phpinfo缺少mbstring但在php.ini中启用

Question

与此问题类似:gd2未显示在phpinfo中,显示在php -i中

我有同样的问题mbstring.我在我的启用它php.ini(这是我整个系统中唯一的- 是的,我检查并仔细检查了它!php.ini ),但是当我打开phpinfo我的Apache时,mbstring丢失了.如果我这样做php -i,所有mbstring数据都很好地显示出来.

Apache(phpinfo.php)

Configuration File (php.ini) Path       C:\Windows
Loaded Configuration File               F:\PHP\5.4\php.ini
Scan this dir for additional .ini files (none)
Additional .ini files parsed            (none)

Apache(index.php)

Fatal error: Call to undefined function mb_get_info()

PHP CLI:

F:\Apache\httpd-2.4\htdocs> php --ini

  }

  ["strict_detection"]=>

}

这里发生了什么？臭虫apache/ phpinfo()？

Answer 1

问题是,当通过apache加载PHP时,extension_dir显然是相对于apache服务器根目录读取的.

但是,从命令行开始,它是相对于PHP根目录读取的.

因此,尽管它是相同的加载php.ini,因为我设置扩展dir ext而不是F:\PHP\5.4\ext,apache(或更确切地说:PHP)搜索它F:\Apache\2.4\ext,它没有找到明显的原因.

设置extension_dir为绝对文件夹解决了问题.现在apache和cmd都加载完全相同的配置,包括所有扩展(这正是我想要的).
