What potential pitfalls should be considered when attempting to transfer files directly between webspaces with PHP?

When transferring files directly between webspaces with PHP, potential pitfalls to consider include security vulnerabilities such as allowing unauthorized access to sensitive files, potential for file corruption during transfer, and the risk of overloading server resources if transferring large files. 

// Example code snippet to transfer files between webspaces securely
$sourceFile = '/path/to/source/file.txt';
$destinationFile = '/path/to/destination/file.txt';

if (file_exists($sourceFile)) {
    if (is_readable($sourceFile)) {
        if (copy($sourceFile, $destinationFile)) {
            echo 'File transferred successfully.';
        } else {
            echo 'Error transferring file.';
        }
    } else {
        echo 'Source file is not readable.';
    }
} else {
    echo 'Source file does not exist.';
}
