Simple PHP Script to discover words in a phone number

This project is to create a simple search page that will compute the words that might be found in a phone numbers. I'd like to be able to enter a telephone number range. Using the touch tone key pad on a telephone, output all the letters that match the digits entered. The key pad has: 1 = 1, 2 = ABC, 3 = DEF, 4 = GHI, 5 = JKL, 6 = MNO, 7 = PQRS, 8 = TUV, 9 = WXYZ, 0 = 0 In case of 1 and 0, just use the number Example, I enter 7142285400 to 7142285420 Your script would create one line with the number to alpha conversion starting with '7' which would be 'P' then '1' which would be '1', '4' would be 'G' then '2' would be 'A' then 'A' again, '5' would equal 'J', '4' = 'G', zero = zero, zero = zero. Then move to next letter in '7' which would be 'Q' and so on until all the possible number and letter combination are done for '7142285400' then move to '7142285401' and start over.
