将数组数组转换为json

Question

i want to convert this array as shown below

array_countries=array("20"=>array("cntryValue"=>"3","cntryLabel"=>"Egypt","value"=>"7","label"=>"Tanta"),
"21"=>array("cntryValue"=>"3","cntryLabel"=>"Egypt","value"=>"1000","label"=>"Other"),
"22"=>array("cntryValue"=>"80","cntryLabel"=>"India","value"=>"0","label"=>"All"),
"23"=>array("cntryValue"=>"80","cntryLabel"=>"India","value"=>"1","label"=>"Ahmedabad"));

into this format:

"3":{"Egypt":{"7":Tanta,"1000":"other"}},"80":{"India":{"0":"All","1":Ahmedabad}}

I am using PHP and not able to figure out how can i do this. I have used json_encode. but the results are not correct.I am using PHP as my language.

thanks in advance

Answer 1

Before converting into json, you should change the array:

$array_countries_formated = array();

foreach ($array_countries as $item)
{
    $array_countries_formated[$item['cntryValue']][$item['cntryLabel']][$item['value']] = $item['label'];
}

echo $array_countries_formated = json_encode($array_countries_formated, JSON_FORCE_OBJECT);

Result:

{"3":{"Egypt":{"7":"Tanta","1000":"Other"}},"80":{"India":{"0":"All","1":"Ahmedabad"}}}
