In the provided PHP code example, how can regex be used to achieve the desired outcome?

The issue in the provided PHP code example is that it is trying to extract a specific pattern from a string using regex, but the regex pattern is not correctly defined. To solve this issue, we need to define a correct regex pattern that matches the desired pattern in the string. 

// Incorrect regex pattern
$pattern = '/\d+/';

// Correct regex pattern to match a specific word surrounded by underscores
$pattern = '/_(\w+)_/';

$string = "The _quick_ brown fox jumps over the _lazy_ dog";
preg_match_all($pattern, $string, $matches);

print_r($matches[1]);
