Örnek 1 A apcu_delete() example
<?php
$bar = 'BAR';
apcu_store('foo', $bar);
apcu_delete('foo');
// this is obviously useless in this form
// Alternatively delete multiple keys.
apcu_delete(['foo', 'bar', 'baz']);
// Or use an Iterator with a regular expression.
apcu_delete(new APCUIterator('#^myprefix_#'));
