Question

I am new to mysql but have recently tried doing some tutorials to advance my knowledge. Anyways I installed mysql on my ubuntu server as well as phpmyadmin. They both seem to work just fine, I created a database in phpmyadmin called “test” as well as a table called “teddy”.
I put data into the table and I can clearly see it through phpmyadmin.

Now when I try accessing this database via a php script on my ubuntu server, nothing happens. Literally nothing. It reacts the same way as if I had a syntax error (a quick load with nothing displayed).

This is my code… If anyone knows where my mistake is it would be much appreciated.

Thank you

 <?php

   $username='root';
    $password='***';
    $database='test';


   @$db= mysqli_connect('localhost', $username, $password, $database);

if (mysqli_connect_errno())
{
echo 'Error: Could not connect';
exit;

 }

 $query= "select * from test";

$result= $db->query($query);

$num_results= $result->num_rows;

echo $num_results;


  ?>

Problem was the table was not called test but teddy so putting in this code worked.
“SELECT * FROM ‘teddy'”;

$db= new mysqli('localhost', $username, $password, $database);

 if (mysqli_connect_errno())
 {
echo 'Error: Could not connect';
exit;

 }

 $query = "SELECT * FROM 'teddy'";

  $result = $db->query($query);
 if ($result) {
  $num_results = $result->num_rows;

  echo $num_results;
    } else {
  echo "Query failed: {$db->error}\n";
   }


  ?>

Answer 1

$result= $db->query($query); is probably returning false for some reason.

Try:

$query = "select * from teddy";

$result = $db->query($query);
if ($result) {
    $num_results = $result->num_rows;

    echo $num_results;
} else {
    echo "Query failed: {$db->error}\n";
}
