How to enable php_fileinfo extension in PHP?

Question

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

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

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.

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');

But it doesn't work.

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

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>

How should you put such additionals in there?

Answer 1

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

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

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

extension=php_fileinfo.dll

Answer 2

If you are using WHM, go to Easy Apache, search fileinfo (In the search field), and enable it ( I found for php5.5 , php5.6 and php.7.0 .

And click on "Review" left tab.

Then click on provision, and done. It works for me ( I spend 3 hours trying install/enable fileinfo)

Answer 3

Create a .htaccess file where your root is and then do this

php_value extension=php_fileinfo.dll

or

php_admin_flag extension=php_fileinfo.dll

Answer 4

If you have cpanel just go to

Select PHP Version

and search for the extension

fileinfo

check it and you're good to go.

If you only want to upload images then it might help you.

$image_size_info = @getimagesize($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
}

<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 mod_suphp.c>
suPHP_ConfigPath /home/username/public_html/subfolder
</IfModule>

</IfModule>
subfolder is the laravel project where I want to serve my application.

php.ini file in my subfolder's root folder & for enable PHPFileinfo I write those code in php.ini file

extension=fileinfo.so
extension=pdo.so
extension=pdo_mysql.so
