Why does PHP sometimes return a blank page without an error?
<p>I use PHP for programming contests (bad choice, I know. But it's the only language I'm good at). Often, when I create a very large variable, PHP returns a blank page. No errors are generated.</p>

<p>For example, if I have a script like this:</p>

<pre><code>&lt;?php
echo 'test';

$var=array();
for($i=0;$i&lt;9999999999;$i++){
  $var[]=$i*9999999999;
}
</code></pre>

<p>No output would be outputted; not even the "test".</p>

<p>Is there a way to prevent this?</p>

<p>P.S. The script usually terminates quickly, in about 2-3 seconds. Which leads me to think that PHP is terminating the script without reaching the end.</p>
