I had installed PHP from source on PPC64LE with CentOS. I had enabled the MySQLi extension during configure options. For certain portions of my web app development, the MySQL connection functions weren’t working. I learned MySQL Native driver is the recommended client library option, as it results in improved performance and gives access to features not available when using the MySQL Client Library. So I wanted to install MySQL’s Native driver as it supports all MySQL extensions (i.e., MySQL, MySQLi, and PDO_MySQL).
If you don’t have MySQLnd extension installed, then you would probably see an error something similar as shown below:
PHP Fatal error: Uncaught Error: Call to undefined method mysqli_stmt::get_result()
Install MySQLnd extension
Step 1: To install the mysqlnd, navigate to ext/mysqlnd inside the PHP source folder.
[root@terra-node-01 mysqlnd]# cd /home/user/php-7.2.30/ext/mysqlnd
Step 2: Run phpize command
[root@terra-node-01 mysqlnd]# phpize Configuring for: PHP Api Version: 20170718 Zend Module Api No: 20170718 Zend Extension Api No: 320170718
Note: If you get the error “configure: error: cannot find sources (config.m4)” during step2, follow our solution here.
Step 3: Run Configure
[root@terra-node-01 mysqlnd]# ./configure
Note: If you get an error: configure: error: Cannot find OpenSSL’s <evp.h>, follow our solution guide here.
Step 4: Run make
[root@terra-node-01 mysqlnd]# make 2>&1 | tee err.log
Step 5: Run make install
[root@terra-node-01 mysqlnd]# make install
Final Step: No need to enable these extensions manually in php.ini. Just restart the apache service
[root@terra-node-01 mysqlnd]# systemctl restart httpd
