How Can I Retrieve Numeric Types from MySQL Using PDO Without String Conversion?

Retrieving Numeric Types in MySQL with PDO

Retrieving numeric types from MySQL using PDO can be challenging due to the default behavior of returning string representations instead of numeric values.

PDO::ATTR_STRINGIFY_FETCHES Attribute

The PDO class offers the PDO::ATTR_STRINGIFY_FETCHES attribute to control the conversion of numeric values to strings. However, this attribute is not supported for the MySQL driver.

Disabling Prepared Statement Emulation

To correctly retrieve numeric types, you need to disable prepared statement emulation from PDO. This can be achieved by setting PDO::ATTR_EMULATE_PREPARES to false when creating the PDO object:

$pdo = new PDO($dsn, $user, $pass, [
    PDO::ATTR_EMULATE_PREPARES => false,
]);

With prepared statement emulation disabled, PHP will utilize the native MySQL data types, including numeric types. Henceforth, int values retrieved from the database will no longer be converted to strings.

Conclusion

To ensure consistent handling of numeric types, it is recommended to disable prepared statement emulation when working with PDO and MySQL. By doing so, you can reliably retrieve numeric values in their true format, enhancing the accuracy and usability of your data processing.
