settype() converts to bool instead of string
<p>In PHP, the settype() function as below should change the type of $myvar to a string however when I run it it displays as <em>boolean</em>.  But If i change <code>$myvar</code> to <code>$my_var</code> settype correctly changes type to string. Why is that so?</p>

<pre><code>&lt;?php
$myvar=1995;
echo "The variable is an ".gettype($myvar)."&lt;br&gt;";
$myvar=settype($myvar, "string");
echo "The variable is now a ".gettype($myvar);
?&gt;
</code></pre>

<p>Thanks &amp; Regads,
