i want php date format in persian descriptioni mean f M d what is them

In Persian, the format characters for PHP date formatting are as follows:

• "f" represents the full month name in Persian. For example, "فروردین" for January.
• "M" represents the abbreviated month name in Persian. For example, "فرو" for January.
• "d" represents the day of the month with leading zeros if necessary. For example, "01" for the first day of the month.

Using these format characters, you can construct Persian date formats in PHP. For example, the format "f d, Y" will output the date like "فروردین 01, 2022"
