phpMyAdmin无法看到的mbstring扩展名

Question

I know there has been a lot of questions about this, but they didn't helped me to solve my problem.

I get this error when trying to access phpMyAdmin:

phpMyAdmin - Error

The mbstring extension is missing. Please check your PHP configuration.

I am running php7.0 - in php.ini located in etc/php/7.0/apache2 I have this:

extension_dir = "./"
extension_dir = "mods-available"

uncomented. I've also tried

extension_dir = "./"
extension_dir = "ext"

but it didn't work and I don't have any "ext" directory in etc/php/7.0/ so it doesnt make any sense to have it there right? Anyway I tried both options and I tried restarting apache after setting either one of them, but nothing works.

Furthermore when running

sudo apt-get install php7.0-mbstring

I get output:

php7.0-mbstring is already the newest version (7.0.4-7ubuntu2.1).
php7.0-mbstring set to manually installed.

which means it's already installed right? If I ls the directory etc/php/7.0/mods-available I can see file called mbstring.ini which I suppose is the proof it's installed. But when trying to access phpMyAdmin it still says that mbstring is missing.

Any ideas?

Your question is all over the place so let me start from scratch:

1. Run phpinfo(); from a test file and check out the extension_dir
2. Does the extension_dir point to the right place? Yes, great! No, fix it.
3. Does the extension exist in extension_dir ? Yes, nice. No, add the extension.

Also, why do you have:

extension_dir = "./"
extension_dir = "mods-available"

Did you need this instead?

extension_dir = "./mods-available"

It might be worth trying a full path like I use on my Windows machine:

extension_dir = "C:\\PHP\\x86\\7.0.2\\ext"
