Question

I have a table in mysql:

CREATE TABLE user (id INT, name VARCHAR(250));

I query the table:

$result = mysql_query("SELECT id,name FROM user");

I gather the results:

while($row = mysql_fetch_assoc($result) $rv[] = $row;

And I return the data:

echo json_encode($rv);

The problem is that the id returns as string and not int, even before the json_encode. If i force $row[‘id’] = (int)$row[‘id’]; – it works fine.

How can i force mysql to return the correct data type in the $row?

Answer 1

PDO->bindColumn can this

$stmt = $dbh->prepare($sql);

$stmt->bindColumn('int_col', $intVar, PDO::PARAM_INT);
$stmt->bindColumn('string_col', $strVar, PDO::PARAM_STR);

$stmt->execute();

$stmt->fetch(PDO::FETCH_BOUND);

$intVar will be automatically converted to int
