I'm really having an issue with this question, someone please tell me how to properly write this code. I'm in a programming fundamentals class, and I have no Idea how to do this, and I need a PHP pro, who knows their stuff. Thank you!

$a = 100;
$b = 101;
$temp = $a;
$a = $b;
$b = $temp;
if ($a >= $b) {
echo "a is not smaller than b";
} else {
echo "a is smaller than b";
}

Front End Web Development Techdegree Student 7,651 PointsThis is the entire question here :
Create two variables called $a and $b. Set $a to 100 and $b to 101. Then write some logic to swap the values of the two variables. You can use a temp variable called $temp to store one of the variables when you are swapping the value of the variable. Once the swapping is done, make sure you destroy $temp.
Then
Write an if check to see if to see if $a is bigger or equals to $b, if it is bigger or equals then print “a is not smaller than b”, else print “a is smaller than b”

If you are still fuzzy on the syntax of this, I'd advise on watching the video that discusses a conditional statement.

Front End Web Development Techdegree Student 7,651 PointsCould you please write the code out for me, and then screen shot it? Please! :)

23,118 PointsNo, I'm not writing out the code for you. It kinda goes against learning how to code.
Having said that you wrote out the sudo code like so...
if $a is greater or equal to $b: echo "a is not smaller than b" else: echo "a is smaller than b"
writing something like this is a foundational level operation. If you do not know how to write this you really should watch the video on how to write a conditional statement. That one line above is the answer to the question, turn it into PHP, and you'll be good to go.
