When visitors leave messages and posts, we do not want visitors to use html tags in their messages and posts, so we have to delete the html tags when visitors submit messages and posts. The following function is the function that implements this function
function delete_htm($scr)
{
for($i=0;$i
if(substr ($scr,$i,1)=="<")
{
while(substr($scr,$i,1)!=">")$i++;
$i++ ;
}
$str=$str.substr($scr,$i,1);
}
return($str);
}
?>
