Show table with results grouped 3 by 3 - php

Question

I am trying to show results that I get from a SQL table, it is this:
what I want to do is show results 3 by 3, like this:
I mean a table for every 3 results that the "assigned_bank" field matches, and if there are 4 results with the same number in "assigned_bank", I also show it in that same table, that is; one table for each different "assigned_bank" id.
I've been trying most of the day and the closest thing I've come to is this:
This is my last code:
<?php
$tables = sizeof($search) / 3;
for ($i = 0; $i < $tables; $i++) {
?>
<table class="table customers">
<thead class="thead-blue">
<tr>
<th scope="col-xs-2">Name</th>
<th scope="col-xs-2">Lastname</th>
<th scope="col-xs-2">Bank ID</th>
</tr>
</thead>
<tbody>
<?php
foreach ($search as $item){
echo '<tr align="left">';
echo '<td class="col-xs-2">' . $item["p_name"] . '</td>' . "\r\n";
echo '<td class="col-xs-2">' . $item["p_lastname"] . '</td>' . "\r\n";
echo '<td class="col-xs-2">' . $item["assigned_bank"] . '</td>' . "\r\n";
echo '</tr>';
}
?>
</tbody>
</table>
<?php
echo "\r\n";
}
?>
Thank you very much for any possible help or comments and thank you for taking the time to respond.

<?php
$result = array();
foreach ($search as $key => $item) {
$result[$item['assigned_bank']][$key] = $item;
}
foreach($result as $key=>$search_items){
echo '<table class="table customers" border="2" >
<thead class="thead-blue">
<tr>
<th scope="col-xs-2">Name</th>
<th scope="col-xs-2">Lastname</th>
<th scope="col-xs-2">Bank ID</th>
</tr>
</thead>
<tbody>';
foreach($search_items as $skey=>$item){
echo '<tr align="left">';
echo '<td class="col-xs-2">' . $item["p_name"] . '</td>' . "\r\n";
echo '<td class="col-xs-2">' . $item["p_lastname"] . '</td>' . "\r\n";
echo '<td class="col-xs-2">' . $item["assigned_bank"] . '</td>' . "\r\n";
echo '</tr>';
}
echo '</tbody>
</table>';
}
<?>

You can use order by on assigned_bank column with ascending order:
SELECT p_name, p_lastname, assigned_bank FROM your_table order by
assigned_bank asc
