How to get json string from an array of object

Question

Following code is giving an array with json objects. But I need json string of that array so that I can use json_decode later. How to do it?

for($i=0;$i<5;$i++)
{   foreach($allGames as $game)
    {   if($game['desc']==$sortGames[$i])
        {   $text[$i]=array('Game_name'=>$game['desc'],'GameId'=>$game['gameId'],'order'=>$goalids,'length'=>$game['length']);
            break;
        }
    }
}
$json_string=json_encode($text);

the value of $json_string is as following:

[{"Game_name":"a","GameId":"1697","order":["11022","11021","11020","11024","11023"],"length":"2.08783938975344"},{"Game_name":"b","GameId":"1800","order":["12196","12197","12194","12195","12193","12198"],"length":"1.16970835124072"}]

what do u mean json string of array? in the result you get string already — bxN5

The result is json array. json_decode is unable to decode it. — LSG

Ok, it is fixing my problem but it is creating the order as null.

I made my code as:

for($i=0;$i<5;$i++) {   foreach($allGames as $game)     {   if($game['desc']==$sortGames[$i])         {   $text[$i]=(array('Game_name'=>$game['desc'],'GameId'=>$game['gameId'],'order'=>json_decode($goalids),'length'=>$game['length']));             break;         }     } } $json_string=json_encode($text); $test=json_decode($json_string,true); var_dump($test);

and the result is

array(5) {   [0]=>   array(4) {     ["Game_name"]=>     string(1) "1"     ["GameId"]=>     string(2) "57"     ["order"]=>     NULL     ["length"]=>     string(2) "10"   }   [1]=>   .... and so on.. }
