PHP根据数组的值分组，php array中没有自带这个函数但是很常用，今天写了出来记录一下。

$_array
=
array
(
array
(1,11,
'2016-05-18'
),
array
(2,11,
'2016-05-18'
),
array
(3,22,
'2016-05-18'
),
array
(4,22,
'2016-05-18'
),
array
(5,33,
'2016-05-19'
),
array
(6,33,
'2016-05-19'
),
array
(7,44,
'2016-05-19'
),
array
(8,44,
'2016-05-19'
),
array
(9,55,
'2016-05-20'
),
array
(10,55,
'2016-05-20'
),
);
var_dump(array_val_chunk(
$_array
));
function
array_val_chunk(
$array
){
$result
=
array
();
foreach
(
$array
as
$key
=>
$value
) {
$result
[
$value
[1].
$value
[2]][] =
$value
;
}
$ret
=
array
();
//这里把简直转成了数字的，方便同意处理
foreach
(
$result
as
$key
=>
$value
) {
array_push
(
$ret
,
$value
);
}
return
$ret
;
}

运行结果如下：
