|
Converts a string to an array. If the optional
|
|
<parameter>split_length</parameter> parameter is specified, the
|
|
returned array will be broken down into chunks with each being
|
|
<parameter>split_length</parameter> in length, otherwise each chunk
|
|
will be one character in length.
|
|
</para>
|
|
<para>
|
|
&false; is returned if <parameter>split_length</parameter> is less
|
|
than 1. If the <parameter>split_length</parameter> length exceeds the
|
|
length of <parameter>string</parameter>, the entire string is returned
|
|
as the first (and only) array element.
