Does php.ini controls this syntax behavior?
<p>I have a method <code>bar()</code> that returns an array. When I do the following assignment:</p>

<pre><code>$foo = bar()[0];
</code></pre>

<p>I get a syntax error in one of two servers with the identical OS/apache/php version:</p>

<pre><code>PHP Parse error:  syntax error, unexpected '[' in ...
</code></pre>

<p>PHP version on both servers: 5.4.10</p>
