Can some PHP guru help me with this scenarios? I've been wondering around these for hours and can't find my way around it. Please...
1.
Write a function in PHP that takes three parameters (representing day, month and year) and calculates the day/month/year of the following day (for example, if the parameter is 31/10/2010, the result should be 01/11/2010). No need to take into account leap years. You cannot use any date/time specific functions, you must do it "by hand" (no built-in functions)..
2.
Write a function in PHP that takes a string and counts the number of occurrences of any given letter in it (for example, given the string "HELLO" as a parameter, there are two occurrences of "L", one of "H", one of "E", one of "O" and zero of any other character).
