How to get first and last day of the month with php

Using PHP’s mktime function , the last day of any given month can be expressed as the “0″ day of the next month , therefore :

$lastDayOftheMonthTimestamp = mktime(0,0,0,$currentMonthNumeric + 1,0,$currentFullYear);

Full example :

$currentTime         = time();
$dateTime            = getdate($currentTime);
$currentFullYear     = $dateTime["year"];
$currentMonthNumeric = $dateTime["mon"];
$firstDayOfTheMonth  = date('Y-m-d',mktime(0,0,0,$currentMonthNumeric,1,$currentFullYear));
$lastDayOfTheMonth   = date('Y-m-d',mktime(0,0,0,$currentMonthNumeric + 1,0,$currentFullYear));
 
   echo $firstDayOfTheMonth.PHP_EOL;
   echo $lastDayOfTheMonth .PHP_EOL;
