Issue with preg_replace_callback 1

[sen5241b]

Just a little troubleshooting tip: I can't make the callback function used with preg_replace_callback return a blank string (spaces) of certain length. If I try to return a string of say 8 spaces it only returns a string of one space. If I make it return a string of dashes or 'x's of certain length it works fine.

BTW, I have PHP Version 5.2.5.

It does return as many spaces as you want, but HTML (which I suppose you use to output your PHP) is white-space agnostic, which means that it treats as many spaces as you have as a single space. If you look at your HTML source (with view source in the browser) you will notice that all the spaces are there.

If you really want to, you could use the <pre> element to display this part (pre element will maintain the formatting, that it, it will preserve all the white-space as the original text) or output [tt][ignore]&nbsp;[/ignore][/tt] instead of spaces (those are rendered the same as spaces but they do show up in the browser).

However, the question remains... why would you want to output a bunch of spaces. There probably is a better way of doing it.
