This is my code

)

My question is how can I make sql query from this array in php like

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

Please help me out.

Answer 1

try this

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

Answer 2

You could create an SQL Statement with an IN-Condition. Check the official doc from MySQL - MySQL IN-Condition .

EDIT : This would be your new query:

// 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

You can use in

Try the following

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

Answer 4

Try this with easy way :)

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