php - 如何返回字符串是属性子字符串的所有行

Question

我在我的网站上搜索用户。我想返回名称包含输入的字符串或等于字符串的所有用户行。

它看起来像这样:

$name = $_POST['name'];    
"SELECT * FROM users WHERE name='$name' OR **'$name' is substr of name**"

Answer 1

使用LIKE:

$name = $_POST['name'];
$query = "SELECT * FROM users WHERE name LIKE '%$name%'";

使用 PDO:

$name = $_POST['name'];
try 
{
    $dbh = new PDO("mysql:host=YourHost;dbname=YourDatabase", $username, $password);    
    $stmt = $dbh->query("SELECT * FROM users WHERE name LIKE '%$name%'");    

    //fetch your data.....   

    $dbh = null;
}
catch(PDOException $e)
{
    echo $e->getMessage();
}
