The updated 5.2 patch is at the same address,
http://realplain.com/php/scanner_optimizations_5_2.diff, and the original
was moved to http://realplain.com/php/scanner_optimizations_5_2-v1.diff
I've noticed a slight difference between how PHP worked without and with this patch. Previously, if you had this code:
echo "$arr[123]";
then the opcode generated would have "123" as string. Now it has it as number. Not sure if it's important, just to be aware of it.
