Description:
------------
We are using php4.4.7 with apache 2 on linux 2.x having mysql as database.
Recently upgraded mysql to 4.1.21 from 4.0.27 & since then started getting segmentation fault, & on the web site page cant be displayed.

we tried to downgrade to mysql 4.0.27 again but the mysql client API doesnot change. After downgrading When we are checking the version from prompt with mysqladmin then its showing 4.0. but when we check it on phpinfo.php then it gives client api of 4.1.21.

Again we upgraded to mysql enterprise 5.0.46 & facing the same problem.

The steps we follow is,

Install mysql (from binary, copying the files to /usr/local/mysql) & then configure & make, make install for php. 

Any quick assistance on this issue is greatly appreciated.

Expected result:
----------------
Our expectation is that
either php 4.4.7 should work with mysql 5
or we should go back to mysql 4.0.27 which currently not happening as we see on phpinfo.php.

We have upgrade to mysql 5.0.46 & configured php 4.4.7 with mysql.
In the phpinfo.php page, where we can see all the software & configuration related information, the mysql client API version is shown as 5.0.46.
Now we downgraded mysql to 4.1.21 & configured php with mysql. But the mysql client API version doesnt change. It remains on 5.0.46.

Is there anything different that I need to do while configuring php?

Can the mysql client API be downgraded atall?

This means that you've built PHP with new MySQL headers from 5.0.46.
