Can PHP handle enterprise level sites as well as Java
<p>PLEASE NO FLAMING! </p>

<p>I really would love a few objective opinions about the issue. I have a project that has been strongly developed in PHP but have clients that are concerned that Java would be a better solution. I know sites such as Flickr and Digg are run on PHP, but I am concerned that PHP's lack of a running environment may destroy my project. </p>

<p>Example. PHP (that I know of) does not have an easy way to fork another process, nor is there an easy way to start a deamon to run background processes (cron jobs are a little ugly).</p>

<p>I would hate to rewrite a great piece of software, so I am in need of some solid advice. </p>
