note 101794 added to function.apc-delete

Contrary to what's documented here - apc_delete also accepts and array of keys or even an APCIterator object, making batch operations a breeze (tested in version 3.1.3p1): <?php function showCache() { $cachedKeys = new APCIterator('user', '/^MY_APC/', APC_ITER_VALUE); echo "\nkeys in cache\n-------------\n"; foreach ($cachedKeys AS $key => $value) { echo $key . "\n"; } echo "-------------\n"; } apc_add('MY_APC_TESTA_1','1'); apc_add('MY_APC_TESTA_2','2'); apc_add('MY_APC_TESTA_3','3'); apc_add('MY_APC_TESTB_4','4'); apc_add('MY_APC_TESTB_5','5'); apc_add('MY_APC_TESTB_6','6'); showCache(); /* outputs: keys in cache ------------- MY_APC_TESTB_4 MY_APC_TESTB_5 MY_APC_TESTB_6 MY_APC_TESTA_1 MY_APC_TESTA_2 MY_APC_TESTA_3 ------------- */ // delete all keys beginning with a regex match on MY_APC_TESTA $toDelete = new APCIterator('user', '/^MY_APC_TESTA/', APC_ITER_VALUE); var_dump( apc_delete($toDelete) ); // returns boolean true|false on success or failure showCache(); /* outputs: boolean true keys in cache ------------- MY_APC_TESTB_4 MY_APC_TESTB_5 MY_APC_TESTB_6 ------------- */ // explicitly delete an array of keys var_dump( apc_delete( array('MY_APC_TESTB_4','MY_APC_TESTB_5','MY_APC_NOT_EXISTS')) ); // returns an array of keys that where not found/removed from the cache showCache(); /* outputs: array 0 => string 'MY_APC_NOT_EXISTS' (length=17) keys in cache ------------- MY_APC_TESTB_6 ------------- */ // delete a single key var_dump( apc_delete('MY_APC_TESTB_6') ); // returns boolean true|false on success or failure showCache(); /* outputs: boolean true keys in cache ------------- ------------- */ ?> ---- Server IP: 92.48.74.199 Probable Submitter: 85.224.242.81 ---- Manual Page -- http://www.php.net/manual/en/function.apc-delete.php Edit -- https://master.php.net/note/edit/101794 Del: integrated -- https://master.php.net/note/delete/101794/integrated Del: useless -- https://master.php.net/note/delete/101794/useless Del: bad code -- https://master.php.net/note/delete/101794/bad+code Del: spam -- https://master.php.net/note/delete/101794/spam Del: non-english -- https://master.php.net/note/delete/101794/non-english Del: in docs -- https://master.php.net/note/delete/101794/in+docs Del: other reasons-- https://master.php.net/note/delete/101794 Reject -- https://master.php.net/note/reject/101794 Search -- https://master.php.net/manage/user-notes.php
