PHP, PDO. How do I get the default fetch mode?

Question

It is possible to set the default fetch mode using:

$dbh->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, $fetch_mode);

Consider such a function:

<?php

function do_something($fetch_mode = /* default fetch mode */){
  // Do something
}

?>

Here I need to GET the default fetch mode. How do I get it?

Answer 1

echo $dbh->getAttribute(PDO::ATTR_DEFAULT_FETCH_MODE);

这为您提供了一个 int，您可以使用手册中提供的列表自己进行映射。
