How to convert digital month to English month in php

In PHP development, we often encounter the situation of converting digital months into English months. This is a common requirement because different countries and languages ​​use different ways of representing months. For example, in the United States and the United Kingdom, people usually use English month names to indicate time, while in France and Germany, people usually use month names in their local languages. This article will introduce how to use PHP to convert month numbers into English month names.

First, we need to define a PHP array to store the month name. In this array, we can use English month names as keys and numeric months as values. For example, we can use the following code to define an array containing 12 month names:

$month_names = array(
    "January" => 1,
    "February" => 2,
    "March" => 3,
    "April" => 4,
    "May" => 5,
    "June" => 6,
    "July" => 7,
    "August" => 8,
    "September" => 9,
    "October" => 10,
    "November" => 11,
    "December" => 12
);

Through this array, we can get the corresponding English month name based on the digital month. For example, if we want to convert the numeric month "5" to an English month name, we can use the following code:

$month_names = array(
    "January" => 1,
    "February" => 2,
    "March" => 3,
    "April" => 4,
    "May" => 5,
    "June" => 6,
    "July" => 7,
    "August" => 8,
    "September" => 9,
    "October" => 10,
    "November" => 11,
    "December" => 12
);

$month_number = 5;

$month_name = array_search($month_number, $month_names);

echo $month_name;

In this example, we first define a $month_names array and then define a $month_number variable , the value is 5, indicating the month of May. Next, we use the array_search() function to find the corresponding English month name in the $month_names array. If the corresponding month name is found in the array, return the name, otherwise return FALSE. In this example, since the value of $month_number is 5, the English month name "May" is returned.

In addition to using the array_search() function, we can also use the switch statement in PHP to convert month names. For example, we can use the following code to achieve the same function:

$month_number = 5;

switch ($month_number) {
    case 1:
        $month_name = 'January';
        break;
    case 2:
        $month_name = 'February';
        break;
    case 3:
        $month_name = 'March';
        break;
    case 4:
        $month_name = 'April';
        break;
    case 5:
        $month_name = 'May';
        break;
    case 6:
        $month_name = 'June';
        break;
    case 7:
        $month_name = 'July';
        break;
    case 8:
        $month_name = 'August';
        break;
    case 9:
        $month_name = 'September';
        break;
    case 10:
        $month_name = 'October';
        break;
    case 11:
        $month_name = 'November';
        break;
    case 12:
        $month_name = 'December';
        break;
    default:
        $month_name = '';
}

echo $month_name;

In this example, we use the switch statement to determine the corresponding English month name based on the value of $month_number. If the value of $month_number is 1, the value of the $month_name variable is set to "January", and so on. If there is no match, $month_name is set to the empty string.

To sum up, the process of converting month numbers into English month names is not complicated. You only need to define an array or use a switch statement to complete. This method can easily adapt to different languages ​​and national habits, making our code more flexible and versatile.
