An AJAX-Solr proxy written in PHP.

Just curious on the finer details on integrating this php proxy. I've come across a roadblock. Could you evaluate my stackoverflow question and give me your thoughts?

sorry,new to solr,and want to increase the Security
after download the solr-php-client and put right dir,
How to use this file?

solr don't seem to send to "start" parameter when it's equal to zero (0). Maybe we could verify that in the proxy and set the value if it's not present in the request?
