PHP file not retrieving data from my mySQL database server

Question

I am currently coding an Android app for login and registration. I have discovered that the error is coming from my php file as when I try and just open the file it does not fetch any of the data even though it is connecting correctly to the database.

This is my PHP code here:

<?php
$con=mysqli_connect("mysql7.000webhost.com","a3736257_root","********","a3736257_UD");

    if ($con->connect_error) {
         die("Connection failed: " . $conn->connect_error);
    } 
    //echo 'connection successful';

$username = 'jack';
$password = 'jackjack';

$statement = mysqli_prepare($con, "SELECT * FROM Parent WHERE username = ?  AND password = ?");
mysqli_stmt_bind_param($statement, "ss", $username, $password);
mysqli_stmt_execute;

mysqli_stmt_store_result($statement);
mysqli_stmt_bind_result($statement,$parentID ,$username, $password, $email, $created, $rewardOwed);
$parent = array();

while(mysqli_stmt_fetch($statement)) {
    $parent[username] = $username;
    $parent[password] = $password;
            $parent[email] = $email;
            $parent[created] = $created;
}
echo json_encode($parent);

mysqli_stmt_close($statement);

mysqli_close($con); ?>      

This is the output when I execute the code

Answer 1

The mysqli_stmt_execute function doesn't know what you want it to execute unless you provide it with the prepared statement. Also functions should have parenthesis () .

So:

mysqli_stmt_execute;

should be

mysqli_stmt_execute($statement);
