This function works for you I guess:

    function json_encode4js($data) {
    $result = '{';
    $separator = '';
    $count = 0;
    foreach ($data as $key => $val) {

        $result .= $separator . $key . ':';
        if (is_array($val)){
            $result .= json_encode4js($val).(!$separator && count($data) != $count ? ",":"");
            continue;
        }
        if (is_int($val)) {
            $result .= $val;
        } elseif (is_string($val)) {
            $result .= '"' . str_replace('"', '\"', $val) . '"';
        } elseif (is_bool($val)) {
            $result .= $val ? 'true' : 'false';
        } elseif (is_null($val)) {
            $result .= 'null';
        } else {
            $result .= $val;
        }

        $separator = ', ';
        $count++;
    }

    $result .= '}';

    return $result;
}

$a = array(
"string"=>'text',
'jsobj'=>[
    "string"=>'text',
    'jsobj'=>'text2',
    "bool"=>false
    ],
"bool"=>false);

var_dump( json_encode4js($a) ); //output: string(77) "{string:"text", jsobj:{string:"text", jsobj:"text2", bool:false}, bool:false}" 

var_dump( json_encode($a));//output: string(85) "{"string":"text","jsobj":{"string":"text","jsobj":"text2","bool":false},"bool":false}"
