Question

convert this: $300
to this : 300

• can’t do it with intval() or (int)
  typecasting
• if the non-numerical character is
  suffixed (300$), both works and
  returns 300
• if it is prefixed it returns 0
• the non-numerical character can be anything other than the “$”(i.e. “askldjflksdjflsd”)

Please help

EDIT : list items are not requirements, they are a list of activities and observations I have made. Sorry:(

Answer 1

$number = filter_var($number, FILTER_SANITIZE_NUMBER_INT);
