<?php
$i = 0;
while(conditionals...) {
if($i == 0)
print "<p>Show this once</p>";
print "<p>display everytime</p>";
$i++;
}
?>
Would this only show "Show this once" the first time and only that time, and show the "display everytime" as long as the while loop goes thru?
Yes, indeed.
You can also combine the if and the increment, so you won't forget to increment:
if (!$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, as long as nothing in the loop sets $i back to 0
Yes it will, unless the conditions are false from the start or $i was set to 0 inside the loop
