how do i use LIKE in PDO?

Question

我正在尝试在 php 中将 LIKE 与我的 sql 查询一起使用。但它仅在搜索查询完全相同时显示。这是我下面的代码。<?phpinclude 'config.php';$sql = "select name, skill, Location, phone, rating FROM searchResults WHERE skill LIKE :search OR name LIKE :search order by id desc";try {    $dbh = new PDO("mysql:host=$dbhost;dbname=$dbname", $dbuser, $dbpass);      $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);    $stmt = $dbh->prepare($sql);      // $stmt->bindParam("search", $_GET['search']);    $stmt->bindValue(":search", $_GET['search'], PDO::PARAM_STR);    $stmt->execute();    $employees = $stmt->fetchAll(PDO::FETCH_OBJ);    $dbh = null;    echo '{"items":'. json_encode($employees) .'}'; } catch(PDOException $e) {    echo '{"error":{"text":'. $e->getMessage() .'}}'; }?>请帮忙

Answer 1

在你的例子中，你可以简单地做

$stmt->bindValue(":search", "%" . $_GET['search'] . "%", PDO::PARAM_STR);

Answer 2

你需要%在你的 MySQL 查询中加上你的搜索词。检查https://dev.mysql.com/doc/refman/8.0/en/pattern-matching.html
