While loop with two if conditions? Last condition only always output '1'?

I have three tables to connect on a single page. The first statement

if (($outcome['EmployeeNo'] = $data ['usn']

shows the numbers we need but the second one only outputs the number '1'.

($outcome['EmployeeID'] = $out['EmployeeID'])):

I'm using this to output them in href.

(viewlogs.php?id=<?= $data['id']; ?>&EmployeeNo=<?= $outcome['EmployeeNo'];?>&EmployeeID=<?= $out['EmployeeID'];)

but my condition is incorrect as it only shows outcome or out = 1.

Does anyone have a suggestion for this?

My complete codes:

 <?php
 session_start();
    if (!isset($_SESSION['username']))
    {
        header('location: login.php');
    die();
    }


  ?>

  <?php 


    try {

        include ("config.php");
        include ("sqlsrv.php");
     }catch(Exception $e){
        die("ERROR:".$e->getMessage());
     } 

    if(isset($_POST['usn']) && $_POST['usn']!=""){ 

         $re = $conn->prepare("SELECT EmployeeID, TimeLogID, RecordDate, RecordTime, Type, ActualTime FROM TA3.dbo.TimeLogs");
         $re->execute();

         $res = $conn->prepare("SELECT EmployeeNo, FirstName, MiddleName, LastName, DateHired, ResignationDate, EmployeeID FROM TA3.dbo.Employees");
         $res->execute();

         $req = $db->prepare("SELECT * FROM students WHERE usn LIKE :usn");
         $req->execute(array(
            'usn'=>'%'.$_POST['usn'].'%'));

         if ($req->rowCount()==0 && $_SESSION['type']=="Super_Admin") { ?>


            <span class="notfound">Student not found? <a class="addstud" href="create.php">add student?</a></span>

            <?php
