note 68661 deleted from function.strip-tags by danbrown

Note Submitter: elgios at gmail dot com ---- I think that the new function works, but don't remove PHP tags, only html!! <?php function theRealStripTags2($string) { $tam=strlen($string); // tam have number of cars the string $newstring=""; // newstring will be returned $tag=0; /* if tag = 0 => copy car from string to newstring if tag > 0 => don't copy. Found one or more '<' and need to search '>'. If we found 3 '<' need to find all the 3 '>' */ /* I am C programmer. walk in a string is natural for me and more efficient */ for ($i=0; $i < $tam; $i++){ // If I found one '<', $tag++ and continue whithout copy if ($string{$i} == '<'){ $tag++; continue; } // if I found '>', decrease $tag and continue if ($string{$i} == '>'){ if ($tag){ $tag--; } /* $tag never be negative. If string is "<b>test</b>>" (error, of course) $tag will stop in 0 */ continue; } // if $tag is 0, can copy if ($tag == 0){ $newstring .= $string{$i}; // simple copy, only one car } } return $newstring; } echo theRealStripTags2("<tag>test</tag>"); // return "test" ?>
