God bless my PHP 5.3.6, there is NO such strange behavior like this:
"---
Since 5.2.1
Mersenne Twister in PHP now use new algorythm of reinitializing, developed by Richard Wagner
Same seeds not produce same chains of values.

O_\
One's more: God bless my PHP 5.3.6, there is NO such strange behavior!
Same seeds produce SAME chains of values.
And it MUST be so!
M.T. IS PSEUDO random number generator. It is useful feature.
If we need truly random we will initialize our web-applications by mt_srand(Microtemperature_of_CPU)
