Conditionals

Programming basics

A conditional statement evaluates an expression and executes instructions depending on the outcome of the evaluation. Most of the time, the evaluation is boolean (true or false).

  if player_guess == secret_number:
        print("You won in " + str(guess) + " guesses!")
       
        play_again = raw_input("Do you want to play again? ")
        if play_again == "y" or play_again == "Y" or play_again == "yes":
            guess = 0
            game = game + 1
        break
    elif player_guess < secret_number:
        print("That is a bit to low")
    elif player_guess > secret_number:
        print("That is a bit to high")

A video

This video references the C programming language and scratch, but the ideas about conditionals are excellent. In the case of conditionals, PHP and C share similar syntax (but not exact).
