What potential issue arises from using $filename after the foreach loop in the PHP script?

Using $filename after the foreach loop in the PHP script may result in the variable holding the value of the last iteration of the loop. To avoid this issue, you can store the value of $filename in another variable before the loop and then use that variable after the loop. 

$filenames = ['file1.txt', 'file2.txt', 'file3.txt'];

// Store $filename in another variable before the loop
$originalFilename = $filename;

foreach ($filenames as $filename) {
    // Loop logic here
}

// Now you can safely use $originalFilename after the loop
echo $originalFilename;
