Php Mysqli Extension Is Missing Windows Drivers
Everardo Laboy
I have looked through all of the forums that I could find relevant to this question and my problem yet nothing works. I have apache2.2 with php5, phpMyAdmin, and MySQL. I have uncommented the extension, I have checked my phpinfo() and mysqli does not come up. My config directory is where it should be and it still will not load.
which states....PHP 5.3.0 and newer On Windows, for PHP versions 5.3 and newer, the mysqli extension is enabled and uses the MySQL Native Driver by default. This means you don't need to worry about configuring access to libmysql.dll.
After installation MAMP had PHP 7.3.0 enabled, PhpMyAdmin was not working (same error message, mysqli extension missing), I switched to PHP 8.1.0, restarted everything, but still no success. I checked the php.ini file in folderC:\prg\MAMP\conf\php8.1.0and the extension directory was correctly defined asextension_dir = "C:\prg\MAMP\bin\php\php8.1.0\ext\"but still I got the error
I followed below link to fix this problem. Make sure to enable following Module.
php -r 'phpinfo();' grep -i mysqli
Link : -mysqli-extension-in-ubuntu-16-04-not-working-after-upgrade-to-version-7-0-6
The above two line was not there to uncomment in php.ini, so I added at the end of the file. Also, I verified the extension file php_mysqli.dll is phyically there under c:\php\ext I am running php 5.2.10. What version of php are you using? Do you have any other suggestion that could resolved this error.
I'm trying to install Moodle 2 on Windows Server 2008 with php v. 5.3.5 and mysql v. 5.5. I got the error. However, the line you mention, ;extension=php_mysqli.dll, is not in the php.ini file. I, too, tried to add the lines:
my /etc/php.d folder doesnt contain any files. I was able to see a single php.ini file in my /usr/local/lib. and when i uncomment the extensions for mysql,mysqli and pdo_mysql, i am getting warning as
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20090626/php_mysql.dll' - /usr/local/lib/php/extensions/no-debug-non-zts-20090626/php_mysql.dll: cannot open shared object file: No such file or directory in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20090626/php_mysqli.dll' - /usr/local/lib/php/extensions/no-debug-non-zts-20090626/php_mysqli.dll: cannot open shared object file: No such file or directory in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20090626/php_pdo_mysql.dll' - /usr/local/lib/php/extensions/no-debug-non-zts-20090626/php_pdo_mysql.dll: cannot open shared object file: No such file or directory in Unknown on line 0
CentOS 5.8 and higher in a typical install of php has all the 'drivers' needed (php-mysql and php-mysqli - actually mysqli is include in the mysql driver). A CentOS server's php.ini file, BTW, shouldn't show any .dll's (that's a Windows php.ini).
I'd assume you're talking about the (very) old style MySQL functions in PHP like mysql_connect() or mysql_query(). Those functions have been deprecated for years and years, and have finally been removed in PHP 7. Use the mysqli extension or one of vendor-independent abstraction layers like PDO instead.
IMHO these packages are borked and it isn't entirely clear what provides mysqli.so, and won't work out of the box unless you enable the extension and set your path for the extension once you find it (you can use dpkg-query -L to see if mysqli.so is part of the package contents, and where it gets installed)
Recently I discovered that mysqli extension is not installed in my server Centos version 2.6. I confirm it because I change the driver of db connection from mysqli to mysql and now works fine. So, is there another way/log to determinate this problem? because the apache error_log does not say anything about it.
Loading and enabling the extension works just as in Linux - it also lies at the path found above with where php. Notepad does the trick too, but echo "extension=mysqli.so" >> /etc/php5/php.ini works too in a command line with sufficient permissions.
In short, The error is mainly due to the missing of MySQLi extension in the php.ini file. Today we saw how our Support Engineers resolve the error MySQLi extension missing on PHPMyAdmin and the different ways to enable the MySQLi extension.
PHP historically supported two libraries to connect MySQL databases. For both mysqli extension and pdo_mysql extensions, these libraries provided underlying functionality for connectivity, querying, retrieval, and processing of retrieved data.
MySQLi extension provides a mysqli_driver class to fetch the driver information (such as client version), as well as to configure certain characteristics of the driver, such as the reconnect feature only provided by the now-removed libmysql library.
It is possible that the mysqli extension is not installed at all, especially if you have just made a new PHP version available. If WordPress can not use the mysqli extension, it will try to use the old mysql one on PHP versions lower than 7.0. The key thing is having the MySQL Native Driver installed and configured for the chosen PHP version.
Install the MySQL Native Driver from your web hosting control panel or using the command line interface to have the WordPress mysqli extension enabled. For PHP 8.1, the package will be called php81-php-mysqlnd or ea-php81-php-mysqlnd.x86_64 if you are using cPanel.
Verify that the MySQL Native Driver, or mysqlnd, is installed correctly, and PHP has added .ini files for both mysqlnd and mysqli. On cPanel servers, you can find the 30-mysqli.ini and 20-mysqlnd.ini configuration files in the /opt/cpanel/ea-php81/root/etc/php.d directory, where PHP 8.1 is the PHP version used by your WordPress website. The files must contain the lines below to have the extensions loaded correctly.
Open the newly created phpinfo.php page in the browser by typing yourwebsite.com/phpinfo.php in the address bar. Replace yourwebsite.com with the actual domain name of your WordPress website. Even if no content loads due to the missing MySQL extension error, you will not have any issues opening the PHP information page.
Make sure the list of additional .ini files parsed contains the required 20-mysqlnd.ini and 30-mysqli.ini files that make sure the required PHP WordPress MySQL extension mysqli is loaded correctly and can be used by your website.
Note that the mysqli extension is compiled to use the MySQL Native Driver as the Client API Library version shows us mysqlnd. The PHP extension information shows us some additional details, including the MySQL/MariaDB port.
The PHP information page will show you whether the PHP version you use for your WordPress website has the mysqli extension installed and configured. If it is missing, install it from the PHP management interface provided by your web hosting control panel or using the command line interface.
Check the 20-mysqlnd.ini and 30-mysqli.ini referenced to see if they load the extension correctly. If you are using an outdated version of WordPress, update the installation and all plugins and themes.
The WordPress MySQL missing extension error is one of the WordPress issues related to its ability to communicate with its database. It indicates that the required PHP mysqli extension is either missing or configured incorrectly, which results in PHP being unable to send SQL queries to your WordPress database. Starting from PHP 7.0, the older mysql extension was removed in favor of mysqli, the new WordPress MySQL extension compiled to use the MySQL Native Driver.
Recent versions of Ubuntu operating systems use native MySQL drivers instead of the old PHP libraries. In this case, when the php5-mysqlnd-ms package is missing, the error Your PHP installation appears to be missing the MySQL extension which is required by WordPress may appear.
It will list all lines from PHP runtime configuration that have а mention of mysqli. Check if all settings are OK. Pay close attention of the default socket option, because it can result in a functional MySQLi extension that can't connect to the MySQL server. Consult the PHP and MySQL installation guide that you used to set up the environment to see how to correctly set up the mysql.sock.
More specifically, this problem is related to the outdated MySQL extension which was removed as of PHP 7.0. In this tutorial, we will help you fix the problem with the PHP missing MySQL extension error, and help you complete the WordPress installation successfully.
Once you install the MySQL extension for PHP, you can return back to your WordPress setup. If the installation went OK, the message about the missing MySQL extension should not be presented to you. You can now continue with your WordPress setup!
