MySQL integer field is returned as string in PHP

Question

I have a table field in a MySQL database:

userid INT(11)

So I am calling it to my page with this query:

\"SELECT userid FR         


        

Answer 1

When you select data from a MySQL database using PHP the datatype will always be converted to a string. You can convert it back to an integer using the following code:

$id = (int) $row['userid'];

Or by using the function intval():

$id = intval($row['userid']);
