更新详情

HHVM 4.50 is released! This release marks the end of support for 4.44;
HHVM 4.45–4.49 remain supported, as do the 4.8 and 4.32 LTS releases.Additionally, we are no longer building binary packages for MacOS High Sierra
for any version of HHVM, as High Sierra is no longer offered by our build
infrastructure provider.Highlights added the hhvm.hack_arr_is_shape_tuple_notices INI setting, which raises
a notice on $dict is shape() and $vec is tuple(); these are currently
always false, but may be true in the future, so are unsafe to depend on.
HH\BuiltinEnum is now covariant.
Improve hackfmt’s range formatting when suppressions outside the requested
range affect code within the requested range.Breaking Changes magic methods (__get, __set, __isset, __unset) have been removed from
the typechecker definitions of builtins, such as the XMLReader, Imagick,
DateTime, and SimpleXML extensions.
it is now a type error to use argument unpacking when invoking a default
constructor. It was already an error to make a variadic call to functions that
take exactly zero arguments, and as default constructors always have exactly
zero arguments, this makes the behavior consistent. This was previously
a runtime error.Future Changes array() literals will be removed; the hhvm.hack.lang.disable_array=true
INI setting can be used to enable a runtime fatal when they are used, in
addition to the preexisting disallow_array_literal=true .hhconfig option.
The magic methods on builtins that were removed from the typechecker in this
release will be removed from the runtime in a future release.

软件描述

HHVM (HipHop Virtual Machine)会将PHP代码转换成高级别的字节码(通常称为中间语言)。然后在运行时通过即时(JIT)编译器将这些字节码转换为x64的机器码
