How to enable php_fileinfo extension in PHP?
提问by doncadavona
My Laravel app can't validate uploaded images. It returns this error message:
我的 Laravel 应用无法验证上传的图片。它返回此错误消息：
Unable to guess the mime type as no guessers are available (Did you enable the php_fileinfo extension?)
无法猜测 mime 类型，因为没有可用的猜测器（您是否启用了 php_fileinfo 扩展？）
I know enabling php_fileinfo.dll/php_fileinfo.so at php.ini fixes it. But I don't have access to my remoteserver's php.ini file.
我知道在 php.ini 启用 php_fileinfo.dll/php_fileinfo.so 可以修复它。但我无权访问远程服务器的 php.ini 文件。
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:
所以我想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？我尝试使用它，例如：
ini_set('extension', 'php_fileinfo.so');
But it doesn't work.
但它不起作用。
I also read you can override php.ini settings using .htaccess files. But how?
我还读到您可以使用 .htaccess 文件覆盖 php.ini 设置。但是如何？
As Laravel's default, my .htaccess file is:
作为 Laravel 的默认值，我的 .htaccess 文件是：
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
RewriteEngine On
# Redirect Trailing Slashes...
RewriteRule ^(.*)/$ / [L,R=301]
# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
How should you put such additionals in there?
你应该如何把这些额外的东西放在那里？

create own php.inifile in root folder of your directory.
php.ini在目录的根文件夹中创建自己的文件。
example if you are making changes on a server then it should be inside the public.html folder.
例如，如果您在服务器上进行更改，那么它应该位于 public.html 文件夹中。
create file name php.ini it will override the settings. just add in the file
创建文件名 php.ini 它将覆盖设置。只需在文件中添加
extension=php_fileinfo.dll

If you only want to upload images then it might help you.
如果您只想上传图片，那么它可能对您有所帮助。
$image_size_info = @getimagesize($filename); //surpress errors(@) if not image
if( empty($image_size_info) ) $mime_type = "";
else $mime_type = @image_type_to_mime_type( $image_size_info[2] );
//safety for all cases:
if( empty($mime_type) ) $mime_type = "";
if( strpos($mime_type, "image/") === false )
{
//not an Image !
}
else
{
//proceed file upload
}
