Note Submitter: www.bitcetera.com (-sven) ---- (Please ignore my post further down, it is buggy.) This is a different approach to convert html entities while honoring tags. Given the following: $string = "this is <b>a test</b> for tags & stuff like < this and <> that"; Now you want to have the &, <, > encoded while "a test" should remain in bold. Dodge this: $encoded = implode('', preg_replace('/^([^<].+[^>])$/e', "htmlentities('\\1')", preg_split('/(<[^<]+>)/', $string, -1, PREG_SPLIT_DELIM_CAPTURE))); It returns: $encoded = "this is <b>a test</b> for tags &amp; stuff like &lt; this and &lt;&gt; that"; This way, < and > not belonging to tags are encoded. However, as this line of code does not actually check if a valid HTML keyword is between the < and >, the string "5 is < than 7 and not > 9" will not be encoded, as " than 7 and not " is falsely taken for a HTML tag.
