PHP invoking another script but through http (isolating them)
<p>Let's see if I make myself clear. I have an old set of scripts that run well on PHP4 and better don't thouch em. I have to integrate a new functionality implemented on PHP5, I need just to invoke a script on the new app from the old one.</p>

<p>To not have to touch the old stuff I think to somehow "kin of remotely" invoke the new one, need only to pass the $_REQUEST[] data. I can not include it as that would require migrating to another PHP version (and some name clashing). I don't need any output from the new one.</p>

<p>What would be the cleaner way to "call" that script passing parameters, fopen("http://theserver.com/thescript.php"....) and then passing all the necessary headers to pass the parameters? or there's somethign more direct?</p>

<p>Thanks!</p>
