如何在PHP中启用php_fileinfo扩展名? [英] How to enable php_fileinfo extension in PHP?

问题描述

我的Laravel应用无法验证上传的图像.它返回此错误消息:

My Laravel app can't validate uploaded images. It returns this error message:

由于没有可用的猜测者，因此无法猜测MIME类型(您是否已 启用php_fileinfo扩展名?)

Unable to guess the mime type as no guessers are available (Did you enable the php_fileinfo extension?)

我知道在php.ini上启用php_fileinfo.dll/php_fileinfo.so可以解决此问题.但是我无权访问我的远程服务器的php.ini文件.

I know enabling php_fileinfo.dll/php_fileinfo.so at php.ini fixes it. But I don't have access to my remote server's php.ini file.

所以我认为还有其他方法可以启用它吗?如何?也许我可以使用PHP的ini_set()方法?我尝试像这样使用它:

So I thought is there any other way to enable it? And how? Maybe I can use PHP's ini_set() methods? I tried using it like:

ini_set('extension', 'php_fileinfo.so');

但这是行不通的.

我还读到您可以使用.htaccess文件覆盖php.ini设置.但是如何?

I also read you can override php.ini settings using .htaccess files. But how?

作为Laravel的默认设置，我的.htaccess文件为:

As Laravel's default, my .htaccess file is:

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On

    # Redirect Trailing Slashes...
    RewriteRule ^(.*)/$ /$1 [L,R=301]

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]
</IfModule>

您应该如何在其中放置这些额外物品?

How should you put such additionals in there?

推荐答案

在目录的根文件夹中创建自己的php.ini文件.

create own php.ini file in root folder of your directory.

例如，如果要在服务器上进行更改，则它应位于public.html文件夹中.

example if you are making changes on a server then it should be inside the public.html folder.

创建文件名php.ini，它将覆盖设置. 只需添加文件

create file name php.ini it will override the settings. just add in the file

extension=php_fileinfo.dll
