<?php $plant_height = 22; do{echo "The plant is $plant_height tall.\n"; $plant_height++; if($plant_height >= 30){echo "And can produce fruit.";}else{}}while($plant_height<=30); I did this as the instruction says ' When the plant is greater than or equal to 30, you should print `"And can produce fruit." ', however, this actually outputs 'The plant is 22 tall. ...... The plant is 29 tall. And can produce fruit.The plant is 30 tall. And can produce fruit.' instead when I change the if condition to '$plant_height >30', the output becomes ' ... The plant is 29 tall. The plant is 30 tall. And can produce fruit.' just like the exercise expects . is there any error in my code ?

when you want to paste your code for us to read it, you should use the button </> on top of the text box and then paste your code where it says so. That way, it’s gonna be easier for us to read it and help you out.

the result will look like this

  $plant_height = 22;

do {
  echo "The plant is $plant_height tall.\n";
    if ($plant_height >= 30) {
    echo "And can produce fruit.\n";
} while ($plant_height <= 30);

your problem is that you didn’t put the if code at the right place, i figured it out by trying to put it in the beginning of the do loop, then after the echo and finally after the $plant_height++ . Coding is all about trying, making mistakes, learning from them and searching the net :wink:
