counting tags and writing missing tags

Threaded View
sometimes people just forget to close formating tag while writing
message in forum (or enywhere else) so I wrote those lines (for <b>, <i>
and <a> tags)

$i_open = substr_count($tekst, "<i>");
$i_close = substr_count($tekst, "</i>");
if($i_open > $i_close) {
  $tekst = "$tekst </i>";

but... I would like to have proper nesting, ie: if someone write
"<b>some text <i>without closing tags"
and if my script have order like
if($b_open > $b_close)
if($i_open > $i_close)
if($a_open > $a_close)

I will have unproper nesting:
"<b>some text <i>without closing tags </b> </i>"

Is there some method to "see" which tag should came first?

Don't use flags. They won't be of any use if tags of the same type are
nested (e.g., "<b><b>...</b>").

Instead, use a stack to keep a record of which tags are open.

These functions should help:
