Зауваження:
Для цієї функції буде використане внутрішнє кодування символів або те, яке визначене функцією mb_regex_encoding().
Не можна використовувати
модифікатор e
, працюючи з неперевіреними вхідними даними тому,
що не відбувається автоматичного екранування (на відміну від
preg_replace()). Ігнорування цієї поради, швидше за все,
зробить програму вразливою до віддаленого виконання коду.
