error in zend session database for php7

Question

My application need to use database instead of file for the session management. My Application is based on Zend Framework

Answer 1

The issue is written here: https://github.com/zendframework/zf1/issues/665#issue-127528467

Since an update that returns 0 but doesn't throw an exception was still a successful query with no error

Hence the function write will return false instead of true, and PHP 7.0 requires a true result.

You can fix this by changing, in Zend/Session/SaveHandler/DbTable.php:

if ($this->update($data, $this->_getPrimary($id, self::PRIMARY_TYPE_WHERECLAUSE))) {

To:

if (is_int($this->update($data, $this->_getPrimary($id, self::PRIMARY_TYPE_WHERECLAUSE)))) {

Or you can also remove the if, turn it into an instruction, and keep the $return = true;. Because on error, the query should raise an Exception, so any update() without Exception is good.
