How can the setlocale() function be used to address problems with str_word_count function in PHP, particularly with regards to locale-dependent strings?

The issue with the str_word_count function in PHP arises when dealing with locale-dependent strings, as it may not accurately count words in languages with special characters or different word boundaries. To address this problem, the setlocale() function can be used to set the desired locale for the script, ensuring that the str_word_count function interprets the strings correctly. 

// Set the desired locale for the script
setlocale(LC_CTYPE, 'en_US.UTF-8');

// Use str_word_count function with the locale set
$string = "Hello world";
$wordCount = str_word_count($string);

echo $wordCount; // Output: 2
