Introducing the Practice

2:35 with Alena Holligan

Let's practice some PHP if/else Statements to solidify your growing knowledge and make it stick.

It's okay to make multiple attempts before coming to a solution. That struggle to remember what you've learned , and apply it to the situation, is what causes the knowledge to take root.

    Hey everyone, Alena here. 0:04
    Practice is vital to becoming a proficient developer. 0:07
    It solidifies what you've learned causing it to stick in your memory. 0:10
    With deliberate practice, it becomes quicker and 0:14
    easier to solve the challenges you'll face everyday. 0:17
    So let's practice some PHP. 0:20
    This practice session is intended to follow the third stage 0:23
    of the PHP basics course. 0:26
    If you haven't taken that course already, or find this practice session 0:28
    too difficult, then review stage three of the PHP basics course. 0:32
    Check the notes associated with this video for additional links and resources. 0:37
    Let's review the challenge. 0:43
    I've included some initial variables at the start of the index.php file. 0:45
    There are six steps to completing this challenge. 0:51
    The file includes a comment for each step. 0:54
    Add your code below each comment. 0:57
    Step one, create a variable named myLines and 1:00
    set its value equal to the integer 40000000. 1:04
    4 followed by six 0s. 1:08
    Step two, use an if statement to check whether myLines is greater than $osx. 1:11
    If so, display the string. 1:18
    Step three, add an else if statement to check whether myLines 1:22
    is greater than $android, and if so, display the string. 1:26
    Step four, add another else if statement to check whether myLines is 1:32
    greater than $apollo11, and if so, display the string. 1:37
    Step five, add a final else statement to display the string. 1:43
    And finally step six, test your code by changing the value of myLines 1:48
    until you have reached all possibilities. 1:53
    At any point, to test out what you've done, go to View > Show Console. 1:56
    And type php index.php. 2:03
    There are no errors and nothing is displayed to the screen. 2:06
    Remember, it's okay to make multiple attempts before coming to a solution. 2:12
    That struggle to remember what you've learned and 2:17
    apply it to the situation is what causes the knowledge to take root. 2:19
    If you do get stuck, 2:24
    I've included additional resources in the notes associated with this video. 2:25
    Go ahead and give it a try, and I'll show you my solution in the next video. 2:30
