## lRem, lRemove ##### *Description* Removes the first `<span class="calibre12">count</span>` occurences of the value element from the list. If count is zero, all the matching elements are removed. If count is negative, elements are removed from tail to head. IRem,IRemove函數，首先要去判斷count參數，如果count參數為0，那么所有符合刪除條件的元素都將被移除。如果count參數為整數,將從左至右刪除count個符合條件的元素，如果為負數則從右至左刪除count個符合條件的元素。 **Note**: The argument order is not the same as in the Redis documentation. This difference is kept for compatibility reasons. 函數參數的順序不一定要一致，這樣做是為了保持兼容性。 ##### *Parameters* *key* *value* *count* ##### *Return value* *LONG* the number of elements to remove *BOOL*`<span class="calibre12">FALSE</span>` if the value identified by key is not a list. ##### *Example* ``` <pre class="calibre16">$redis->lPush('key1', 'A'); $redis->lPush('key1', 'B'); $redis->lPush('key1', 'C'); $redis->lPush('key1', 'A'); $redis->lPush('key1', 'A'); $redis->lRange('key1', 0, -1); /* array('A', 'A', 'C', 'B', 'A') */ $redis->lRem('key1', 'A', 2); /* 2 */ $redis->lRange('key1', 0, -1); /* array('C', 'B', 'A') */ ``` ##
