Calling apcu_delete() on an unexisting cached variable name doesn't generate a NOTICE (nor WARNING), making it safe to use if unsure of the state of that variable.
apcu_delete
(PECL apcu >= 4.0.0)
apcu_delete — Removes a stored variable from the cache
Parameters
-
key -
A
keyused to store the value as a string for a single key, or as an array of strings for several keys, or as an APCUIterator object.
Return Values
If key is an array, an indexed array of the keys is returned.
Otherwise true is returned on success, or false on failure.
Examples
Example #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_#'));
