removing whitespace on beginning of json data

Question

how to remove whitespace on beginning of a JSON string.

example:

{ "name" : " Test Subject" }

to

{ "name" : "Test Subject" }

the space before 'Test' to be removed

Use [`trim()`](http://www.php.net/manual/en/function.trim.php) — Xorifelse, Jan 26 '17 at 10:18
A simple 1 liner for all values, `echo json_encode(array_map('trim',json_decode($json, true)));` — Xorifelse, Jan 26 '17 at 10:27

The solution using json_decode and trim functions:

$str = '{ "name" : " Test Subject" }';
$obj = json_decode($str);
$obj->name = trim($obj->name);

$str = json_encode($obj);  // back to JSON string
var_dump($str);

The output:

string(23) "{"name":"Test Subject"}"
