这一错误只影响版本号为5.2和5.3的PHP程序语言，并且只在使用X87指令集的32位英特尔cpu上出现。
The bug only seems to affect version 5.2 and 5.3 of the language, and only when they are run on Intel 32-bit CPUs that use the x87 instruction set.
这条指令本身是基于位的，因此所有类型都使用相同的底层指令。
The instruction itself is bit-based, so all types use the same underlying instruction.
为了解决这一问题，乘法指令只使用每个32位的最低有效的16 位以便结果能够放进整个 32 位寄存器内。
To combat the problem, multiplication instructions only use the least-significant 16 bits of every 32-bit value so that the result will fit in the full 32-bit register.
与使用32 位的寄存器相比，由于使用了 64位的寄存器，要执行相应的计算工作，只需使用更少的指令。
These can, by virtue of 64-bit registers, perform computations with fewer instructions than with 32-bit registers.
读者建议用巧妙的命名约定来选择样式表，但对于解决方案的最好提议来自一位同事，他提醒我使用xml - stylesheet处理指令。
Readers suggested clever naming conventions that would select a style sheet, but the best suggestion for a solution came from a colleague who reminded me of the xml-stylesheet processing instruction.
如果我们使用原来的方法，为了增加内存的容量，地址段以及指令必须比16位更长。
In order to increase the number of memory locations, the address fields and hence the instructions must be longer than 16 bits if we use the same approach.
实际上，内存地址对于任何指令格式可以使用的最大长度只有24位！
In fact, the largest length available for a memory address to any instruction format is only 24 bits!
