lInsert In the list named key, find the value of pivot, and determine whether newvalue is placed before or after pivot according to the parameters Redis::BEFORE | Redis::AFTER. If the key does not exist, it will not be inserted. If the pivot does not exist, return -1 $redis->delete('key1'); $redis->lInsert('key1', Redis::AFTER, 'A', 'X'); $redis->lPush('key1', 'A'); $redis->lPush('key1', 'B'); $redis->lPush('key1', 'C'); $redis->lInsert('key1', Redis::BEFORE, 'C', ' X'); $redis->lRange('key1', 0, -1); $redis->lInsert('key1', Redis::AFTER, 'C', 'Y'); $redis->lRange('key1', 0, -1); $redis->lInsert('key1', Redis::AFTER, 'W', 'value'); rpoplpush Return and delete the tail element of the list named srckey, and add the element to the head of the list named dstkey $redis->delete('x', 'y'); $redis->lPush('x', 'abc'); $redis->lPush('x', 'def'); $redis->lPush('y', '123'); $redis->lPush ('y', '456'); // move the last of x to the front of y. var_dump($redis->rpoplpush('x', 'y')); var_dump($redis->lRange('x', 0, -1)); var_dump($redis->lRange('y', 0, -1)); string(3) "abc" array(1) { [0]=> string(3) "def" } array(3) { [0]=> string(3) "abc" [1]=> string(3) "456" [2]=> string(3) "123" } SET operation related sAdd Add element value to the set named key. If value exists, do not write it and return false. $redis->sAdd(key, value); sRem, sRemove Delete the element value in the set named key $redis->sAdd('key1', 'set1'); $redis->sAdd('key1', 'set2'); $redis->sAdd('key1', 'set3'); $redis->sRem('key1', 'set2'); sMove Move the value element from the collection named srckey to the collection named dstkey $redis->sMove(seckey, dstkey, value); sIsMember, sContains Find whether there is a value element in the collection named key. If there is true, there will be no false. $redis->sIsMember(key, value); sCard, sSize Returns the number of elements of the set named key sPop Randomly returns and deletes an element in the set named key sRandMember Randomly returns an element in the set named key without deleting it. sInter Find intersection sInterStore Find the intersection and save the intersection to the output collection $redis->sInterStore('output', 'key1', 'key2', 'key3') sUnion Find the union $redis->sUnion('s0', 's1', 's2'); Find the union of s0,s1,s2 at the same time sUnionStore Find the union and save the union to the output collection $redis->sUnionStore('output', 'key1', 'key2', 'key3'); sDiff Find the difference set sDiffStore Find the difference set and save the difference set to the output collection sMembers, sGetMembers Returns all elements of the set named key sort Sorting, paging, etc. parameter 'by' => 'some_pattern_*', 'limit' => array(0, 1), 'get' => 'some_other_pattern_*' or an array of patterns, 'sort' => 'asc' or 'desc', 'alpha' => TRUE, 'store' => 'external-key' example $redis->delete('s'); $redis->sadd('s', 5); $redis->sadd('s', 4); $redis->sadd('s', 2); $redis->sadd('s', 1); $redis->sadd('s', 3); var_dump($redis->sort('s')); // 1,2,3,4,5 var_dump($redis->sort('s', array('sort' => 'desc'))); // 5,4,3,2,1 var_dump($redis->sort('s', array('sort' => 'desc', 'store' => 'out'))); // (int)5 string command getSet Return the value in the original key and write the value to the key $redis->set('x', '42'); $exValue = $redis->getSet('x', 'lol'); // return '42', replaces x by 'lol' $newValue = $redis->get('x')' // return 'lol' append string, the value of the string named key is followed by value. $redis->set('key', 'value1'); $redis->append('key', 'value2'); $redis->get('key');
