PHP <= malfunctions when first number is less

I have the following code:

$sql = "SELECT * FROM reward_table WHERE _cost <= '$_points' ORDER BY ID DESC";

$result = $conn->query($sql);

while (($row = mysqli_fetch_assoc($result))) {

    $_title = $row_s['_title'];

    $_cost = $row_s['_cost'];

    $_id = $row_s['ID'];

}

When _cost is, for example, set at 8792, and $_points is 8793 then the particular reward shows. When _cost is updated to 8794 then it disappears, which is great - works. However...

When _cost is set to 10000, it also shows? But, when I change _cost to 9000 it disappears as it should. I'm so confused - have I coded something wrong..? It appears like the code will only work if the starting digit of _cost is higher or the same as the starting digit of $_points.

Your help is much appreciated and will stop me going totally insane!

What's the table definition? Is _cost a text field rather than numeric perhaps?

Try CAST(_cost AS UNSIGNED) <= $_points. It sounds like you're doing a string comparison, in which case '10000' < '2'

You're both right. As soon as I changed the row to INT it started working. Always a simple fix! Thanks guys.

Simple fix - my table has _cost as text, rather than integer.
All works fine no need to change code. Fix was table-side.
