如何从php中的数组进行SQL查询？

Question

请告诉我如何才能从数组进行sql查询？

This is my code       
$myString = "Food,FastFood,Chinese";
        $myArray = explode(',', $myString);
        print_r($myArray);

这是上面代码的输出：

Array
(
    [0] => Food
    [1] => FastFood
    [2] => Chinese
)

我的问题是我怎样才能像这样在php中从该数组进行sql查询

$sql="Select * from table where FoodCategories=$Food OR FoodCategories=$FastFood OR FoodCategories=$Chinese ";

请帮帮我。

Answer 1

尝试这个

$string="Food,FastFood,Chinese";
$array=explode(',', $string);
$array = implode("','",$array);
echo $query="Select * from table where FoodCategories IN ('".$array."')";

Answer 2

您可以使用IN条件创建一个SQL语句。 从MySQL- MySQL IN-Condition查看官方文档。

编辑 ：这将是您的新查询：

// you first have to implode your array and add quotes for each array item
$string = "'" . implode("','", $myArray) . "'";
// now you can create your new query
$sql = "Select * from table where FoodCategories IN ($string)";

Answer 3

你可以用in

尝试以下

$data = "'".implode("','",$myString)."'";
sql="Select * from table where FoodCategories in($data)";

Answer 4

用简单的方法试试这个:)

$myString =array("Food","FastFood","Chinese");
// make them together with ', '
$userStr = implode("', '", $myString );
$query="SELECT * FROM table WHERE FoodCategories in ('$userStr')";
