I would like to echo the number of people registered on my website only the code that I have does not work, it gives me back that it can't be converted to string. Also when I make it a function to call in my HTML I get error that $connection is undefined
require_once("connect.php");
$sql = "SELECT * FROM persons";
if ($result=mysqli_query($connection, $sql)){
$rowcount = mysqli_num_rows($result);
mysqli_free_result($result);
return $result;}
How do I get this in a function that I can call on my page that prints the number of people registered?
First of all you should use count
because of speed issues:
$sql = "SELECT COUNT(id) FROM persons";
To write a function that returns the number, you can do something like
function registredMemberCount ($connection)
{
$sql = "SELECT COUNT(id) FROM persons";
$result = mysqli_query($connection,$sql);
$rows = mysqli_fetch_row($result);
return $rows[0];
}
and call it with
registredMemberCount($connection);
require_once("connect.php");
function blah()
{
global $connection;
$sql = "SELECT COUNT(*) FROM persons";
if ($result=mysqli_query($connection, $sql)){
$row= mysqli_fetch_array($result);
$rowcount = $row[0];
mysqli_free_result($result);
}
return $rowcount;
}
echo blah();
Lets see this,
require('connect.php');
function total_num_users(){
$sql = "SELECT * FROM persons";
$result = mysqli_query($connection,$sql);
$count = mysqli_num_rows($result);
return $count;
}
And you can call and echo it like this.
echo total_num_users();
