  1. I just started Beginners PHP course, when i use echo to display the result, it shows nothing. When i open beginners course file with forms it doesnt display echo on the screen as well. Can someone help me solve this problem?
  2. JavaScript Loops

    I understand that but if we start with 5 then print on the screen current number, and then substract 1 from it, and repeat cycle, why isnt order 5,4,3,2,1 there? instead it goes from 1.
  3. JavaScript Loops

    I have two question about JS loops. Its about while loops. 1)if we type this line of code target.innerHTML = "LoopCount: " + loopCount + "<br>" + target.innerHTML; why does it write from lowest number to highest like this? LoopCount: 1 LoopCount: 2 LoopCount: 3 LoopCount: 4 LoopCount: 5 The function tells that starting loop is 5,we are targeting empty paragraph with id "target", then writting into it some text and saying that we want to see current loop number, which is 5 at the beginning , then we are substracting 1 from it(decrementing), and repeating, writing and so on again, so why doesnt it goes backward, 5,4,3,2,1? Why the first number is 1 when the starting was 5? My logic tells me if you start with 5, then print current number and then decrement it, and repeat it again all over , it should go in 5,4,3,2,1 order. function doItAgain(message) { var loopCount = 5; while(loopCount > 0) { var target = document.getElementById("target"); target.innerHTML = "LoopCount: " + loopCount + "<br>" + target.innerHTML; console.log("LoopCount is now: " + loopCount); loopCount = loopCount -1; } console.log("End loop"); var button = document.getElementById("looper"); button.value ="Done looping!"; 2) if we look at opposite case and write target.innerHTML = "target.innerHTML + "LoopCount: " + loopCount + "<br>" ; then it writes LoopCount: 5 LoopCount: 4 LoopCount: 3 LoopCount: 2 LoopCount: 1 But if we look the order into syntax, shouldnt it write this? 5 LoopCount: 4 LoopCount: and so on....
