In PHP, there are three ways to convert month numbers to names: using the date function with mktime, manual array mapping, and using the Carbon library. 1. Use date and mktime to obtain English or localized month names through system functions; 2. Array mapping is suitable for fixed mapping relationships, flexible control and environment-dependent; 3. The Carbon library is suitable for modern framework projects, supports internationalization and chain calls, which is more elegant and convenient.

In PHP, it is quite common to convert month numbers into corresponding names. For example, if you have a form that enters numbers from 1 to 12, and you want to display them in "January" or "January" in Chinese. Here are a few practical methods.

Use date function to cooperate with mktime

This is the most basic and commonly used method. You can construct a timestamp through mktime and then use date('F') to get the full month name (English):

 $monthNumber = 5;
echo date('F', mktime(0, 0, 0, $monthNumber, 10)); // Output May

If you need abbreviation, such as "May" becomes "May" (yes, the English abbreviation and full name are the same), but it should be noted that this method outputs the English name by default.
If you want to change to Chinese or other languages, you need to set up a localized environment, such as:

 setlocale(LC_TIME, 'zh_CN');
$monthNumber = 3;
echo strftime('%B', mktime(0, 0, 0, $monthNumber, 10)); // Output March

• date('F') : Returns the full English month name
• strftime('%B') : Returns the month name of the corresponding language according to the system locale
• mktime parameter order is hour, minute, second, month, day, year

Manual mapping using array

If you don't want to rely on time functions, or just need a fixed Chinese-English mapping, you can directly define an array to convert:

 $months = [
    1 => 'January', 'February', 'March', 'April',
    'May', 'June', 'July', 'August',
    'September', 'October', 'November', 'December'
];

echo $months[7]; // Output July

This method is simple, fast and controllable, especially suitable for situations where you need to customize multilingual or alias:

 $monthsZh = [
    1 => 'January', 'February', 'March', 'April',
    'May', 'June', 'July', 'August',
    'September', 'October', 'November', 'December'
];

• Not affected by server time zone
• Easier to control output format
• Suitable for front-end unified mapping

Use the Carbon library (suitable for Laravel or modern projects)

If you are using Laravel or have installed the Carbon extension library, you can handle dates more elegantly:

 use Carbon\Carbon;

$monthNumber = 11;
echo Carbon::create(null, $monthNumber)->format('F'); // November

Carbon's PHP-based DateTime class encapsulates many convenient methods and supports chain calls. For internationalization, it can also be handled in this way:

 Carbon::setLocale('zh');
echo Carbon::create(null, $monthNumber)->formatLocalized('%B'); // November

• Carbon needs to be installed and introduced first
• It is more convenient to support internationalization
• More suitable for modern framework projects

Basically these methods. Just choose different implementation methods in different scenarios. For example, small projects have the fastest direct array mapping, and it is more standardized to use Carbon in the framework, and it is enough to use date() and mktime() for temporary processing.
