Question

我有这个查询SQL DB的代码。我想将数组中的值存储为变量，然后我可以在页面的其他地方回显PHP。

任何想法我做错了什么？结果就像“数组”一样。

 <?php
$con=mysqli_connect("localhost","root","root","mongolwar");
$result = mysqli_query($con,"SELECT * FROM userdata");

$total = ['player_total'];

mysqli_close($con);
?>

<?php 

echo $total;

;?>

我找到了解决方案：

    <?php

$con=mysqli_connect("localhost","root","root","mongolwar");
$result = mysqli_query($con,"SELECT * FROM userdata");

while($row = mysqli_fetch_array($result)) {

$total = $row[player_total];

}

mysqli_close($con);


?>

<?php 

echo $total;

;?>

Answer 1

在这种情况下，您说$total = ['player_total']，您可能需要$total = $result['player_total'];

运行此代码，它会让你接近你想要的东西，然后希望你可以完全接受它：

<?php
    $con=mysqli_connect("localhost","root","root","mongolwar");
    $result = mysqli_query($con,"SELECT * FROM userdata");

    mysqli_close($con);

    print_r($result);

?>

另外，你应该真正研究准备好的陈述。

将SQL结果存储为var
