<simpara>
Note that <literal>elseif</literal> and <literal>else if</literal>
will only be considered exactly the same when using curly brackets
as in the above example. When using a colon to define your
<literal>if</literal>/<literal>elseif</literal> conditions, you must
separate <literal>else if</literal> into two words, or PHP will
fail with a parse error.
