regular expressions

regex-style find replace - s/mistake/replacement/ - works in Skype on Mac and Linux for your previous message!

I'm not the first to discover this but discovering it by accident was fun!

Right there in the examples for the php function preg_replace was how to strip whitespace from a string:

<?php
$str = preg_replace('/\s\s+/', ' ', $str);
?>

Ereg replace looks prettier:

<?php
$string = trim(ereg_replace(' +', ' ', $string));
?>

However, Agaric has read in several places that preg_replace tends to be faster.
