un-official miror of php.net

Hi, Is it allowed to be an un-official mirror of php.net? I mean, I want to have php.net site on my local webserver, but it's mainly for the use of our own development group (intranet), ie. not publicly available, and not to be listed in the list of php.net mirror. I'm mostly interested to have all the functionality of function reference / search, and not the whole site, eg. I don't need the download part since I can always download from the real www.php.net. Any help on how the easiest way to set this up would be appreciated Please let me know if this is OK or not. Thanks Reuben D. Budiardja
