt';
$destinationFile = 'destination.txt';

if (file_exists($destinationFile)) {
    unlink($destinationFile);
}

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