pdo all rows does not fetch outside while loop - php

Question

I'm trying to fetch all rows using this below coding. Here you can see echo $row['UserName']; and echo $row['Address']; i can get all the username and address from database. But when i use this coding ($uname = $row['UserName'];echo $uname; and $uaddress = $row['Address'];echo $uaddress;) outside of while loop it always fetch the last row values. My question is how to fetch all row values outside of while loop?
<?php
include('config.php');
try
{
$stmt = $conn->prepare('SELECT * FROM ebusers');
$conn->errorInfo();
$stmt->execute();
while($row = $stmt->fetch())
{
echo "<a target=_blank href='edit.php?id=". $row['UserID'] ."'>Edit</a>";
echo "<br>";
echo "<a target=_blank href='delete.php?id=". $row['UserID'] ."'>Delete</a>";
echo $row['UserName'];
$uname = $row['UserName'];
echo "<br>";
echo $row['Address'];
$uaddress = $row['Address'];
echo "<br>";
}
}
catch(PDOException $e)
{
'Error : '.$e->getMesssage();
}
echo $uname;
echo $uaddress;
?>

Answer 1

Just pass them into an array
while($row = $stmt->fetch())
{
echo "<a target=_blank href='edit.php?id=". $row['UserID'] ."'>Edit</a>";
echo "<br>";
echo "<a target=_blank href='delete.php?id=". $row['UserID'] ."'>Delete</a>";
echo $row['UserName'];
$uname[] = $row['UserName']; // An array of usernames...
echo "<br>";
echo $row['Address'];
$uaddress[] = $row['Address']; // An another array of addresses
echo "<br>";
}
//Below two statements prints all usernames and addresses
print_r($uname); // or you can access like echo $uname[2] to view the second username
print_r($uaddress); // similarly you can do like that as you did for $uname..
//or if you want to loop through individually , you can make use of a foreach construct
foreach($uname as $usernames)
{
echo $usernames."<br>";
}

During the while loop, the $row variable get overwritten each time it executed.
You may have a try on FetchAll which prepares the array for you.
