I am trying to count all rows from demos table but i got an error
Catchable fatal error: Object of class mysqli_result could not be converted to string in C:\\xampp\\htdocs\\working_scripts\\test_2.php on line 8
My php code is:
<?php
$con=mysqli_connect("localhost","root","","test");
if (mysqli_connect_errno())
{
echo"Error connecting to database". mysqli_connect_error();
}
$comment_counter=mysqli_query($con,"SELECT COUNT(*) AS total FROM demos");
echo $comment_counter;
?>
You have to use mysqli_fetch_array
<?php
$con = mysqli_connect("localhost","root","","test");
if (mysqli_connect_errno())
{
echo"Error connecting to database". mysqli_connect_error();
}
$result = mysqli_query($con, "SELECT COUNT(*) AS total FROM demos");
if($row = mysqli_fetch_array($result))
{
echo $row["total"];
}
?>
Try this ->
<?php
$con=mysqli_connect("localhost","root","","test");
if (mysqli_connect_errno())
{
echo"Error connecting to database". mysqli_connect_error();
}
$result = mysqli_query($con, 'SELECT COUNT(*) as total FROM demos');
if($row = mysqli_fetch_array($result))
echo $row["total"];
?>
OR
$result = mysqli_num_rows(mysqli_query($con, 'SELECT * FROM demos'));
echo $result;
