php 合并多维数组中相同的值

Array(
Array(
Array([stocknotifyId] => 1,[sku] => '13809_BL_37',[email] => 'huang@aaa.com'), Array([stocknotifyId] => 3,[sku] => '13809_BL_37',[email] => 'hrheve@dfwef.com'), Array([stocknotifyId] => 5,[sku] => '13809_BL_37',[email] => 'dfsfs@dfsf.com') ), Array( Array([stocknotifyId] => 2,[sku] => '13809_B_39',[email] => 'huang@aaa.com') ) Array( Array([stocknotifyId] => 4,[sku] => '13809_BL_39',[email] =>'hrheve@dfwef.com') ))
怎么写，合并后变为：
array(
[huang@aaa.com]=>array(
array( [stocknotifyId] => 1,[sku] => '13809_BL_37')
array([stocknotifyId] => 2,[sku] => '13809_B_39')
)
[hrheve@dfwef.com]=>array(
array([stocknotifyId] => 3,[sku] => '13809_BL_37')
array([stocknotifyId] => 4,[sku] => '13809_BL_39')
)
[dfsfs@dfsf.com]=>array(
array([stocknotifyId] => 5,[sku] => '13809_BL_37')
)
)

Answer 1

$arr = array(
	    array(
	        array(
				"stocknotifyId" => 1,
				"sku" => '13809_BL_37',
				"email" => 'huang@aaa.com'
			),
	        array(
				"stocknotifyId" => 3,
				"sku" => '13809_BL_37',
				"email" => 'hrheve@dfwef.com'
			),
	        array(
				"stocknotifyId" => 5,
				"sku" => '13809_BL_37',
				"email" => 'dfsfs@dfsf.com'
			)
		),
	    array(
			array(
				"stocknotifyId" => 2,
				"sku" => '13809_B_39',
				"email" => 'huang@aaa.com'
			)
		),
		array(
			array(
				"stocknotifyId" => 4,
				"sku" => '13809_BL_39',
				"email" =>'hrheve@dfwef.com'
			)
		)
	);


$re = array();

foreach($arr as $a) {
	foreach ($a as $v) {
		$tmp_v = $v;
		unset($tmp_v['email']);
		if(isset($re[$v['email']])) {
			$re[$v['email']][] = $tmp_v;
		}else{
			$re[$v['email']] = array($tmp_v);
		}
		
	}
}

print_r($re);

Answer 2

//原数组
$arr = array(
    array(
        array('stocknotifyId'=>1,'sku'=>'13809_BL_37','email'=>'huang@aaa.com'),
        array('stocknotifyId'=>3,'sku'=>'13809_BL_37','email'=>'hrheve@dfwef.com'),
        array('stocknotifyId'=>5,'sku'=>'13809_BL_37','email'=>'dfsfs@dfsf.com'),
        array(
            array('stocknotifyId'=>2,'sku'=>'13809_B_39','email'=>'huang@aaa.com')
        ),
        array(
            array('stocknotifyId'=>4,'sku'=>'13809_B_39','email'=>'hrheve@dfwef.com')
        )
    )
);

echo "<pre>";   print_r($arr);

//把$arr转换成统一格式的二维数组
$array = array();
foreach($arr as $val){
    foreach($val as $v){
        foreach($v as $vop){
            if(is_array($vop)){
                $array[$vop['stocknotifyId']] = $vop;
            }else{
                $array[$v['stocknotifyId']] = $v;
            }
        }
    }
}
ksort($array);
echo "<hr />";  print_r($array);

//转换成想要的数组
$array_res = array();
foreach($array as $val){
    $array_res[$val['email']][] = $val;
}
echo "<hr />"; print_r($array_res);


//我已经测试过了，可以转换成的

Answer 3

$s=Array( Array( Array([stocknotifyId] => 1,[sku] => '13809_BL_37',[email] => 'huang@aaa.com'), Array([stocknotifyId] => 3,[sku] => '13809_BL_37',[email] => 'hrheve@dfwef.com'), Array([stocknotifyId] => 5,[sku] => '13809_BL_37',[email] => 'dfsfs@dfsf.com') ), Array( Array([stocknotifyId] => 2,[sku] => '13809_B_39',[email] => 'huang@aaa.com') ) Array( Array([stocknotifyId] => 4,[sku] => '13809_BL_39',[email] =>'hrheve@dfwef.com') ));
// 怎么写，合并后变为：
foreach ( $s[0][0] as $t )
{
$ret['email']=array( ['stocknotifyId'] => $t['stocknotifyId'],['sku'] =>$t['sku'] );
}
