masking character "_" also included in database

Question

Hi,​I have a problem with data mask.​I have put the data mask format: data-inputmask:'mask': '99999999999' means user can enter their phone number in 10 or 11 characters.​But when user enter 10 character, I will received the data input mask character "_"  inside my database.​How can I exclude this character during submission.​​​

Strip it out using PHP. ​$this->data("nombor_telefon_bimbit3", preg_replace("/[^0-9]/", "", $this->data("nombor_telefon_bimbit3", "")), true);
