PHP Date & Time
In PHP, the date and time functions are used to work with dates and times. Some of the most commonly used functions are:
1) date(): The date() function is used to format a date and time.
The syntax of the function is as follows:
date('Y-m-d');
//Y = Current YEAR
//m = Current Month
//d = Current Date
2) time(): The time() function is used to get the current Unix timestamp. The Unix timestamp is the number of seconds since January 1, 1970 00:00:00 UTC.
For example, to get the current Unix timestamp, you would use the following code:
echo time();
3) strtotime(): The strtotime() function is used to convert a date string to a Unix timestamp.
The syntax of the function is as follows:
echo strtotime("2023-02-19");
DIfferent Type of Date Format:
<?php
// set the default timezone to use.
date_default_timezone_set('Asia/Kolkata');
// 2023-02-20 01:11:09 (the MySQL DATETIME format)
