我正在尝试编辑我的搜索栏，以便用户可以搜索用逗号分隔的值。它调用mySQL数据库。有人能帮忙吗？我相信这一定很明显，但我是新来的。非常感谢。
搜索页面：

您可以执行以下操作：
$searchArray = explode(',', $_POST['search']);
然后foreach遍历该数组，为每个项目运行搜索查询，附加每个查询的结果，然后显示完整的列表。
你能分解搜索然后使用这些值吗？
$search = $_POST['search'];
$myNewSearch = explode(",",$search);
$searchLen = count($myNewSearch);
for($i = 0; $i < $searchLen; $i++){
Select * from profiles WHERE (
first_name LIKE '%{$myNewSearch[$i]}%'
...
}
它有点长，但它可以让你在没有逗号的情况下输入所有内容。
