Find last day of the month in PHP

Posted in LAMP, learning by ganu on February 28, 2007

Yday I was working with dates and got the situation to get the last day of the month so got this piece of code.

date(’Y-m-d’,strtotime(’-1 second’,strtotime(’+1 month’,strtotime(date(’m').’/01/’.date(’Y').’ 00:00:00′))));

And this piece of code will gv you the last day of the your corrent month.

    great! thx!

    to get the last month,
    date(‘Y-m-d’,strtotime(‘-1 second’,strtotime(date(‘m’).’/01/’.date(‘Y’).’ 00:00:00′)));

    the output will bre the last day of the month for last month.

    Hi

    I was thinking to write a complete function and then googled your this post. I cant believe you did it with one line.

    great work thank you.

    Just for the record -
    This here is a bit shorter and thus better readable:
    date(“Y-m-d”,mktime(0, 0, 0, (date(‘m’) + 1), 0, date(‘Y)))

    date(‘t’) is enough to get the last day of the month.

    You could combine all those strtotime functions:
    strtotime(‘+1 month -1 second ‘.date(‘Y’).’-’.date(‘m’).’-01′ );

    kumar is right to get the last day of the current month is just date(‘t’) you don’t need to use more function, remember keep it simple :)

    I agree this is much faster and readable

    date(“Y-m-t”); //t = number of days in the month

    cal_days_in_month() return days of month. Very handy, because format and year are parameters.

    Thank you.. thank you.. date(’t’) returns only date of the last month. But I was looking for code that return complete date for last day of the month(ex – 2000-01-31) and found it here – I used tobi’s code –
    date(“Y-m-d”,mktime(0, 0, 0, (date(‘m’) + 1), 0, date(‘Y’)))

    all this seems overly complex when ‘mktime(0,0,0,date(“m”) + 1, 0, date(“Y”)));’ does the same thing. Less function calls and slightly easier to read.

    mktime is very powerful, changing years or months if one value causes the them to roll over. date(“Y-m-d’,mktime(0,0,0, 2,32,2008)) will com out as 2008-03-03
