I often receive direct requests for support which are beyond my area of expertise and/or should be addressed to the appropriate support forum. I'm not able to research such questions. Fortunately, the open source software user community is not dependent upon my limited skills and available time, and many resources are available to address your question.
Please see http://www.apache.org/foundation/mailinglists.html for a list of ASF mailing lists in support of the many ASF projects.
Please see http://www.php.net for questions about PHP (about which I know almost nothing).
For general AIX issues, try the comp.unix.aix newsgroup.
Last but not least, don't underestimate the power of an Internet search engine such as google.
Thanks for understanding!
