如何在php中加入两个数组

Question

I have two arrays called $array1 and $array2

and var_dump gives

array (size=1)
  0 => 
    array (size=5)
      'userid' => string '8' (length=1)
      'useremail' => string 'venkat@gmail' (length=12)
      'username' => string 'venkatesh' (length=9)
      'password' => string '1111' (length=4)
      'Name' => string 'venkatesh' (length=9)

array (size=1)
  'modenames' => 
    array (size=3)
      0 => string 'group 4' (length=7)
      1 => string 'group 4' (length=7)
      2 => string 'group 4' (length=7)

now i need to make a json something like this

  {
    "userid":"8",
    "useremail":"venkat@gmail",
    "username":"venkatesh",
    "password":"1111",
    "Name":"venkatesh",
    "modenames":{"group 4","group 4","group 4"}
    }

i have used array_merge() and $array1+$array2 both gives a json not in above format.. help me out.

In this case you need to,

$t = [
    0 => [
        'userid' => '8',
        'useremail' => 'venkat@gmail',
        'username' => 'venkatesh',
        'password' => '1111',
        'Name' => 'venkatesh'
    ]
];

$s = [
    'modenames' => [
        0 => 'group 4',
        1 => 'group 4',
        2 => 'group 4',
    ]
];

$t = $t[0] + $s;
// or
array_merge($t[0], $s);
