"; $fileLines = file($dataFile); foreach ($fileLines as $line) { echo "

" . htmlspecialchars(trim($line)) . "

"; } echo "

"; foreach ($fileLines as $line) { $name = str_replace("Artist Profile: ", "", trim($line)); $artist = new MusicCreator($name); echo "

" . $artist->displayInfo() . "

"; } echo "
