Thanks Dana and thanks to rest of the people who responded.

I have debug both scripts an figured out that the program breaks, when
it's processing the values

a=5496229061, b=13

The php script returns 146638 and the perl script 524287. So also the
operation $a = ($a >> $b) yields different values in php and perl.

Or could it be, that php is smart enough to create a unsigned integer,
wheras perl does not and therefore an overflow occurs? Anyway here you
have the possibiliy of an overflow depending on how $a is handled.

Do you think >> differs in perl and php or is it an overflow problem?
