php5 sqlite3 result and free

Question

I am using php5 and now sqite3.

I don't know how free result. The following code

$query = "SELECT ...;";
$result = $GLOBALS['sqlite']->query($query);
$row = $result->fetchArray(SQLITE3_ASSOC);
$result->free();

ends with Error UNDEFINED METHOD . What am I doing wrong?

And finally, I want to ask if it is faster to call free() or never free the result?

Answer 1

正确的答案是$result->finalize();
