For Loops in PHP it seems right. have tried everything


i have tried almost everything on here in the Q and A forum; but my echo keeps staying blue. I have even googled it because I'm desperate to understand this, but it simply isn't working.

here is my code.

<? php
for ( $i = 0; $i <= 10;$i = $i + 1)
echo $i;


which exercise is this? and whats the error?



Try refreshing your browser's webpage and copy paste your code. It happened to me too but this should work.
