Dynamic loading of php extensions

I’m new at php and I was trying to see if I could use the php version of ChartDirector from advsofteng.com. I’m currently using the Perl version, but now I’m studying php. When I try to run the sample scripts http://ykfp.org/php/ChartDirector/phpdemo/, it looks like they don’t run because DH has turned of dynamic loading of php extensions. A workaround described in the docs http://ykfp.org/php/ChartDirector/doc/cdphp.htm is to copy the lib into the php extension directory, and put an extension line in the php.ini file. But aren’t these inaccessible to me on DH? Is there any way that DH provides for php extensions like this?
