What potential issues can arise when trying to create a text file on a server using PHP?

One potential issue that can arise when creating a text file on a server using PHP is insufficient file permissions. To solve this, you need to ensure that the directory where you want to create the file has the correct permissions set to allow PHP to write to it. 

// Check if the directory has the correct permissions
if (!is_writable('/path/to/directory')) {
    echo 'Directory is not writable';
} else {
    // Create a new text file
    $file = fopen('/path/to/directory/newfile.txt', 'w');
    fwrite($file, 'Hello, world!');
    fclose($file);
    echo 'File created successfully';
}
