使用PHP和MySQLi实现数据库搜索的多字符串

$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

<form method="GET" action="search.php">
    <input type="text" name="keywords" placeholder="输入关键字">
    <input type="submit" value="搜索">
</form>

$keywords = $_GET['keywords'];
$keywordArray = explode(" ", $keywords);

$sql = "SELECT * FROM table_name WHERE ";
foreach ($keywordArray as $keyword) {
    $sql .= "column_name LIKE '%$keyword%' AND ";
}
$sql = rtrim($sql, "AND ");

$result = $conn->query($sql);
if ($result->num_rows > 0) {
    // 处理查询结果
} else {
    echo "没有找到匹配的结果";
}

while ($row = $result->fetch_assoc()) {
    // 处理每一行的数据
    echo $row['column_name'];
}
