strip_tags -- Strip HTML and PHP tags from a string
Description
string strip_tags (string str [, string allowable_tags])
This function tries to return a string with all HTML and PHP tags
stripped from a given str. It errors on the side of caution in case
of incomplete or bogus tags. It uses the same tag stripping state
machine as the fgetss() function.
You can use the optional second parameter to specify tags which
should not be stripped.
