我有一个这样的数组：[
0] => Array
(
[u_id] => 1
)
[1] => Array
(
[u_fname] => Aristo
)
[2] => Array
(
[u_id] => 6
)
[3] => Array
(
[u_fname] => Anil
)
但是，我希望我的数组是这样的形式：
array(array[0]=>
array([uid]=>0,['u_name']=>Aristo)),
array([1]=>[uid]=>1,['u_name']=>Anil)
试试这个：
<?php
//this is your array in question
$single = array(
array(
'u_id' => 1
),
array(
'u_fname' => Aristo
),
array(
'u_id' => 6
),
array(
'u_fname' => Anil
)
);
print_r($single);
$multi = array_map(function($item) {
$return = array();
array_walk_recursive($item, function($value, $index) use (&$return) {
$return[$index] = $value; //flatten array, but keeping index
});
return $return;
}, array_chunk($single, 2)); //split array into sections containing two elements
print_r($multi);
输出：
Array
(
[0] => Array
(
[u_id] => 1
)
[1] => Array
(
[u_fname] => Aristo
)
[2] => Array
(
[u_id] => 6
)
[3] => Array
(
[u_fname] => Anil
)
)
Array
(
[0] => Array
(
[u_id] => 1
[u_fname] => Aristo
)
[1] => Array
(
[u_id] => 6
[u_fname] => Anil
)
)
