Word Wraping

james2010

I know there's a function out there (wordwrap()) that wraps text, but is there anything that will do that ignoring html tags or vb type tags [tag][/tag]? I've searched around without luck, so I think I'll probably have make one myself. Unfortunately every attempt I've made has lead me into complex confusing regular expressions. Any ideas on how I should go about doing this?

Have you combined it with strip_tags()?

Hmm, about those [tags], I dunno; but str_replace is much easier than regexps, generally. But you'd have to know what tags were gonna be there, right?

Oh, well...:rolleyes:

Looky here:

<?

$text="this is[blah] my[/blah] text";
$text=str_replace("]", ">", $text);
$text=str_replace("[", "<", $text);
$text=strip_tags($text);
echo "<br><br>$text";

?>

Humm... it works thanks 😃. But then what happens when you want to display formatted word wrapped text. When you strip the tags is there any way of getting them back in after you've done a word wrap? LOL an unstrip_tags() ?😉

You gotta decide what you wanna keep and what you wanna throw out.

Or, you could copy the $var and have one stripped and one, um "clothed"?

I dunno really what you're asking for, and I'm no guru....

ok well I'll have text like this that I pull from a query.....

$str = "[tag1]text text text text[/tag1] text text text text text text[tag2="text"]text text[/tag2] text text";

and I want to feed this through a word wrapping function and end up with something like this

$str = "[tag1]text text text text[/tag1]<br>
text text text text<br>
text text [tag2="text"]text text[/tag2]<br>
text text";

Thus to the viewer the lines appear to be wrapped to the same length rather than wrapped according the the lenght including the tags. So I think one way I could do this is by using a regular expression to extract all the tags the compare and record the position of each tag, send the tagless string through wordwrap, then feed the tags back into it.

It seems like it might get a little messy so I was trying to find an easier way of doing it.
