I have an array of integers, how do I use each one in a mysql query (in php)?

I am trying to create some filtering function and I would like to know if it is possible, within a mysqli query, to check if the table row has a value equal to just one of those in the array. I hope the code will make it clearer:

$age=array(37,35);
$query = mysqli_query($link, "SELECT * FROM users WHERE age = $age");

So I want the query to return all the rows of users whose age is either 37 or 35, but the above code doesn’t work.

Using

...WHERE age = 35 OR age = 37"

Won’t do, because I want it to be dynamic so to speak.

Thanks

Use SQL’s IN() clause.

SQL Example:

SELECT * FROM users WHERE age IN (35, 37)

PHP Example:

$query = "SELECT * FROM users WHERE age IN (" . implode(',', array_map('intval', $age)) . ")";

Note: Be mindful of SQL Injection.
