If you want to split on any of the characters which are considered

special by regular expressions, you'll need to escape them first. If

you think <span class="function"><strong>spliti()</strong></span> (or any other regex function, for

that matter) is doing something weird, please read the file

<var class="filename">regex.7</var>, included in the

<var class="filename">regex/</var> subdirectory of the PHP distribution. It's

in manpage format, so you'll want to do something along the lines of

|
<strong class="command">man /usr/local/src/regex/regex.7</strong> in order to read it.
