php - 在 PHP 中使用带有变量的 like 子句

Question

我有一个用变量动态构造的查询。我希望我的所有条件也有类似的声明。

我的代码是：

$where .= " AND name=" . "'" . $name . "'";

我想使用：

$where .= " AND name Like "%'.$name.'%";

但我不确定如何构建它。

谢谢

Answer 1

It's looks like you are on the right track. Like this...

$where .= " AND name LIKE '%" . $name . "%'";

But, when adding fields to a string, I find is easier to use the php sprintf() function. As an example:

$where = sprintf("SELECT * FROM Users WHERE name LIKE '%s' AND status='%s'",
    "%" . mysql_real_escape_string($name) . "%",
    "active"
);

Answer 2

你可以简单地做

$where .= " AND name Like '%".$name."'%";

Answer 3

$where .= " AND name Like '%$name%'";

或者

$where .= ' AND name Like "%'.$name.'%"';

Answer 4

像这样 ：

$where .= " AND name LIKE '%".mysql_real_escape_string($name)."%'";
