php新手，求教各位大神，关于二维数组按照一定条件合并的问题

[kangaa]

有这样类型的三个二维数组：
$arr = Array
(
"0" => Array(
"hzlx" => '买断',
"yfs" => '400',

),

"1" => Array(
"hzlx" => '关店',
"yfs" => '3',

),

"2" => Array(
"hzlx" => '关门',
"yfs" => '5',

),

"3" => Array(
"hzlx" => '待开发-未开门',
"yfs" => '1',

),

"4" => Array(
"hzlx" => '待开发-未谈',
"yfs" => '1',

),

"5" => Array(
"yfs" => '889',
"hzlx" => '独家',
),
"6" => Array(
"hzlx" => '独家-配货',
"yfs" => '2',

),
);
$arr1 = Array(
"0" => Array(
"hzlx" => '买断',
"shul" => '48555',
"cb" => '59633.90000000002',
"glcb" => '0',

),

"1" => Array(
"hzlx" => '独家',
"shul" => '82980',
"cb" => '97979.40000000002',
"glcb" => '0',

),

"2" => Array(
"hzlx" => '独家-配货',
"shul" => '17',
"cb" => '7.85',
"glcb" => '0',

),
);
$arr2 = Array(
"0" => Array(
"hzlx" => '买断',
"fkje" => '450',
"lzs" => '10',

),

"1" => Array(
"hzlx" => '独家',
"fkje" => '450',
"lzs" => '9',

),
);
按照相同的hzlx进行合并成这样的一个二维数组：
$arr3 = Array
(
[0] => Array(
[hzlx] => 买断,
[yfs] => 400,
[lzs] => 10,
[fkje] => 450,
[shul] => 48555,
[cb] => 59633.90000000002,
[glcb] => 0,
),

[1] => Array
(
[hzlx] => 关店,
[yfs] => '',
[lzs] => '',
[fkje] =>'',
[shul] => '',
[cb] => '',
[glcb] => '',
),

[2] => Array
(
[hzlx] => 关门,
[yfs] => '',
[lzs] => '',
[fkje] => '',
[shul] => '',
[cb] => '',
[glcb] => '',
),

[3] => Array
(
[hzlx] => 待开发-未开门,
[yfs] => '',
[lzs] => '',
[fkje] => '',
[shul] => '',
[cb] => '',
[glcb] => '',
),

[4] => Array
(
[hzlx] => 待开发-未谈,
[yfs] => '',
[lzs] => '',
[fkje] => '',
[shul] => '',
[cb] => '',
[glcb] => '',
),

[5] => Array
(
[hzlx] => 独家,
[yfs] => '889',
"fkje" => '450',
"lzs" => '9',
"shul" => '82980',
"cb" => '97979.40000000002',
"glcb" => '0',
),


[6] => Array
(
[hzlx] => 独家-配货,
[yfs] => '2',
[lzs] =>'',
[fkje] =>'',
"shul" => '17',
"cb" => '7.85',
"glcb" => '0',
),
);
以第一个数组为基准进行合并，没有的为空或0
