Of course this code won't display anything cos no condition has been met, besides you will need a session or fetch the user id from the database first and then you can check if the condition is met. Look at the post above by silento, that's what you should do first at user login, you can also read on php sessions

Markydave glad to know that you are interested in programming and you might want to follow the advice given above, try to read on tutorials online so you can get a hang on it but below is what you need and I hope it is not too complex for you to understand. Note that I assume that you have included your database connection, hence the need for "$con" in the sample.

cheers

<?php

$user_id = $_POST['userid']; // get id from form and pass to variable

if($user_id == "markydave" // compare variable

{
echo "hello markydave";

}


else if($user_id == "seun" // compare variable

Youre going to need a working database for this. and a logged session. is google not working in ur area? better make a research my guy, it gon be lyk this
<?php

//lets say i have connfcted the sql. pl
$id=$_SESSION['USER'];

//this will get id of the user stored in a session dpdp

// a db to select n*me from user where id="$id"
this will fetch only name, then rep the name with $name

//then replace the hello user with hello $name

Pardon my typing and bad syntax, i am typing with a small tecno phone that has no clear button

You need to paste your codes here, enough codes that can help someone easily identity the problem... I can't only assume a whole lot of things here....

However, assuming u already have a table in your database, and that the user login is through a form...

Hence, using simplified codes, without considering security, no PDO, etc...

<?php
//Check if login details was submitted and proceed
if(isset(POST['username']) && isset($_POST['password'])){
$username = trim(POST['username']);
$password = trim(POST['password']);

//Check for the login details in your database
$sql = "SELECT * FROM yourTable WHERE username = '$username' AND password = '$password' LIMIT 1 ";
$result = $db_conn->query($sql);

//Check if the sql query returned any row
if($result->num_rows>0){
//Assign the returned data to an associate array
$row = $result->fetch_assoc();

//get db id and assign it to $id
$id = $row['id'];

//Check if $id is 7?
if($id == 7){
echo "Welcome Mr. 7 <br>";
}else{
echo "Your id is not 7, get out! <br>";
}
}
}
?>

Note: I just typed away from my phone... I didn't run to check if any error...
