Question

I have a table and php script. I want to fetch all datas (with PDOStatement->fetchAll() expression). I can do it. But there is a JSON column among my columns in the table. When I fetch this, the JSON data fetching as text format. I want to this JSON data be an array.

For example:

I can fetch that;

Array
(
[ID] => 1
[name] => Example
[json] => [1,2,3]
)

But I want to this;

Array
(
[ID] => 1
[name] => Example
[json] => Array
(
[0] => 1
[1] => 2
[2] => 3
)
)

So I need the parse the JSON data when fetch the SQL query. Thanks.

Best answer

[json] => [1,2,3] - this is array

and this also

[json] => Array
(
[0] => 1
[1] => 2
[2] => 3
)
)

If you use Mysql write that Json in Mysql

When You fetch this in php You can

$res = your query to DB
foreach($res as &$r)
{
  $r = json_decode($r['json']) 
}

Example

$a[]['json'] = '{"name":"John1","age":31,"city":"New York"}';
$a[]['json'] = '{"name":"John2","age":31,"city":"New York"}';


foreach($a as &$r) 
{
    $r = json_decode($r['json']);
}
var_dump($a);
