php - How to make array construction?

Question

i have a problem. I have two arrays and i need to put one into other like this:

array('1'=>1,'2'=>2,'3'=>array());

Can somebody advise how to solve it?

Answer 1

如果你的第一个数组是

$first =  array('1'=>1,'2'=>2)

第二个是

$second =  array()

然后只需将其添加为

$first[] = $second

如果第二个是

$second[3] = array();

然后你想要array_merge

$first = array_merge($first,$second)

该链接左侧有各种数组函数，非常方便。
