</span><span><span class="hljs-keyword">echo</span></span><span> </span><span><span class="hljs-string">"<p>在PHP中使用MySQL數據庫時，確保數據庫連接的字符編碼正確非常重要。字符編碼錯誤可能導致中文或其他非ASCII字符顯示異常。PHP提供了 <code>mysqli::get_charset

if ($mysqli->connect_error) {
    die("連接失敗: " . $mysqli->connect_error);
}

$charset = $mysqli->get_charset();
echo "當前數據庫連接字符集: " . $charset->charset;

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

if ($mysqli->connect_error) {
    die("連接失敗: " . $mysqli->connect_error);
}

$charset = $mysqli->get_charset();
echo "當前數據庫連接字符集: " . $charset->charset;
