count number of rows in table using php

Question

I just want to count the number of rows in a table that already created in a database using php. I used mysqli(). I need the number of rows in the table as the output.

Answer 1

 query("SELECT columnName from tablename")) {

    /* determine number of rows result set */
     $row_cnt = $result->num_rows;

    printf("Result set has %d rows.\n", $row_cnt);

   /* close result set */
    $result->close();
 }

 /* close connection */
 $mysqli->close();
?>

EDIT:

$result = $db->query("SELECT COUNT(*) FROM `table`");
$row = $result->fetch_row();
echo '#: ', $row[0];
