using php to get two even columns of text

Does anyone know a clever way to create even columns of text using php开发者_Go百科?

So lets say I have a few paragraphs of text and I want to split this into two columns of even length (not string length, I'm talking even visible length).

At the moment I'm splitting based on word count, which (as you can imagine) isn't working too well. For instance, on one page I have a list (ul li style) which is increasing the line breaks but not the word count. eg: whats happening is that the left column (with the list in it) is visibly longer than the right column (and if there was a list in the right hand column then it would be the same the other way round).

So does anyone have a clever way to split text? For instance using my knowledge of objective c there is a "size that fits" function. I know how wide the columns are going to be, so is there any way to take that, and the string, and work out how high its going to be? Then cut it in half? Or similar?

Thanks

ps: no css3 nonsense please, we're targeting browsers as far back as ie6 (shudder). :)

I know you're looking at a PHP solution but since the number of lines will depend on how it's rendered in the browser, you'll need to use some javascript.

You basically need to know the dimensions of the container the text is in and using the height divided by the text's line-height, you'll get the number of lines.

Here's a fiddle using jQuery: http://jsfiddle.net/bh8ZR/

There is not a lot of information here as to the source data. However, if you know that you have 20 lines of data, and want to split it, why not simply use an array of the display lines, then divide by two. Then you can take the first half of the PHP array and push it into the second column when you hit the limit of the first.

I think you're going to have trouble displaying these columns in a web browser and having a consistent look and feel because you're trying to apply simple programming logic to a visual layout. CSS and jQuery were designed to help layout issues. jQuery does have IE6 compatibility.

I really don't think you're going to find a magic bullet here if you have HTML formatting inside the data you're trying to display. The browser is going to render this based on a lot of variables. Page width, font size, etc. This is exactly why CSS and other layout styles are there, to handle this sort of formatting.

Is there any reason why you're not trying to solve this in the browser instead of PHP? IE6 to me is not a strong enough case not to do this where it belongs.
