                            ## lTrim, listTrim


##### *Description*

Trims an existing list so that it will contain only a specified range of elements.

它將截取LIST中指定范圍內的元素組成一個新的LIST并指向KEY。簡短解說就是截取LIST。

這個可不是JS，或者PHP中清空空格的意思。

##### *Parameters*

*key* *start* *stop*

##### *Return value*

*Array*
*Bool* return `<span class="calibre12">FALSE</span>` if the key identify a non-list value.

##### *Example*

```
<pre class="calibre16">$redis->rPush('key1', 'A');
$redis->rPush('key1', 'B');
$redis->rPush('key1', 'C');
$redis->lRange('key1', 0, -1); /* array('A', 'B', 'C') */
$redis->lTrim('key1', 0, 1);
$redis->lRange('key1', 0, -1); /* array('A', 'B') */
```
