What potential pitfalls should be considered when trying to save HTML code in a file using PHP?

One potential pitfall when saving HTML code in a file using PHP is that special characters within the HTML code may not be properly escaped, leading to syntax errors or unexpected behavior when the file is later opened or executed. To avoid this issue, it's important to properly escape the HTML code before saving it to the file. 

$htmlCode = "<html><head><title>Example</title></head><body><h1>Hello, World!</h1></body></html>";

// Escape HTML code before saving to file
$escapedHtmlCode = htmlspecialchars($htmlCode);

// Save escaped HTML code to a file
file_put_contents('saved_html.html', $escapedHtmlCode);
