Description: Memory leaks attributable to OO PHP

The short version scored 7680 hits over 2 min, whereas the Object Oriented version 
scored around 1700 hits over 2 min running 4 threads.

Both scripts do the same thing, query to database, with same result, but the OO 
version seems to be 5 times slower, so I am classifying this bug as a performance

I wrote two scripts to compare the difference in performance between simple script and 
one written in OO with classes and required libraries. Both scripts accessed the SQL 
database using ADODB connection. I used Microsoft Web Application Stress Tool, which 
seems to be very useful.
The "simple" version yielded better performance in less CPU usage (and no memory 
leaking), whereas the OO version maxed out the CPU usage 100%, as well as slowly but 
surely leaking memory.
I tried using the unset() function in several places in the code, but this did not 
help much, as the script was still leaking memory during the tests.

Using unset() to unset the COM object helped a lot, as PHP did not seem able to free 
the memory by itself.
