Show this once\";
print \"display everytime
\";
$i++;
}

Yes, as long as nothing in the loop sets $i back to 0
Yes, indeed.
You can also combine the if and the increment, so you won't forget to increment:
if (!$i++) echo "Show once.";
Rather than incrementing it every time the loop runs and wasting useless resource, what you can do is, if the value is 0 for the first time, then print the statement and make the value of the variable as non-zero. Just like a flag. Condition, you are not changing the value of the variable in between the loop somewhere. Something like this:
<?php
$i = 0;
while(conditionals...) {
if($i == 0){
print "<p>Show this once</p>";
$i=1;
}
print "<p>display everytime</p>";
}
?>
Yes it will, unless the conditions are false from the start or $i was set to 0 inside the loop
