mysqli_fetch_array using a foreach loop - php

Question

Ive got a pretty basic table named 'customers' with four columns:
ID (primary Auto Increment)
businessName
contactName
contactEmail
I call it with:
$result = mysqli_query($con, "SELECT * FROM customers");
and was using mysqli_fetch_array to display it on the page with a foreach loop:
while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC))
{
echo "<tr>";
foreach ($row as $value) {
echo "<td>" . $value . "</td>";
}
echo "<td><a href='updateform.php?id=" . $row['id'] . "'>Edit</a></td>";
echo "</tr>";
}
Which gives you an 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 it possible to display results differently based on which column (technically now position in the array) they are in? I would like to make a
a href="mailto:bill#microsoft.com"
link when it gets to contactEmail.
What if I wanted to display just one key or value instead of using foreach?
It doesn't seem possible to call
$row['contactEmail']
in the foreach loop
which confuses me since below that I am able to create a link to
$row['id']
If anyone has any ideas how to do this, or if there is a better way to be displaying this information, I'm open to suggestions, as I'm not very good at programming, especially PHP.

Answer 1

Yes! you can just add like this:
while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC))
{
echo "<tr>";
foreach ($row as $key => $value) {
if($key == "contactEmail"){
$mailUrl = "mailto:".$value;
echo "<td>".$value."";
}
else{
echo "<td>" . $value . "</td>";
}
}
echo "<td><a href='updateform.php?id=" . $row['id'] . "'>Edit</a></td>";
echo "</tr>";
}

Answer 2

Yes, You can able to mysqli_fetch_array retrieve data directly using foreach loop. like bellow :
<?php
$result = mysqli_query($con, "SELECT * FROM customers");
?>
<table>
<tr>
<td>Business Name</td>
<td>Contact Name</td>
<td>#</td>
</tr>
<?php
while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC))
{
echo "<tr>";
echo "<td>".$row['businessName']."</td>";
foreach ($row as $key => $value) {
$newValue = $key == "contactEmail" ? ''.$value.'' : $value;
echo "<td>" . $newValue . "</td>";
}
echo "<td><a href='updateform.php?id=" . $row['id'] . "'>Edit</a></td>";
echo "</tr>";
}
?>
