I need to update the version of PHP that is running on our xserver. I am told that 5.2.6 must be installed to meet a requirement for PCI compliance. Apple has 5.2.4 listed on their site as a download but not 5.2.6. I have downloaded 5.2.6 from php.net and now do not know how to install. Do I need to download anything else and how do I compile and install?
