Answer 1

What about the htmlspecialchars() function?

htmlspecialchars($input, ENT_QUOTES | ENT_XML1, $encoding);

Note: the ENT_XML1 flag is only available if you have PHP 5.4.0 or higher.

htmlspecialchars() with these parameters replaces the following characters:

• & (ampersand) becomes &
• " (double quote) becomes "
• ' (single quote) becomes '
• < (less than) becomes <
• > (greater than) becomes >

You can get the translation table by using the get_html_translation_table() function.
