Warning: implode() [Для просмотра ссылки Войди или Зарегистрируйся]: Invalid arguments passed in /var/www/p321562/data/www/--/core2/class/functions_class.php on line 84 ($par[1]=implode("-",$dmg)

Распечатал var_dump:
string(7) "39-58.5" - $par[1]
array(2) { [0]=> int(37) [1]=> float(55.5) } - $dmg

Помогите

 

[latteo]

var_dump ($par[1]);

- нам не нужен ошибка в аргументах функции, а не в возвращаемых значениях.

var_dump ($dmg);

- надо поставить перед

 $par[1]=implode("-",$dmg);

и смотреть последний вывод перед ошибкой

Чисто ради интереса, попробуйте следующую строчку:

$par[1] = implode("-", (array)$dmg);
