PHP Date and Time
PHP has many built-in functions to work with dates and times. Here are some commonly used functions:
date() – This function returns the current date and time. You can format the date and time using parameters. For example
echo date("Y/m/d"); // Outputs: 2023/03/24
echo date("h:i:s A"); // Outputs: 02:34:45 PM
- strtotime() – This function converts a string to a Unix timestamp. For example:
$date = "2023-03-24";
echo strtotime($date); // Outputs: 1671763200
- time() – This function returns the current Unix timestamp. For example:
echo time(); // Outputs: 1648703673
- mktime() – This function returns the Unix timestamp for a specific date and time. For example:
echo mktime(0, 0, 0, 3, 24, 2023); // Outputs: 1671667200
- mktime() – This function returns the Unix timestamp for a specific date and time. For example:
echo mktime(0, 0, 0, 3, 24, 2023); // Outputs: 1671667200
- date_create() and date_format() – These functions allow you to create and format a date object. For example:
$date = date_create("2023-03-24");
echo date_format($date, "Y/m/d"); // Outputs: 2023/03/24
- date_diff() – This function calculates the difference between two dates. For example:
$date1 = date_create("2023-03-24");
$date2 = date_create("2023-04-01");
$diff = date_diff($date1, $date2);
echo $diff->format("%R%a days"); // Outputs: +8 days
These are just a few examples of the many date and time functions available in PHP. It is important to carefully read the documentation and use the appropriate function for your specific use case.
