Convert array to JSON in proper format - php

Question

I'm trying to convert my array to JSON.
My JSON is stored in the database and will later be decoded for permission checking.
Example,
How I want it to be stored in the database:
{ "admin": 1,
"create_posts": 1,
"edit_posts": 1,
"delete_posts": 1 }
How it is being stored now:
{"0":"\"admin\": 1",
"1":"\"create_posts\": 1",
"2":"\"edit_posts\": 1",
"3":"\"delete_posts\": 1"}
My code:
$check_list = $_POST['check_list'];
$list = array();
foreach($check_list as $key) {
$key = '"' . $key .= '": 1';
array_push($list, $key);
}
$json = json_encode($list, JSON_FORCE_OBJECT);
How would I make it so that it stores in the database like I want it to be?
I'm quite new to this, so any hints instead of direct answers is also much appreciated!
UPDATE:
JSON decode and validation:
$permis = json_decode($permissions->permissions, true);
echo ($permis['admin'] == true) ? 'allowed' : 'disallowed';

Answer 1

$arr = [ 'a', 'b', 'c' ];
echo json_encode(
array_combine(
$arr,
array_fill(0, count($arr), 1)
),
JSON_PRETTY_PRINT
);
Output:
{
"a": 1,
"b": 1,
"c": 1
}

Answer 2

I'm assuming the incoming data looks like this.
$incoming_data = "admin=1&create_posts=1&edit_posts=1&delete_posts=1";
$pairs = parse_str($incoming_data);
so we take the incoming pairs and use the $key as the array index so you don't get the extra array element index.
$permissions = array();
foreach($pairs as $key => $value){
$permissions[$key] = $value;
}
then we encode the new array to get the JSON you're looking for.
print json_encode($permissions);
will print out JSON like this:
{
"admin":"1",
"create_posts":"1",
"edit_posts":"1",
"delete_posts":"1"
}
The main thing to change in your code is this.
foreach($check_list as $key) {
$list[$key] = 1;
}
