Sql query returns only first row

Question

I'm try to display a result of a select query, but i only get duplicate first row not all the rows. here is my code :

$query = "SELECT Email from client";
$result = $db->query($query)->fetch();
foreach($result as $email){
    echo $email["Email"]."\n";
}

Connexion to database works fine.

"Connexion to database works fine." - Which is what, MySQLi_ or PDO? Both have fetch(). php.net/manual/en/mysqli-stmt.fetch.php and php.net/manual/en/pdostatement.fetch.php — Funk Forty Niner

@magentonewbie Ok. I had to be sure as it could have swung either way. — Funk Forty Niner

You need to use fetchALL() as fetch() only returns one row according to the docs:

Fetches a row from a result set associated with a PDOStatement object.

$query = "SELECT Email from client";
$result = $db->query($query)->fetchALL();
foreach($result as $email){
    echo $email["Email"]."\n";
}

The fetch() function only fetches one record.

Modify your code like this:

$query = "SELECT Email from client";
$res = $db->query($query);
while($result = $res->fetch()){
    echo $result["Email"]."\n";
}
