- cuts a substring from a string starting at "start" up to "length" characters. If start is negative - it indicates starting position from the end of the string (for example substr("test", -2, 2) will return last 2 charactes: "st"). If length is negative - it means so many characters will be omitted from the end of string (example: substr("test", 0, -2) will return string without last 2 characters: "te")
