Comment installer et configurer MySQLi pour PHP sur macOS ?

Setting Up MySQLi for PHP on macOS

For those facing difficulties installing MySQLi on their Mac environment, this guide provides step-by-step instructions to simplify the process.

Prerequisites:

• PHP 5 is installed and configured.
• MySQL database server is up and running.

Installation Process:

1. Install php-mysqlnd:

   Php-mysqlnd is a drop-in replacement for php-mysql, offering better performance and stability. To install it, run the following command:

   brew install php@7.4 --with-mysqlnd

   Replace "php@7.4" with the version of PHP you have installed.

2. Enable MySQLi Extension:

   After installing php-mysqlnd, you need to enable the MySQLi extension in your PHP configuration. Edit the following file based on your OS version:

   • macOS Mojave (10.14) and earlier: /etc/php.ini
   • macOS Catalina (10.15) and later: /usr/local/etc/php/7.4/php.ini

   Add or uncomment the following line:

   extension=mysqli.so  

3. Restart Apache:

   After making the changes to the php.ini file, restart Apache to apply them:

   sudo apachectl restart

Testing MySQLi:

To verify that MySQLi is installed and configured correctly, create a simple PHP script:

<?php

$mysqli = new mysqli("localhost", "username", "password", "database");

if ($mysqli->connect_errno) {
    echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
} else {
    echo "Connection to MySQL server succeeded.";
}

?>

Run the script to check if it connects to the MySQL database without any errors.
