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"}]

• bxN5: what do u mean json string of array? in the result you get string already
• LSG: The result is json array. json_decode is unable to decode it.
• bxN5: so the problem is you can't decode encoded string?
• LSG: yes @bxN5 that is the problem
• bxN5: your json is correct sandbox.onlinephpfunctions.com/code/…

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);

• LSG: what is the difference?
• LSG: Ok, it is fixing my problem but it is creating the order as null.
• LSG: 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);
• LSG: 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.. }
• LSG: still null using htmlentities.. the error is : PHP Warning: htmlentities() expects parameter 1 to be string, array given
