WAMP installed fine, no problems, BUT...

When going to phpMyAdmin, I get the error from phpMyAdmin as follows:

Cannot load mysqli extension. Please c         


        

Answer 1

I got this problem for a long time.
Tried all I've read on forums and this finally worked for me:
Open your php.ini (I assume you've got the good one that is loaded...) and find this line mysqli.default_port = 3306
change for
mysqli.default_port = 80
Restart all services
Go to localhost/phpmyadmin -> won't work
Reopen the php.ini file and retype this
mysqli.default_port = 3306
Restart all services
Worked for me.

Answer 2

I have just installed WampServer, and faced same problem. I have found solution, that works for me, it is ridiculously simple.

1. Disable PHP extension php_mysqli.
2. Restart WampServer, visit local phpmyadmin.
3. Enable php_mysqli back.
4. Repeat step 2.

After few page refreshes, remaining errors plates (about MySQL and sqli) had gone.

Answer 3

For me worked this, after searching all logs/internet/every non-normal things. You have to register dl by:

Through application:

WAMP -> PHP settings -> enable dl

or

# php.ini #

; Whether or not to enable the dl() function.  The dl() function does NOT work
; properly in multithreaded servers, such as IIS or Zeus, and is automatically
; disabled on them.
; http://php.net/enable-dl
enable_dl = On

Answer 4

i tried hard by installing the wamp again and again, by checking the php.ini file, by restarting the machine, by replacing the index.php file,

but none works. then i go to the wamp/temp and deleted all files and it works fine now.

Answer 5

in wampserver go to php.ini. open the file and uncomment extension=msql.dll by removing semicolon(;) for respective operating sytem.

Answer 6

I had this problem and spent 2 hours trying all the solutions online, none worked.

Tried this, and it woked:

Change

mysql.default_host =

to

mysql.default_host = localhost

and restart WAMP. pay attention if you are using mysqli or not.
