无法解析看起来完全相同的两个json字符串之一

Question

I used JSON.stringify to convert a JSON object to string, stored it in a database and retrieved it. When I am trying to decode it into json using json_decode(), it is returning NULL(I used var_dump() to verify it).

{"profilediv":" klsadnlksa ","profilediv2":" sankldnlkas ","profilediv3":" nsjakdnsjka "}

{"profilediv":"nsjakdnsjka","profilediv2":"sankldnlkas","profilediv3":"klsadnlksa"}

I am able to parse the second string, but not the first one. Here the entire code.

  <?php
$x = '{"profilediv":"

klsadnlksa

","profilediv2":"

sankldnlkas

","profilediv3":"

nsjakdnsjka

"}';
$x = trim($x);
$y = json_decode($x,true);
var_dump($y);
$json = '{"profilediv":"nsjakdnsjka","profilediv2":"sankldnlkas","profilediv3":"klsadnlksa"}';
var_dump(json_decode($json));
?>

And here is the output

NULL object(stdClass)#1 (3) { ["profilediv"]=> string(11) "nsjakdnsjka" ["profilediv2"]=> string(11) "sankldnlkas" ["profilediv3"]=> string(10) "klsadnlksa" }

I am able to parse $json but not $x. Any help is appreciated.Thanks in advance.

Add this to remove new-lines

$x = str_replace("
",'',$x);
$y = json_decode($x,true);

Will be var_dumped as:

Array
(
    [profilediv] => klsadnlksa
    [profilediv2] => sankldnlkas
    [profilediv3] => nsjakdnsjka
)

trim — Strip whitespace (or other characters) from the beginning and end of a string
