apcu_delete Removes a stored variable from the cache


apcu_delete(mixed $key): mixed

Removes a stored variable from the cache.

Bağımsız Değişkenler


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.

Dönen Değerler

If key is an array, an indexed array of the keys is returned. Otherwise true is returned on success, or false on failure.


Örnek 1 A apcu_delete() example

= 'BAR';
apcu_store('foo', $bar);
// 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_#'));

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.
