二维数组如何交换数据?

Jun 23, 2016 pm 01:45 PM

Array ( [0] => Array ( [sss] => 1 [abc] =>111dd ) [1] => Array ( [sss] => 2 [abc] => test ) [2] => Array ( [sss] => 3 [abc] => ) [3] => Array ( [sss] => 4 [abc] => ) [4] => Array ( [sss] => 5 [abc] =>dsafsf )  )

我想这个二维数组变成一维数组。

把里面的sss键名的值换成键名,把abc键名的值换成值。比如第一个,
Array ( [sss] => 1 [abc] => ) 变成1=>111dd

<?php$data =array(    array('sss'=>1,'abc'=>'111dd'),    array('sss'=>2,'abc'=>'test'),    array('sss'=>3,'abc'=>null),    array('sss'=>4,'abc'=>null),    array('sss'=>5,'abc'=>'dsafsf'));$ret = array();foreach($data as $item){    $ret[$item['sss']] = $item['abc'];}var_dump($ret);

这样?

array(5) {  [1]=>  string(5) "111dd"  [2]=>  string(4) "test"  [3]=>  NULL  [4]=>  NULL  [5]=>  string(6) "dsafsf"}
Copy after login

$data =array(    array('sss'=>1,'abc'=>'111dd'),    array('sss'=>2,'abc'=>'test'),    array('sss'=>3,'abc'=>22),    array('sss'=>4,'abc'=>333),    array('sss'=>5,'abc'=>'dsafsf'));foreach($data as $v){  $s=array_flip($v); $res=$res?array_merge($res,$s):$s;}var_dump($res);
Copy after login
