wamp cannot load mysqli extension

Question

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 was running WAMP with two PHP versions 1) 5.2.9 and 2) 5.2.13.

As per site requirement i needed to change PHP version to 5.2.9 from 5.2.13. after swapping PHP version, error was "mysqli extension is missing". after debugging long time i get to know it was due to wrong "extension_dir" path in php.ini file.

So i changed its value:

Old: "extension_dir" c:/wamp/bin/php/php5.2.13/ext/

New: "extension_dir" c:/wamp/bin/php/php5.2.9/ext/

Restarted All services in wamp server, then it's fixed.

Answer 2

Had the same problem, with wamp. Try to exchange your current version of php.ini with a backup. There is one in: wamp\bin\php\php5.3.0phpForApache.txt. Worked for me.

Answer 3

I deleted the PHP in program files ad everything started working , the problem that there two installations of pHp

Answer 4

I tried many solutions, and none worked for me. I tried the following solutions:

• Restart wampserver
• Reinstall wampserver
• restart machine
• and all other solutions mentioned in this question.

However, none of these worked. Then I found that my PHPMyAdmin was not working in chrome and was working in firefox. So I tried clearing cache, restarting browser etc, but still it would not work.

Then I deleted all the files from C:\wamp\tmp and then tried again, and it works. I am not sure why it works, but here is what I think. The session was cached and not getting cleared. So as soon as I deleted all files in this directory all the sessions were deleted and hence it worked fine.

Answer 5

Just wanted to chime in on this one. Using Wamp Server 2.0, and using Zend Studio with Zend debugger for development.

I wasn't able as of yet (will get back to it at some point) to get the zend debugger working with php 5.3. So in wamp I loaded an earlier php version, 5.2.11. I was getting the same error when acessing php my admin.

What I had to do was change the php.ini file value for "extension_dir" to c:/wamp/bin/php/php5.2.11/ext/ to match the version of php I was using. After that it was all good.

First, make sure that the php.ini file is loading the mysqli extension.
If you are using WAMPServer, click on the icon in the system tray, go to PHP -> PHP Extensions and make sure it is checked. If not, go into the php.ini file and make sure that the line: extension=php_mysqli.dll is uncommented (eg, remove the ; if it exists). If that line does not exist, add it.

If this still does not work, double check that the right php.ini file is being loaded.
To do so, view your phpinfo() (Here for WAMPServer). Scroll down to the Loaded Configuration File row and see which php.ini is being loaded.Make sure it is the right file. If you're using WAMPServer, it should be(WAMP INSTALL FOLDER)\bin\apache\Apache2.2.11\bin\php.ini. By default, it isC:\wamp\bin\apache\Apache2.2.11\bin\php.ini`.

If a different php.ini file is being loaded, just rename it to something else so that PHP will try and find the file somewhere else. There should be a way to specify which on eyou want to use, but I forget exactly how to do that...

If this still doesn't work... Try messing around with phpMyAdmin's settings, or using another answer, but I'm afraid I can't help beyond this.
