Why Does My MySQL Integer Field Return as a String in PHP?

MySQL Integer Field Returns String in PHP

You're experiencing an issue where an integer field from a MySQL database is being returned as a string when accessed in PHP. This occurs because PHP automatically coerces MySQL data types to their corresponding PHP equivalents, and for integer fields, this results in a string.

Solution:

To resolve this, you need to explicitly convert the returned string back to an integer. This can be achieved using the built-in PHP functions (int) or intval():

$result = $query->fetch_assoc();
$id = (int) $result['userid']; // Cast to integer using (int)

or

$result = $query->fetch_assoc();
$id = intval($result['userid']); // Cast to integer using intval()

The above code will ensure that $id is an integer and can be used accordingly in your code.
