Hello all,
I wanted to know if anyone knows how to truncate a string with HTML code in it. I need to truncate the string to various characters but I dont want to count the html tags. Is this possible?
my truncate script as is
function truncate_string($string, $max_length){
if (strlen($string) > $max_length) {
$string = substr($string,0,$max_length);
$string .= '...';
}
return $string;
}thanks

I have a form that uses a WYSIWYG text editor, so certain tags are in html format and stored into mysql. I then post that to another page, but if the text is to long I need to truncate it but I don't want the php script to count the html tags just the actual text the user typed in.
Stripping all tags would take away the format of how it will be displayed.
You're missing what I said. If you do:
$some_other_var = strip_tags($_POST['text']);Then $some_other_var will have the text the user wrote. From there, you can count the characters and stop after $length:
$some_other_var = substr($some_other_var, 0, $len);Now, you just need to find the instance of that in your original var...
// Use the last 10 characters.... you could shorten this if you'd like
$position = strpos($_POST['text'], substr($some_other_var, -10));if($position === false)
die('Error finding sub-string');[/code]
Once you have the position, you can then cut the original string there:
$cut_text = substr($_POST['text'], 0, $position);Then you just need to go through and find all the opening tags, and then find their closing tags (if applicable). Things you need to watch out for are <img> tags (which don't have a closing tag) and those that are empty. So you'd need to find all tags that don't have a "/>" as the last two characters. Then you'd just need to have as many closing tags of that element that you do the opening.
You still preserve the text, but you just use other variables to do the "chopping".
I realize that this is a little late but thought you might have some interest in spinning and truncating your article for web usage so that you don't cut it off in the middle of a sentence or paragraph and that you will get a good uniqueness of over 30% on a consistent basis without having to redo your articles every week.
Should someone come up with changes or a better way to handle this please do...Otherwise I hope you like what I put together and found..

$string : The original string to truncate
$limit : The number words to truncate to, may well be over a little due to it ending on the paragraph boundary and not the word boundary.

I did notice, which is why I mentioned that I was sorry I was a bit late, but with the other items I gave, I was thinking that it would be a benefit to others that are just now having the same problem as I did.
well.... IMHO that is silly...3 years...... either way bpats example is good.
one thing though. be sure to use the PHP tags when posting.
they could have
echo strip_tags($text, '<img><table>');
Next time I will...
