Display output in parts in PHP
<p>I have this code:</p>

<pre><code>&lt;?php
for($i = 0; $i&lt;30; $i++)
{
    echo "$i&lt;br&gt;";          
    usleep(100000); 
}

?&gt;
</code></pre>

<p>I would like to know how make the browser display 0, then 1, then 2, ...</p>

<p>In my example, it loads for a while and then display 0-29.</p>
