什么是设置PHP这样的整数将是64位的具体情况如何？ [英] what are the specifics of setting up PHP so that integers will be 64-bit?

问题描述

我认为PHP的总体思路能够有共同的整数64位（而不是用数学包）是使用64位硬件和64位的PHP。是否有人知道具体情况如何？例如，不会对酷睿机能够支持吗？那么32位版本的操作系统像Vista或OS X中，它们可以支持它吗？

I think the general idea of PHP being able to have common integer 64-bit (as opposed to use math packages) is to use 64-bit hardware and 64-bit PHP. Does someone know the specifics? For example, won't the Core2Duo machine be able to support it? What about the 32-bit version of OS like Vista or OS X, can they support it too?

推荐答案

只要你是在一个64位操作系统，并安装64位二进制文​​件，你是好去。

As long as you're on a 64 bit OS, and install 64 bit binaries, you're good to go.

例如，我开发框是CentOS的，我安装了PHP - * x86_64的包

e.g., my dev box is centos, and I installed php-*.x86_64 packages.

当我运行：

$ php -r 'echo PHP_INT_MAX;'

我得到：

9223372036854775807

如果64位二进制文​​件不适用于您的平台，显然有您需要记住在编译只有一个配置选项：的 - 与-LIBDIR = / lib64的

If 64 bit binaries aren't available for your platform, apparently there's only one configure option you need to remember while compiling: –with-libdir=/lib64

如果您使用的是Windows，还有丰富的资源了有重：64位PHP在Windows

If you're using windows, there are plenty of resources out there re: 64 bit PHP on Windows.
