警告：（）提供的foreach無效參數

Question

這是我所添加的代碼，它只是說，誤差

警告：（）提供的foreach無效參數

<?php 
include '../../config/Database.php'; 
$pdo = Database::connect(); 
$q = "select branch_add,branch_Address,branch_landNo , branch_email , Fname from db_thisurienterprice.tbl_employee , db_thisurienterprice.tbl_branch , db_thisurienterprice.tbl_login where employeeBranch = branch_ID and NIC = " .$_SESSION['username'] ."limit 1"; 

foreach ($pdo->query($q) as $row) { 

    echo '<label class="control-label">'.$row['Fname'].' </label> <br/>'; 
    echo '<label class="control-label">'.$row['branch_add'].' </label> <br/>'; 
    echo '<label class="control-label">'.$row['branch_Address'].' </label> <br/>'; 
    echo '<label class="control-label">'.$row['branch_landNo'].' </label> <br/>'; 
    echo '<label class="control-label">'.$row['branch_email'].' </label> <br/>'; 


} 
Database::disconnect(); 
?> 

但如果我在查詢中刪除「limit 1」，這可以正常工作。但那次同樣的記錄重複了3次。什麼似乎是這個問題？

您的查詢需要limit和$_SESSION['username']之前，空間必須在引號

$q = "select branch_add,branch_Address,branch_landNo , branch_email , Fname from db_thisurienterprice.tbl_employee , db_thisurienterprice.tbl_branch , db_thisurienterprice.tbl_login where employeeBranch = branch_ID and NIC ='" .$_SESSION['username']."' limit 1"; 

您需要從您的結果集，然後使用foreach循環將日期

foreach ($pdo->query($q) as $row) { 

     echo '<label class="control-label">'.$row['Fname'].' </label> <br/>'; 
     echo '<label class="control-label">'.$row['branch_add'].' </label> <br/>'; 
     echo '<label class="control-label">'.$row['branch_Address'].' </label> <br/>'; 
     echo '<label class="control-label">'.$row['branch_landNo'].' </label> <br/>'; 
     echo '<label class="control-label">'.$row['branch_email'].' </label> <br/>'; 
    }
