回声编号计数器 - 删除前导零

Question

At the moment I have a numbering system that brings back the following:

Using:

<?php echo $slide->counter; ?>

01 02 03 04 05

What can I add to the above php to get rid of the zero, so that it displays:

1 2 3 4 5

Answer 1

This should work...

printf('%d', $slide->counter);
