请任何人帮助我。

$result = mysqli_query($conn, $sql);
$rows = mysqli_fetch_assoc($result);

?>

和Body标签

<?php
foreach ($rows as $row) {
   echo $row['name'];
}?>

Answer 1

您应该使用mysqli_fetch_all()一次性获取$rows内的所有行。

$sql = "SELECT * FROM users";
$result = mysqli_query($conn, $sql) or die(mysqli_error($conn);
$rows = mysqli_fetch_all($result);

echo "<pre>";
print_r($rows); // Check your result

Answer 2

您可以将结果存储在数组中，并在正文中使用它，如下所示：

<?php

include('config.php');

$conn = mysqli_connect(DB_HOST, DB_USER, DB_PASS, DB_NAME);

$sql = "SELECT * FROM users";
$result = mysqli_query($conn, $sql);

$rows = array();

while($row = mysqli_fetch_assoc($result)){
    $rows[] = $row;
}

和Body标签

<?php
foreach ($rows as $row) {
 echo $row['name'];
}?>

Php Mysqli_fetch_assoc错误：“警告：非法字符串偏移'名称'在”
