Hi James,
The manual page for mysqli_stmt::execute has the following note :
When using mysqli_stmt_execute(), the
mysqli_stmt_fetch() function must be used to fetch the
data prior to performing any additional queries.
So you cannot execute the inner (sub) query without first retrieving all the
rows from the outer (main) query.
Olivier Desmares
$stmt = mysqli_prepare($db, $sql);
mysqli_stmt_execute($stmt);
mysqli_stmt_bind_result($stmt, $authkv);
while (mysqli_stmt_fetch($stmt)) {
echo "<p>MAIN: $authkv</p>";
sub($db);
}
mysqli_stmt_close($stmt);
This simple change results in the output.
MAIN: 7
