mysqli_stmt::store_result
storing this object in ANY kind will result in storing an empty object... if you try to serialize it dump it or do anything with it you will end up with a empty object.
you have to pull all data out f the object and then store the data... no other way.

Generally, it appears Mysqli OO vs Procedural style has no significant difference in speed, at least with the more generally used functions and methods (connect, close, query, free, etc).
With the fetch_* family of functions and methods dealing with result rows, however, Procedural wins out. Averaging over a hundred or so tests with a result set of 180,000 records, and using mysqli_fetch_*() functions vs. their mysqli_result::fetch_*() counterpart object methods to read and iterate over all records, all of the mysqli_fetch_*() functions win by ~0.1 seconds less.
This is interesting considering we're dealing with the same result object in both styles.
This was using Vistax64, PHP5.3.2, Mysql 5.1.45, using a bit of this code:
<?php
// procedural - takes 0.1 seconds less than OO here
$stopwatch = microtime(true);
while($row = mysqli_fetch_assoc($result)){
++$z;
}
echo microtime(true) - $stopwatch;
// OO
$stopwatch = microtime(true);
while($row = $result->fetch_assoc()){
++$z;
}
echo microtime(true) - $stopwatch;
?>

Extending the MySQLi_Result
<?php
class Database_MySQLi extends MySQLi
{
public function query($query)
{
$this->real_query($query);
return new Database_MySQLi_Result($this);
}
}
class Database_MySQLi_Result extends MySQLi_Result
{
public function fetch()
{
return $this->fetch_assoc();
}
public function fetchAll()
{
$rows = array();
while($row = $this->fetch())
{
$rows[] = $row;
}
return $rows;
}
}
?>
