我希望通過回聲查看$ result的查詢

Question

我試圖從我的用戶表中使用查詢獲取所有數據，並且我想通過回顯顯示它，並且這是我的代碼，請幫助

<?php 
    error_reporting(0); 
    require_once "helperfindercon.php"; 
    $user_name = "joseph"; 
    $user_pass = "joseph"; 
    $mysql_qry = "select * from users"; 
    $result = mysqli_query($conn, $mysql_qry); 
    if (mysqli_num_rows($result) > 0){ 
    echo "$result"; 
    } 
    else { 
    echo "error"; 
    } 
?> 

Answer 1

你要（從$result得到的所有記錄，並告訴他們）申請while()內if()： -

if (mysqli_num_rows($result) > 0){ 
    while($row = mysqli_fetch_assoc($result)){ 
    //print_r($row);// now check the array and echo accordingly. 
    foreach($row as $key=>$val){ 
     echo $key.' :-'.$val."\n"; 
    } 
    } 
}

<?php 
error_reporting(0); 
require_once "helperfindercon.php"; 
$user_name = "joseph"; 
$user_pass = "joseph"; 
$mysql_qry = "select * from users"; 
$result = mysqli_query($conn, $mysql_qry); 
if (mysqli_num_rows($result) > 0){ 
    printt_r($result); // should use print_r as its type of array 
} 
else { 
echo "error"; 
} 
?>
