How to get the date of first day of previous month in php

How to get the date of  first day of previous month in php:

For getting the date of first day of previous month in php we have to use this code.


    public function getDate()
    {
        $curMonth = date('m', strtotime(date('Y-m-d')));
        $curYear = date('Y', strtotime(date('Y-m-d')));
        $occDate="$curYear-$curMonth-01";
        $forOdNextMonth= date('m', strtotime("-1 month", strtotime($occDate)));
        $forOdNextYear= date('Y', strtotime("-1 month", strtotime($occDate)));
        return "$forOdNextYear-$forOdNextMonth-01";
    }


Using this code we can get the desire result.

It will be helpful for getting the previous year even in December month which usually shows some problem for fetch.
