php version difference
<p>Any difference between php 5.3.0 and 5.2.15?</p>

<p>I am using 5.3.0 on my localhost and 5.2.15 on the remote server</p>

<p>My apps work well on the localhost and breaks on the remote server.</p>

<p>One particular error is "Only variable should be passed by reference"</p>
