How can the use of utf8_general_ci in database table settings impact the display of special characters in PHP?

When using utf8_general_ci in database table settings, special characters may not be displayed correctly in PHP due to the collation not being fully compatible with UTF-8 characters. To solve this issue, you can set the collation of the database table to utf8_unicode_ci, which fully supports UTF-8 characters. 

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Set the collation of the database table to utf8_unicode_ci
$sql = "ALTER TABLE table_name CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci";
$conn->query($sql);

// Close the database connection
$conn->close();
