Since we are on the topic of objects with PHP, what is the best way to
free the memory being used by an object?
A lot of examples use unset($objReference). But when freeing the memory
used by a large string, it's best to assign that string's reference
variable to an empty string, ($str = "";) according to "Programming PHP"
by Tatroe and Lerdorf. I was surprised that this book didn't mention
freeing memory used by objects (or if I'm wrong, please point me to the
right page).
Here's a sample from my script I'm working on right now... is assigning
the object's reference variable to "null" redundant or not worthwhile?
// $result = a MySQL result resource
$photos_string = "";
while ($row = mysql_fetch_assoc($result)) {
$photo_obj = new PhotoItem($row['photoitem_id']);
$photos_string .= $photo_obj->display();
$photo_obj = null;
unset($photo_obj);
}
// do something with $photos_string
