How can different language variations impact the output of date formatting in PHP when using ICU-/Intl-Locales?

Different language variations can impact the output of date formatting in PHP when using ICU-/Intl-Locales because each language may have its own specific date formatting rules. To solve this issue, you can set the locale using the setlocale() function in PHP before formatting the date to ensure that the date is displayed according to the rules of the specified language.

// Set the locale to the desired language variation
setlocale(LC_TIME, 'fr_FR.UTF-8');

// Format the current date according to the specified locale
echo strftime('%A %d %B %Y');
