To convert the date-time format PHP provides strtotime() and date() function. We change the date format from one format to another. For example - we have stored date in MM-DD-YYYY format in a variable, and we want to change it to DD-MM-YYYY format.
We can achieve this conversion by using strtotime() and date() function. These are the built-in functions of PHP. The strtotime() first converts the date into the seconds, and then date() function is used to reconstruct the date in any format. Below some examples are given to convert the date format.
Change YYYY-MM-DD to DD-MM-YYYY
In the below example, we have date 2019-09-15 in YYYY-MM-DD format, and we will convert this to 15-09-2019 in DD-MM-YYYY format.
Output
New date format is: 15-09-2019 (DD-MM-YYYY)
Change YYYY-MM-DD to MM-DD-YYYY
In the below example, we have date 2019-02-26 in YYYY-MM-DD format, and we will convert this to 02-26-2019 (MM-DD-YYYY) format.
Output
New date format is: 02-26-2019 (MM-DD-YYYY)
Change DD-MM-YYYY to YYYY-MM-DD
In the below example, we have date 17-07-2012 in DD-MM-YYYY format, and we will convert this to 2012-07-17 (YYYY-MM-DD) format.
Output
New date format is: 2012-07-17 (YYYY-MM-DD)
Change DD-MM-YYYY to YYYY/MM/DD
Suppose we have date 17-07-2012 in DD-MM-YYYY format separated by dash (-) sign. We want to convert this to 2012/07/17 (YYYY/MM/DD) format, which will be separated by the slash (/). In the below example, DD-MM-YYYY format is converted to the YYYY-MM-DD format, and also dashes (-) will be replaced with slash (/) sign.
Output
date format is: 2012/07/17 (YYYY/MM/DD)
Change date time to another format
Here in the below example, we will convert the date format MM-DD-YYYY to YYYY-DD-MM format and 12 hours time clock to 24 hours time clock.
Output
New date time format is: 2019/13/06 17:35:00
