Thanks! I got past the regex errors.

The reason I wanted to use the system regex library is
I wanted to compile both PHP2 and PHP3 as modules in Apache,
however, the regex libraries seem to be different in PHP2, PHP3, and
Apache. I believe it is stated a number of times how important it is to
use the same library.

Also, on the Slackware system when I compiled
(PHP2.0.1, PHP3.0.3, and Apache 1.3.1) using the PHP included regex,
the ereg_replace and other ereg commands acted funny under the PHP2.
It was probably my fault for not being careful about which regex went where,
but in any case, using the system regex eliminated that problem.

With your comment, PHP2.0.1, PHP3.0.5, and Apache 1.3.3 I went ahead and
tried it with the included regex library. It seems to be working.

I rewrote the file php2.php3 to explain what I did for
PHP2.0.1, PHP3.0.5, and Apache 1.3.3. It is at
