Splits a <parameter>string</parameter> into array by regular expression.

This function is identical to <function>split</function> except that this
ignores case distinction when matching alphabetic characters.

<para>
Case insensitive regular expression.
</para>
<para>
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 <function>spliti</function> (or any other regex function, for
that matter) is doing something weird, please read the file
<filename>regex.7</filename>, included in the
<filename>regex/</filename> subdirectory of the PHP distribution. It's
in manpage format, so you'll want to do something along the lines of
<command>man /usr/local/src/regex/regex.7</command> in order to read it.
</para>

<listitem>
<para>
If <parameter>limit</parameter> is set, the returned array will
contain a maximum of <parameter>limit</parameter> elements with the
last element containing the whole rest of
<parameter>string</parameter>.

&reftitle.returnvalues;
<para>
Returns an array of strings, each of which is a substring of
<parameter>string</parameter> formed by splitting it on boundaries formed
by the case insensitive regular expression <parameter>pattern</parameter>.
</para>
<para>
If there are <replaceable>n</replaceable> occurrences of
<parameter>pattern</parameter>, the returned array will contain
<literal><replaceable>n</replaceable>+1</literal> items. For example, if
there is no occurrence of <parameter>pattern</parameter>, an array with
only one element will be returned. Of course, this is also true if
<parameter>string</parameter> is empty. If an error occurs,
<function>spliti</function> returns &false;.
