----------------------------------------------------------------------
On a 32-bit build {{readI64}} computes {{$hi * 4294967296 + $lo}}
([TBinaryProtocol.php:428|https://github.com/apache/thrift/blob/master/lib/php/lib/Protocol/TBinaryProtocol.php#L428]),
which exceeds {{PHP_INT_MAX}} and becomes a float — the precision loss
reported here. Fixing it exactly would mean carrying i64 as a string or
requiring bcmath/gmp throughout the PHP protocol layer. The reporter patched it
locally and said in 2018 to close it. Won't Fix.
was (Author: slachiewicz):
i64 overflow during deserialization is a 32-bit PHP platform limitation; 32-bit
PHP is long EOL and 64-bit PHP (the supported target for years) handles i64
correctly. Closing as Won't Fix.
