怎么把一维数组相结合
array("你好","这里","太好了","设置","帮助","他人","答案")

把元素三个组成一个

array("你好这里太好了","设置帮助他人","答案")
------解决方案--------------------

$ar = array("你好","这里","太好了","设置","帮助","他人","答案");<br />
foreach(array_chunk($ar, 3) as $v) $r[] = join('', $v);<br />
print_r($r);

Array<br />
(<br />
    [0] => 你好这里太好了<br />
    [1] => 设置帮助他人<br />
    [2] => 答案<br />
)<br />
