I want to convert an existing site to use prepared statements. This will be much easier if I can get the result of a SELECT query as an array to replace the array returned by mysqli_fetch_array. I am using PHP 5.4 with mysqlnd activated and should be able to use mysqli_stmt_get_result(stmt) to get such an array. But that function does not work and does not seem to be available at all. But all the documentation I'be read says it should be available in PHP 5.4.
$query = "SELECT col1 FROM contactinfo WHERE col2 = ? && col3 = ? && (col4 = ? || col5 = ?) ";
$stmt = mysqli_prepare($connect, $query);
mysqli_stmt_bind_param($stmt, "ssss", $var1, $var2, $var3, $var4);
mysqli_stmt_execute($stmt);
$row = mysqli_stmt_get_result(stmt);
$newvar = $row[0];
The actual query is much longer but this is the form.
If I can't use mysqli_stmt_get_result, I'll probably abandon the transition. Can someone offer advice on my next move?
