I note that php under cpanel is currently at 4.3.9, although in the whm config 4.3.11 is checked. [What is the point of these different version checkboxes?] I have a customer that wants to use YAZ. The YAZ website says that YAZ is part of php version 4. Is this true? If not, can it be easily installed? As in many such instances, the YAZ site seems to assume its readers know quite a bit already and does not have a step by step to determining whether the package is already there or how to install, except in general terms. Can anyone offer definitive answers?
