The foreach loop is skipping the first 2 of 3 items - php

Question

I was wondering whether you guys could help me figure out why this isn't generating the HTML correctly. The variable $wholeTeam is returned from $wpdb->get_results(...) and is confirmed to be of length 3 (because echo count($wholeTeam) is spitting that number out and I've directly looked in the MySQL db to make sure there are 3 rows). For some reason, only the last of the 3 is being generated; the first 2 aren't.
<h2>Current members <span class="title-count"> <?php echo count($wholeTeam) ?> </span></h2>
<div class="row">
<?php
$sandwichTop = '<div class="col-xs-12 col-sm-6 col-md-4 col-lg-3"><img src="/assets/';
$sandwichBottom = '/><button type="button" class="edit-mem-btn wp-core-ui button-primary">Edit</button></div>';
foreach ($wholeTeam as $thisMember)
$sandwichMiddle = $thisMember->picfn . '" id="memberid-' . $thisMember->id . '"';
echo $sandwichTop . $sandwichMiddle . $sandwichBottom;
?>
</div>
gets generated as
<div class="row">
<div class="col-xs-12 col-sm-6 col-md-4 col-lg-3">
<img src="/assets/thepic.png" id="memberid-3"/>
<button type="button" class="edit-mem-btn wp-core-ui button-primary">Edit</button></div>
</div>
</div>

Answer 1

Code
foreach ($wholeTeam as $thisMember)
$sandwichMiddle = $thisMember->picfn . '" id="memberid-' . $thisMember->id . '"';
echo $sandwichTop . $sandwichMiddle . $sandwichBottom;
is equivalent to:
foreach ($wholeTeam as $thisMember) {
$sandwichMiddle = $thisMember->picfn . '" id="memberid-' . $thisMember->id . '"';
}
echo $sandwichTop . $sandwichMiddle . $sandwichBottom;
That's why you echo only once. If you want to echo every foreach iteration:
foreach ($wholeTeam as $thisMember) {
$sandwichMiddle = $thisMember->picfn . '" id="memberid-' . $thisMember->id . '"';
echo $sandwichTop . $sandwichMiddle . $sandwichBottom;
}
