Question

I want to access the data in the php array. I have tried array[0] and array[‘Name’] but i dont get an output. here is my code:

session_start();
$user = $_SESSION['username'];
$sql_1 = "SELECT UserID FROM users WHERE username=$user";
$result_1 = mysqli_query($sql_1);
$uID = mysqli_fetch_array($result_1);
if ($uID=NULL) {
    echo 'null';
} else {
    echo $uID[0];
}

Now I am not getting any output from the echo command. So what am i doing wrong here?

Answer 1

The Part if ($uID=NULL) is always true[UPDATED:false], because you’re doing an assignment rather than a comparism (that would be if ( $uID == NULL ))
