从源代码编译到预编译的Windows二进制文件

Question

So in the past I've always used the pre-compiled Windows PHP binaries but then this guide caught my attention.

That brings me to this:

• Why would someone want to compile PHP from the sources when the binaries are available for them?
• Is there a performance bonus I should be aware of?
• If so, is it a significant enough amount that I should take notice?

For reference, I use PHP for mostly CLI applications mainly for bulk data processing and some website info collection.
My system specs: Windows 7 x64, 6gb RAM, Intel Q6600 (2.4gHz x 4).

Answer 1

There are three good reasons I can think of for compiling PHP rather than using a binary build on Windows:

• you need a compiled in extension or compile-time-option that does not come as standard with available binaries

• you are short of memory and need a leaner PHP executable devoid of extensions you do not use

• you want a binary compiled specifically for your processor/environment to gain the small performance boost this might achieve (possible if you have an unusual setup)

Otherwise, just stick with the binary.
