php - mysqli_fetch_array using a foreach loop -

ive got pretty basic table named 'customers' 4 columns:
id (primary auto increment)
businessname
contactname
contactemail

i call with:

$result = mysqli_query($con, "select * customers"); 

and using mysqli_fetch_array display on page foreach loop:

while ($row = mysqli_fetch_array($result, mysqli_assoc)) {         echo "<tr>";     foreach ($row $value) {         echo "<td>" . $value . "</td>";     }     echo "<td><a href='updateform.php?id=" . $row['id'] . "'>edit</a></td>";     echo "</tr>"; } 

which gives array like:

array ( [id] => 1 [businessname] => microsoft [contactname] => bill gates [contactemail] => bill@microsoft.com ) array ( [id] => 2 [businessname] => amazon [contactname] => jeff bezos [contactemail] => jeff@amazon.com )  

is possible display results differently based on column (technically position in array) in? make

a href="mailto:bill@microsoft.com"   

link when gets contactemail.
if wanted display 1 key or value instead of using foreach?
doesn't seem possible call

$row['contactemail']  

in foreach loop confuses me since below able create link

$row['id'] 

if has ideas how this, or if there better way displaying information, i'm open suggestions, i'm not @ programming, php.

yes! can add this:

while ($row = mysqli_fetch_array($result, mysqli_assoc)) {         echo "<tr>";     foreach ($row $key => $value) {         if($key == "contactemail"){           $mailurl = "mailto:".$value;           echo "<td><a href=".$mailurl.">".$value."</a>";         }         else{           echo "<td>" . $value . "</td>";         }     }     echo "<td><a href='updateform.php?id=" . $row['id'] . "'>edit</a></td>";     echo "</tr>"; }
