How can I achieve this. Thanks in advance.
if($result2->num_rows > 0){
echo '<table width="100%" bgcolor="#FFFFFF" cellpadding="0" cellspacing="0" border="1" class="db-table" boarder-collapse ="collapse">';
echo '<tr><th>STUDENT_NAME</th><th>CLASS</th><th>ID_NUMBER</th><th>ADDRESS</th><th>CITY</th><th>STATE</th><th>ZIP</th><th>COUNTRY</th><th>PHONE</th><th>INSURANCE</th>
<th>EMAIL</th><th>MAILING_ADDRESS</th><th>JOINED_ON</th></tr>';
while($rowz2 = mysqli_fetch_assoc($result2)){
echo "<tr>";
foreach($rowz2 as $key=>$value){
echo '<td>',$value,'</td>';
}
echo '</tr>';
}
echo "</table><br/>";
}
else{
echo "<h2>No data based on the entered values</h2>";
}

Answer 1

Use an a tag with mail:
echo '<td>' . $value .'</td>';
Assuming that $value content is an email address
Changes based the code you posted in your comments:
Apparently was a couple of nesting problems but I think what you wanted to say was...
echo "<table>";
while($rowz2 = mysqli_fetch_assoc($result2)){
echo "<tr>";
foreach($rowz2 as $key=>$value){
if($key=='EMAIL') {
echo '<td>' . $value . '</td>';
} else {
echo '<td>' . $value . '</td>';
}
}
echo '</tr>';
}
echo "</table><br/>";
I can't say for sure if that would work as you expect but if a value is retrieved from DB with a field name "EMAIL" then it will be echoed inside a mailto: link.
So whether the field name is EMAIL or you used SELECT this_field, that_field, the_email_field as EMAIL FROM your_table it would bring a working mailto: link in your table.

I cannot comment yet so i will post it here. Check if your database column is 'email' or 'EMAIL' because
if ($key == 'EMAIL')
is case sensitive and as such it will never pass the condition if column is 'email'. If for some reason you need a case insensitive string comparison use:
if (strcasecmp($key, 'EMAIL') === 0)
