SELECT * FROM `users` returns only first user

Question

I have a php script:

$sql = $db->query("SELECT * FROM  `users`");
$row = $sql->fetch();
foreach($row as $value){
    echo $value . "<br>";
}

Database 'users' contains 29 records, but I'm getting this:

Answer 1

This is because you're only fetching one record.

Try your code like this:

$sql = $db->query("SELECT * FROM  `users`");
$row = $sql->fetchAll();
foreach($row as $value){
    print_r($value);
    echo "<br>";
}

this way you'll get an array of results, so you loop over the array instead of over the properties.

Answer 2

fetch() returns single elements. Instead try with fetchAll

$row = $sql->fetchAll();

fetchAll — Returns an array containing all of the result set rows

it will return an array hence, remove echo $value and use print_r($value)

fetch — Fetches the next row from a result set only 1 row

Answer 3

mysql fetch() function fetches the next row from a result set only 1 row, whereas mysql fetchAll() function returns an array containing all of the result set rows.

So use fetchAll() to get all the records from resultset, replace this line

$row = $sql->fetch();

with

$row = $sql->fetchAll();
