php-How to get date wise unique transaction number

0 votes

 was thinking of formatting it like this

TYYYYMMDDNNNN (2 character + 12 digits)

Where

T is a character (TR or SL) YYYY is the year (2018) MM is the month (03) DD is the day (30) N is a sequential number (0001, 0002, 0003, etc.)

I need auto increment N after getting the last data from the MySQL database.

Such as

20180330-0001, 20180330-0002, 20180330-0003.

20180331-0001, 20180331-0002.

20180401-0001, 20180401-0002, 20180401-0003 etc.

Can someone help me do this?
