date - The first day of the current month in php using date_modify as DateTime object -

i can monday week with:

$monday = date_create()->modify('this monday'); 

i same ease 1st of month. how can achieve that?

thanks

requires php 5.3 work ("first day of" introduced in php 5.3). otherwise example above way it:

<?php     // first day of month     $d = new datetime('first day of month');     echo $d->format('js, f y');      // first day of specific month     $d = new datetime('2010-01-19');     $d->modify('first day of month');     echo $d->format('js, f y');      // alternatively...     echo date_create('2010-01-19')       ->modify('first day of month')       ->format('js, f y'); 

in php 5.4+ can this:

<?php     // first day of month     echo (new datetime('first day of month'))->format('js, f y');      echo (new datetime('2010-01-19'))       ->modify('first day of month')       ->format('js, f y'); 

if prefer concise way this, , have year , month in numerical values, can use date():

<?php     echo date('y-m-01'); // first day of month     echo date("$year-$month-01"); // first day of month chosen
