Recently, I upgraded my version of PHP from 4.6 to 5.5.6. I had been using the PHP APC cache to improve performance. I’m using the Yii PHP framework and the settings I had in main.config were
‘components’=>array(
‘cache’ => array(
‘class’ => ‘system.caching.CApcCache’,
),
PHP 5.5+ now includes a built-in Zend Optimizer opcode cache so the APC cache is no longer supported. As such, my Yii main.config settings needed to change to
‘cache’ => array(
‘class’ => ‘system.caching.CDummyCache’,
),
in order to work.
