The array does not show the information echo

Question

No I'm doing wrong, I am modifying a system created by someone else but I can not show the information ... This is the code ...

$db = DB::getInstance();
$id = 1;
$query = $db->query("SELECT * FROM users WHERE id = ?", array($id));
$x = $query->results();
echo $x;

The error: Notice: Array to string conversion in...

Answer 1

use print_r($x) instead of echo $x echo is used to print string and numbers but could not print array, you may use var_dump too ... actually var_dump is used to print objects

Answer 2

Try using var_dump (instead of echo) if the return value is an object. For example:

var_dump($x);

Answer 3

use FOR :

$db = DB::getInstance();
$id = 1;
$query = $db->query("SELECT * FROM users WHERE id = ?", array($id));
$x = $query->results();

for ($i=0;$i<count($x); $i++){
        echo $x[$i]."<br/>";
    }
