merge arrays PHP (slice)

Question

I have an this array (i show it here as a json..):

[
{
"icon1_name":"Home Address A",
"icon2_name":"Home Address B",
"icon3_name":"Home addressC",
},
{
"icon1_name":"OfficeA",
"icon2_name":"OfficeB",
"icon3_name":"OfficeC",
}

]

I'm trying to add an array in the middle (between home address and office). This what i tried to do:

array_splice( $myArray, 1, 0, $arrayToInsert );

But i get the result with numbers:

    {
    "1":{
    "icon1_name":"OfficeA",
    "icon2_name":"OfficeB",
    "icon3_name":"OfficeC",
    "
    },
  "2":{
    "icon1_name":"PhoneA",
    "icon2_name":"PhoneB",
    "icon3_name":"PhoneC",
    "
    },
    "3":{
    "icon1_name":"FaxA",
    "icon2_name":"FaxB",
    "icon3_name":"FaxC",
    }}

How can i do this merge without getting it numbered? Thats mean, keep the original json format.

Look at the second JSON. its not the same. Its has array numbers: "1","2","3"... — user3282988

You could call array_values on the array in php which would reset the numbers back to starting with 0 and when converted to json make the outter array an array, not an object. — Jonathan Kuhn

@nl-x I could, but it really isn't ideal. The real answer should be how to not have the problem in the first place. But it does work. I just don't have the time (at work) to debug and fix it so I generally just throw up quick comments with quick fixes. — Jonathan Kuhn

The array_splice code you posted works fine with the JSON strings decoded as here:

$myArray = json_decode('[
    {
        "icon1_name":"Home Address A",
        "icon2_name":"Home Address B",
        "icon3_name":"Home addressC"
    },
    {
        "icon1_name":"OfficeA",
        "icon2_name":"OfficeB",
        "icon3_name":"OfficeC"
    }
]');

$arrayToInsert = json_decode('[
    {
        "icon1_name":"PhoneA",
        "icon2_name":"PhoneB",
        "icon3_name":"PhoneC"
    }
]');

array_splice( $myArray, 1, 0, $arrayToInsert );

print_r( json_encode($myArray) );

Output:

[
  {
    "icon1_name":"Home Address A",
    "icon2_name":"Home Address B",
    "icon3_name":"Home addressC"
  },
  {
    "icon1_name":"PhoneA",
    "icon2_name":"PhoneB",
    "icon3_name":"PhoneC"
  },
  {
    "icon1_name":"OfficeA",
    "icon2_name":"OfficeB",
    "icon3_name":"OfficeC"
  }
]

Are the JSON strings you're decoding into PHP arrays different than these?
