Php Array conversion to string

arrays json php

I had gone through many questions regarding the array conversion but didnt gwt a solution for my problem.

I have an array as follows

array:5 [
  0 => array:1 [
    1 => "012"
  ]
  1 => array:1 [
    1 => "020"
  ]
  2 => array:1 [
    1 => "030"
  ]
  3 => array:1 [
    1 => "040"
  ]
  4 => array:1 [
    1 => "051"
  ]
]

I want to make this in the following format

["012","020","030","040","051"]

I have tried json encode and got a result as

[{"1":"012"},{"1":"020"},{"1":"030"},{"1":"040"},{"1":"051"}]

which is not i wanted.Hope someone could help.
