convert JSON from string with array value included

As the following string, use json_decode to convert it into an array. However, after conversion, the value of TbManager:userAccesses[] is still a string.

TbManager:userAccesses[] could be converted to array by calling json_decode again for it, json_decode($json['TbManager:userAccesses[]']), but how to convert it in the first json_decode call?

$json = '{
"TbUser:username":"admin",
"TbManager:userAccesses[]":"[\"1\",\"8\"]"
}'

// converted to JSON with 'TbManager:userAccesses[]':string
// how to conver TbManager:userAccesses[] as array type
$json = json_decode($json)

As mentioned above, it's not a valid json string, but if that's what you get, here's a snippet that would convert those values to array:

$json = '{
    "TbUser:username":"admin",
    "TbManager:userAccesses[]":"[\"1\",\"8\"]"
}';

$json = json_decode($json);

array_walk_recursive($json, function (&$item, $key)
{
    if (substr($key, -2) == '[]') {
        $item = json_decode($item);  
    }
});

print_r($json);

Your $json should look like

{"TbUser:username":"admin","TbManager:userAccesses[]":[1,8]}"

In this case 'TbManager:userAccesses[]' will be array after json_decode

It's because your JSON data have bad format. The right format of your JSON data:

{"TbUser:username":"admin","TbManager:userAccesses[]":[1,8]}

in your code it will be:

$json = '{
"TbUser:username":"admin",
"TbManager:userAccesses[]":[1,8]
}';

And then:

var_dump($json);

will output:

object(stdClass)#1 (2) {
  ["TbUser:username"] => string(5) "admin"
  ["TbManager:userAccesses[]"] => array(2) {
    [0] => int(1)
    [1] => int(8)
  }
}

"TbManager:userAccesses[]":"[\"1\",\"8\"]"

Over there this is a single value "[\"1\",\"8\"]" it is not an array according to JSON syntax, hence the output you see.

Array would be when the value is like

$json = '{
"TbUser:username":"admin",
"TbManager:userAccesses":[1,8]
}';
