line count & resize

[WCK]

I am a bit of a newbie to PHP, so please take it easy on me! 😛

I made a status signature a while ago. It turned out quite well and people seem to really like it. But now I'm trying to make a new one, but it requires some PHP coding that I don't know about. I need a code that will count the number of lines between 2 lines of an HTML page.

I need a code that will count the amount of lines between the <ul class="clearfix"> and </ul>.

    <ul class="clearfix">
            <li style="background-image: url(http://image.gif)"></li>
            <li style="background-image: url(http://image.gif)"></li>
            <li style="background-image: url(http://image.gif)"></li>
    </ul>

It's a status signature, every line will represent 1 "badge" a person may have. I also need a code that will readjust the size of the image depending on how many badges there are.

Thanks in advance!

If you want us to code it for you I'm sorry but you came to the wrong place.

If you need help to be able to code it yourself this is the place for you.

I suggest that you search for the start tag, then the end tag (starting to search from the start tag). In the string between them it is just to count the number of li-tags and you got the result.

About ajusting the size of the image... just use the count to set different sizes or css classes.

If you have specific questions don't hesitate to post what you have and ask how to solve the problem.

You might want to look into the [man]DOM[/man] functions to parse the document and get your count.

uh... sorry if it seemed like I was asking for someone to write the coding for me. I'm sort of new to PHP and don't know what I'm doing... so I only have a slight idea how to do this. I understand what you mean Piranha, but I wouldn't know to go about writing a code that would do that...

I could really use some help on this. I've tried building a function to count the amount of "<li" tags but it doesn't seem to be working properly.

function count()
    {
        if (eregi('<ul class="clearfix">', $this->data))
      {
        $count = explode('<ul class="clearfix">', $this->data);
        $count = explode('</ul>', $count);
        $count = count('<li', COUNT_RECURSIVE);
        return $count;
    }
       else
    {
       $count = "-";
       return $count;
    }
  }

It is only displaying "1" when there should be many more.

There's likely a slicker way of doing this, but it seems to work:

function count()
{
   preg_match_all('#<ul class="clearfix">.*</ul>#Uis', $this->data, $matches);
   $count = 0;
   foreach($matches[0] as $ul)
   {
      preg_match_all('#<li#i', $ul, $li);
      $count += count($li[0]);
   }
   return $count;
}

woah... I don't even fully understand how that works, but it works! Thank you very much 🙂
