How does the use of mb_internal_encoding() impact the output when reading files from a ZipArchive in PHP?

When reading files from a ZipArchive in PHP, the use of mb_internal_encoding() can impact the output by ensuring that the correct character encoding is used when reading and displaying text files. This function sets the internal character encoding to the specified encoding, which can prevent issues with displaying special characters or non-ASCII characters incorrectly. 

// Set the internal character encoding to UTF-8
mb_internal_encoding('UTF-8');

// Open the Zip file
$zip = new ZipArchive;
if ($zip->open('example.zip') === TRUE) {
    // Read the contents of a text file from the Zip archive
    $content = $zip->getFromName('example.txt');
    
    // Output the content with the correct character encoding
    echo $content;
    
    $zip->close();
} else {
    echo 'Failed to open the Zip file.';
}
