php 添加二维数组元素,PHP在二维数组里增加元素(保留健名或不保留健名)
//原数组
$data = array(
array( 'id' => '8', 'name' => '未分组' , 'count' => 208),
array( 'id' => '8', 'name' => '未分组' , 'count' => 208),
array( 'id' => '8', 'name' => '未分组' , 'count' => 208),
array( 'id' => '8', 'name' => '未分组' , 'count' => 208),
);
//增加3个指定元素；
$aa= '8777';
$bb = 'dddd';
$cc = 'ewewew';
//1、在二维数组里增加元素保留原有的健名
array_walk($data, function(&$v, $k, $p) { $v = array_merge($v, $p); }, array($aa, $bb, $cc));
print_r($data);
Array
(
[0] => Array
(
[id] => 8
[name] => 未分组
[count] => 208
[0] => 8777
[1] => dddd
[2] => ewewew
)
[1] => Array
(
[id] => 8
[name] => 未分组
[count] => 208
[0] => 8777

[2] => ewewew
)
[2] => Array
(
[id] => 8
[name] => 未分组
[count] => 208
[0] => 8777
[1] => dddd

[3] => Array
(
[id] => 8
[name] => 未分组
[count] => 208
[0] => 8777

)
);
//2、在二维数组里增加元素去掉原有的健名
array_walk($data, function(&$v,$k,$p) { $v = array_merge(array_values($v),$p); },array($aa,$bb,$cc));
print_r($data);
