Create a script that presents a word guessing game. Allow users to guess the word letter-by-letter by entering a character in a form. Start by assigning a secret word to a variable named $secret. After each guess, print the word using asterisks for each remaining letter but fill in the letters that the user guessed correctly. You need to store the user’s guess in a hidden text field name $hidden_guess. For example, if the word you want users to guess the word programming, and the user has successfully guessed the letters g and m, then store ***g**mm**g in the hidden form field $hidden_guess. Use a single script named GuessingGame.php to display and process the form. Please help me out !
