Description

function apcu_delete(mixed $key): mixed

Removes a stored variable from the cache.

Parameters

key: A key used 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

apcu_delete(['foo', 'bar', 'baz']);

// Or use an Iterator with a regular expression.
apcu_delete(new APCUIterator('#^myprefix_#'));
