Question

I have an array as flight_names :

           [
               "Spice Jet",
               "Go Air",
               "Air India",
               "Vistara"
           ]

i want it to change to structure

           [
               {"flight_name":"Spice Jet"},
               {"flight_name":"Go Air"},
               {"flight_name":"Air India"},
               {"flight_name":"Vistara"}
           ]

Can anyone help me , how to change to this format in LARAVEL or PHP.

Answer 1

You can use json_encode if its json output,

$arr    = ["Spice Jet", "Go Air", "Air India", "Vistara"];
$result = json_encode(array_map(function ($item) {
    return (array_combine(['flight_name'], [$item]));
}, $arr), JSON_PRETTY_PRINT);
print_r($result);die;

reference : array-combine , array-map & json-encode .

JSON_PRETTY_PRINT
Use whitespace in returned data to format it. Available as of PHP 5.4.0.

Demo

Simple foreach loop,

$arr = ["Spice Jet", "Go Air", "Air India", "Vistara"];
foreach($arr as &$v){
    $v = (array_fill_keys([$v], "flight_name"));
}
print_r(json_encode($arr));die;

Reference : array-fill-keys

Demo .

A simplified version of array_map,

$result =array_map(function($item){
    return ['flight_name' => $item];
}, $arr);

Demo .

A Simplified foreach,

foreach($arr as &$v){
    $v = ['flight_name' => $v];
}
print_r(json_encode($arr));die;

Demo .

To reverse your output,

foreach($arr as &$v){
    $v = array_flip(json_decode($v, true));
}

Output

[
    {
        "flight_name": "Spice Jet"
    },
    {
        "flight_name": "Go Air"
    },
    {
        "flight_name": "Air India"
    },
    {
        "flight_name": "Vistara"
    }
]

 $airlineArray=["Spice Jet", "Go Air", "Air India", "Vistara"];
    $finalArray=[];
    foreach($airlineArray as $key=>$value)
     {
       $arrayValue = ['flight_name' => $value];
          $finalArray[]=$arrayValue;
      }
     return $finalArray;
