关于数组合并的问题
原数组:


$args1 = Array(
'0' =&gt; array(
'0' =&gt; 'a',
'1' =&gt; array(
'0' =&gt; array ( 'col1' =&gt; 'A1', 'col2' =&gt; 0 )
)
),
'1' =&gt; array(
'0' =&gt; 'b',
'1' =&gt; array(
'0' =&gt; array ( 'col1' =&gt; 'B1', 'col2' =&gt; 1 )
)
)
);
$args2 = Array(
'0' =&gt; array(
'0' =&gt; 'a',
'1' =&gt; array(
'0' =&gt; Array ( 'col1' =&gt; 'A2', 'col2' =&gt; 0 ), 
'1' =&gt; Array ( 'col1' =&gt; 'A3', 'col2' =&gt; 0 ) 
)
)
);

目标数组：


Array(
'0' =&gt; array(
'0' =&gt; 'a',
'1' =&gt; array(
'0' =&gt; array ( 'col1' =&gt; 'A1', 'col2' =&gt; 0 ),
                                        '1' =&gt; Array ( 'col1' =&gt; 'A2', 'col2' =&gt; 0 ), 
'2' =&gt; Array ( 'col1' =&gt; 'A3', 'col2' =&gt; 0 ) 
)
),
'1' =&gt; array(
'0' =&gt; 'b',
'1' =&gt; array(
'0' =&gt; array ( 'col1' =&gt; 'B1', 'col2' =&gt; 1 )
)
)
);

[解决办法]

$res = array();
foreach($args1 as $item) $res[$item[0]] = $item;
foreach($args2 as $item) $res[$item[0]][1] = array_merge($res[$item[0]][1], $item[1]);

print_r(array_values($res));

Array
(
[0] => Array
(
[0] => a
[1] => Array
(
[0] => Array
(
[col1] => A1
[col2] => 0
)

[1] => Array
(

[col1] => A2
[col2] => 0
)

[2] => Array
(
[col1] => A3
[col2] => 0
)

)

)

[1] => Array
(
[0] => b
[1] => Array
(
[0] => Array
(
[col1] => B1
[col2] => 1
)

)

)

)
