If i have a word like c.........a......t (with the dots in) and i wanted to replace it with cat how would i do it. If i use

CODE

<?php
$patterns = "/c(*)a(*)t/";
$replace = "cat";
echo preg_replace($patterns, $replace, 'c.....a.........t');
[/color][color="#000000"]?>

then when i type something like "come and look at this" is also filtered. Is there any way just to filter cat with dots in?

If all you want to do is eliminate dots found specifically inbetween the letters "c", "a" and "t", then the following should work:

CODE

$patterns = "/c\.{2,}a\.{2,}t/";
$replace = "cat";
echo preg_replace($patterns, $replace, 'c.....a.........t');

Anything else would require a more complex pattern.

Replace Shtml With Php? - I don't know jack.... (1)

I don't know anything about PHP, except that I use phpBB and have modified my forums template
files. I used to make web sites years ago and just got back into it a couple months ago. I wonder
if I should stop using shtml and switch to php. I don't really have time to learn php (at least
not yet), but if it's easy to replace my Server Side Include with php (just to be more "modern")
I would be willing to do so. Anyone have any suggestions about me doing so? Am I'm too old
school for using shtml? Lol /laugh.gif' border='0' style='vertical-align:middle' ...
