Answer 1

I created a class to format json with php without quotes on the keys here is it

class JsonFormatter
{
static $result = '';
static $separator = '';

public static function iterateArray($data) : string
{
    static::$result .= '[';
    static::$separator = '';
    foreach ($data as $key => $val) {
        if (is_int($val)) {

        } elseif (is_string($val)) {
            static::$result .= '"' . str_replace('"', '\"', $val) . '"';
        } elseif (is_bool($val)) {
            static::$result .= $val ? 'true' : 'false';
        } elseif (is_object($val)) {
            static::iterateObject($val);
            static::$result .= ', ';
        } elseif (is_array($val)) {
            static::iterateArray($val);
            static::$result .= ', ';
        } else {
            static::$result .= $val;
        }
        if (!is_int($val)) {
            static::$separator = ', ';
        }
    }

    static::$result .= ']';
    return static::$result;
}

public static function iterate($data)
{
    if (is_array($data)) {
        static::iterateArray($data);
    } elseif (is_object($data)) {
        static::iterateObject($data);
    }
    return static::$result;
}

public static function iterateObject($data)
{
    static::$result .= '{';
    static::$separator = '';
    foreach ($data as $key => $val) {

        static::$result .= static::$separator . $key . ':';

        if (is_int($val)) {
            static::$result .= $val;
        } elseif (is_string($val)) {
            static::$result .= '"' . str_replace('"', '\"', $val) . '"';
        } elseif (is_bool($val)) {
            static::$result .= $val ? 'true' : 'false';
        } elseif (is_object($val)) {
            static::iterate($val, true);
            static::$result .= ', ';
        } elseif (is_array($val)) {
            static::iterateArray($val, true);
            static::$result .= ', ';
        } else {
            static::$result .= $val;
        }
        static::$separator = ', ';
    }
    static::$result .= '}';
    return static::$result;
}

}

you can now call

$jsonWithoutKeyQuotes  = JsonFormatter::iterate($data);
