You can use the date function to generate a date string of your desired format. As a second parameter, you can add a UNIX timestamp representing the date that you wish the string to hold.
The above example will print a date of the format year(4 digits)-month-day of the month. The full set of formatting options can be seen at: http://php.net/manual/en/function.date.php
echo date("Y-m-d h:i:s", time() - 86400);
The above example would print yesterday’s date in the format year (4 digits)-month-day of the month hours:minutes:seconds. It will print a date in the format 2017-02-02 09:44:43.
You can use the strtotime function to convert a date string to a unix timestamp: For example, strtotime(“2017-12-22”); would return a unix timestamp in the format 1513929600,
It is also possible to use strftime to get a string representing certain date in exchange for a UNIX timestamp.
echo strftime("day %A",time());
Strftime uses a different format to embed the date counterparts in the string and they can be viewed as usual in the PHP documentation: http://php.net/manual/en/function.strftime.php
You can use the time() function to get a UNIX timestamp of the current time in the server’s locale.
new Date() a detailed string ot the current date. +new Date() will get you a timestamp of the current date. You can also get the constituent parts of the current date by chaining methods.
new Date().getMonth() // 1 (the month will be between 0 and 11, not 1 to 12 new Date()..getDate() // 6 new Date().getFullYear() // 2017 new Date().getHours() // a number between 0 and 23 with the date’s hour new Date().getSeconds() // the seconds part of the date - from 0 to 59 new Date().getDay() // the day of the week - 0 for Sunday, 1 for Monday and so on until 6 for Saturday
You can actually pass a date to the date object and then get the constituent parts of that date and work with it: new Date(‘December 25, 2017 23:15:30’).getMonth() // 11
Also, you can change the date dynamically using the provided setters.
date = new Date() Mon Feb 06 2017 04:07:15 GMT+0200 (FLE Standard Time) date.setMonth(11) 1512526035261 date Wed Dec 06 2017 04:07:15 GMT+0200 (FLE Standard Time)
You can set the month (setMonth), the date (setDate), the hours (setHours), the year (setFullYear) with those analogously named methods.
