How to print boolean as string in php? : <p>I have a boolean in php. When I do something like :</p>

<pre><code>  sprintf('isTrue=%s', isTrue)
    Here isTrue is boolean
</code></pre>

<p>I get something like <code>isTrue=1</code> or <code>isTrue=</code>. Is there simple way to get <code>isTrue=True</code> or <code>isTrue=False</code></p>
