Are there any best practices or guidelines to follow when using the copy() function in PHP to avoid unexpected issues like the one described in the forum thread?

Issue: The copy() function in PHP can sometimes fail to copy files due to permission issues. To avoid this, it's best practice to check if the file exists and if the destination directory is writable before attempting to copy the file. Solution: 

$sourceFile = 'path/to/source/file.txt';
$destinationDir = 'path/to/destination/dir/';

if (file_exists($sourceFile) && is_writable($destinationDir)) {
    if (copy($sourceFile, $destinationDir . basename($sourceFile))) {
        echo 'File copied successfully!';
    } else {
        echo 'Failed to copy file.';
    }
} else {
    echo 'Source file does not exist or destination directory is not writable.';
}
