PHP 5.4安装后：preg_match（）：编译失败：未知选项位设置在偏移0 [英] PHP 5.4 after-install: preg_match(): Compilation failed: unknown option bit(s) set at offset 0

问题描述

我最近将我的PHP升级到版本5.4.1在我的狮子OS X 64位，我收到错误抛出在Codeigniter：

I recently upgraded my PHP to version 5.4.1 on my Lion OS X 64bit, I'm getting an error thrown in Codeigniter:

Severity: Warning

Message: preg_match(): Compilation failed: unknown option bit(s) set at offset 0

Filename: core/Utf8.php

Line Number: 44

我Googled的问题，这似乎是一个在PHP中的PCRE lib的问题，我遵循了这个教程显示安装pcre与我做的homebrew（我运行pcre 8.30），这没有解决问题。

I Googled the problem, this seems to be a problem with the PCRE lib in PHP, well I followed this tutorial which shows to install pcre with homebrew which I did (I'm running pcre 8.30) and this didn't solve the problem.

但我没有遇到一个帮助 - 是否有一个修复这个PCRE lib问题的方法？

I've tried looking around for solutions, but I haven't came across one that helped - is there a method of fixing this PCRE lib problem?

编辑：只是编辑了这个问题提醒我的安装是什么：

推荐答案

我能够得到PHP 5.4.1与PCRE版本8.12（这是包括在PHP 5.4.1版本我相信）。在所有的问题的评论中列出的所有来回，我决定编译PHP没有PCRE标志，让PHP只是使用它的默认值。通过使用默认值，它用8.12编译。

I was able to get PHP 5.4.1 working with PCRE version 8.12 (which is the version included in PHP 5.4.1 I believe). After all the back and forth listed in the question's comments, I decided to compile PHP without the PCRE flags and let PHP just use it's defaults. By using the defaults, it compiles with 8.12.

现在，后续问题是，当然，为什么会发生这种情况。我仍然希望8.30编译PHP与我提供的标志。但是，在这一点上，我只是很高兴有这个工作。

Now, a follow up questions is, of course, WHY this happens. I would still expect 8.30 to be compiled with PHP with the flags I provided. But, at this point, I am just happy to have the thing working.

以下是我的工作配置选项，如果你想尝试从你的结束。
