PHP数组到JSON数据

Question

I have arrays that looks like this:

Array ( [multi_YTnsPrfuB832.jpg] => gray [multi_hUORaTux1bI.jpg] => episode [multi_Ijtxz4U0iaq_.jpg] => fidgetq [multi_m0QWCyfVjDKh.jpg] => fidget2 )

the data inside the bracket is a URL and the value is the name. I want to encode this to be a json data to be something like this:

{ "offers":
    {
        "url":multi_YTnsPrfuB832.jpg,
        "name":"gray"
    },
    {
        "url":multi_hUORaTux1bI.jpg,
        "name":"episode"
    },
    {
        "url":multi_Ijtxz4U0iaq_.jpg,
        "name":"fidgetq"
    },
    {
        "url":multi_m0QWCyfVjDKh.jpg,
        "name":"fidget2"
    }

}

I'm fairly new to json so if someone has an idea how to implement this using php. Thanks!

To reformat your array all you need to do is iterate it and push to a new array in the format you are looking for. The json_encode function will turn an array into a JSON formatted string.

$array = /*your array*/;
$offers = [];
foreach ($array as $key => $value) {
  $offers[] = ['url' => $key, 'name' => $value,];
}
$json = json_encode(['offers' => $offers,]);
echo $json;
