putting in a separator between posts in loop - php

Question

I have the following loop which brings in the title of each post onto my page
html
<?php
if (have_posts()) {
while (have_posts()) {
the_post();
echo '<div class="cell">'.get_the_title().'</div>';
} // end while
} // end if
?>
css
.cell {
display: inline-block;
margin: 0 10px;
}
I want to put a separator between each title/link brought in (not on the ends)
example output
link <div class="separate"></div>
link <div class="separate"></div> link

Answer 1

simple solution using additional flag variable $first
<?php
if ( have_posts() ) {
$first = true;
while ( have_posts() ) {
the_post();
if($first){
$first = false;
} else {
// echo separator
}
echo '<div class="cell">'.get_the_title().'</div>';
} // end while
} // end if
?>

Answer 2

You could put in a <hr> element at the end of your echo like this:
echo '<div class="cell">'.get_the_title().'</div><hr>';

Answer 3

You have to put a counter and compare the counter with posts per page to check if you have reached last post.
You can get posts per page from options table like this:
$default_posts_per_page = get_option( 'posts_per_page' );
Check if you have reached the last post, then don't print out the separator.
$counter = 1;
while ( have_posts() ) {
//your stuffs
if ($counter != $default_posts_per_page) {
//print separator
}
$counter++;
}
