PHP MySQLi mysqli_get_charset() - Character Set Information

mysqli_get_charset()

The mysqli_get_charset() function returns an object containing the properties of the current character set (charset). This helps us verify whether the database correctly supports our characters, such as č, š, and ž.

EXAMPLE

<?php
$server = "localhost";
$username = "root";
$password = "";
$database = "mysqli_database";

$connection = mysqli_connect($server, $username, $password, $database);

if (mysqli_connect_errno()) {
    printf("Connection failed: %s<br>", mysqli_connect_error());
    exit();
}

// Retrieve the object containing information about the character set
// NOTE: The mysqli_get_charset() function returns an object containing all technical details 
// about text character encoding (e.g., character set name, default collation settings, etc.). 
// Since we used var_dump(), we will see the raw structure of this object.
$charset = mysqli_get_charset($connection);
echo "<pre>";
var_dump($charset); echo "<br>";
echo "</pre>";

mysqli_close($connection);
?>

RESULT

The result will be displayed here...

Practical use: Instead of just guessing which encoding the connection uses, this function gives us a detailed insight into the server settings. Below, take a look at the object output using var_dump():

It returns an object with the properties: charset, collation, min_length, max_length, etc.

Important for ensuring the correct display of special characters.

It is used directly on the connection object.
