PHP After every NTH in DIV LOOP - loops

Question

Hi I want to add content after every 3rd div in the loop. Here is below code but I am not getting even render content "Hi this is the 3d div"
Its not detecting every 3rd div.
<?php
function q_list_item($q_item)
{
$count = 0;
$this->output('<DIV>');
$this->my_items;
$this->output('</DIV>');
$count++;
if($count % 3 == 0) {
echo 'Hi this is the 3rd div';
}
}
?>
----[Actual Function]-----------------------------------------------
<?php
function q_list_item($q_item)
{
$this->output('<DIV CLASS="qa-q-list-item'.rtrim(' '.#$q_item['classes']).'" '.#$q_item['tags'].'>');
$this->q_item_stats($q_item);
$this->q_item_main($q_item);
$this->q_item_clear();
$this->output('</DIV> <!-- END qa-q-list-item -->', '');
}
?>

Answer 1

You are resetting the $count to 0 at the top of this function, so it will always be 1 when you run the if statement at the end of the function.
This may help with your issue, although I can't tell if your code is in a class or not as it doesn't look like it is, but you are using $this-> in there. Essentially, move the instantiation of the counter outside of the function:
<?php
$q_list_count = 0;
function q_list_item($q_item)
{
$q_list_count++;
$this->output('<DIV>');
$this->my_items;
$this->output('</DIV>');
if($q_list_count % 3 == 0) {
echo 'Hi this is the 3rd div';
}
}
?>

Answer 2

<?php
$count = 0;
function q_list_item($q_item)
{
$this->output('<DIV>');
$this->my_items;
$this->output('</DIV>');
$count++;
if($count % 3 == 0) {
echo 'Hi this is the 3rd div';
}
}
?>
initialize the $count outside the loop, otherwise count will always be 1 when it reaches the if statement
