如何从下至上访问和打印Json数据

Question

I have a json data like

{"Nepal":"1","India":"3","Pakistan":"2","America":"25","Bangaladesh":"23"}

Now what I want is to print and access data from last to top to print like this using PHP

Bangaladesh 23
America 25
Pakistan 2
India 3
Nepal 1

Thank you in advance..

Answer 1

you can do reverse loop like this using list.length . Code depends upon the language you are using.

for(var i=list.length-1;i>=0;i--){
 //your printing here
}

Answer 2

As Ruchan mentioned , iterating over your JSON Array object in reverse is a solution. Here is a snippet for PHP

//Decode the JSON
$array = json_decode('[{"Nepal":"1","India":"3","Pakistan":"2","America":"25","Bangaladesh":"23"}]',false); //Note: Second parameter is a boolean indicating if the resulting array should be associative or not

//Get the length of the Array
$length = count($array);

//Iterate over the array from the last index to the first (ie, length-1 to 0)
while($length) {
    echo sprintf("<p>%s</p>", $array[--$length]);
}
