I am having trouble compiling PHP 4.3.10 with the new Hardened PHP, if I have the Zend Optimizer (2.5.7) installed. It looks like the two may be incompatible. My question is, what do most hosts do? Do they install Zend Optimizer and not Hardened PHP or install Hardened PHP and not Zend Optimizer? Is there any other alternatives? And forgive me if I am wrong and Zend Optimizer and Hardened PHP can both be installed.
