Wrapping a custom php extension

I'm trying to wrap a custom php extension from a C library, now I have an Initializer function which initiate a specific custom connection and seems to be expensive one and i should not run it each time I call the function.

Let's suppose that I have the following in the ZEND wrapper,

PHP_FUNCTION(get_data){
    conn = conn_init();
    data = getdata(conn);
    return data;
}

conn_init() is an expensive call here, where should I put that function?

and can I ask users to call conn_init() from PHP and how?

Looks like you should wrap conn as a resource.

Then a script using your extension could look like

$conn = YOUREXT_connect($cparams);
$data[1] = YOUREXT_getdata($conn, $params[1]);
$data[2] = YOUREXT_getdata($conn, $params[2]);
$data[3] = YOUREXT_getdata($conn, $params[3]);
