Zend Db表delete（）无法正常工作

Question

I have the following code:

$time = 60 * 60 * 24 * 3;

$usersTable = new Application_Model_Db_Users();

$where = 'active = false AND registration_time < ' . time() - $time;
$usersTable->delete($where);

But when it is run it deletes all the rows in the table, where as when I run

DELETE FROM users
WHERE active = false
AND registration_time < 1290500000

Only the ones that match the criteria are deleted. What is the problem?

Answer 1

您只需要用括号将其包装起来，这样time（）-$ time可以正确计算。

$where = 'active = false AND registration_time < ' . (time() - $time);
