数据库连接-连接PHP到Interbase: &;未定义函数ibase_connect()&;

我试图将我的PHP应用程序连接到一个跨数据库，我得到以下错误

Fatal error: Call to undefined function ibase_connect() in C:'xampp'htdocs'Phase'includes'config.php on line 11

导致错误的行如下:

if(!ibase_connect($config['DBHost'] .":". $config['DBName'], $config['DBUser'], $config['DBPass'])) {
    echo "Connection Error: ". ibase_errmsg();

我对PHP世界真的很陌生，有人能告诉我应该怎么做吗?

对不起，我忘了说我使用的是windows 64位机器，如果有帮助的话

当我执行get_loaded_extensions()函数
