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

Question

I can get Monday this week with:

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

I would like to get with the same ease the 1st of this month. How can I achieve that?

Thanks

Answer 1

Ugly, (and doesn't use your method call above) but works:

echo 'First day of the month: ' . date('m/d/y h:i a',(strtotime('this month',strtotime(date('m/01/y')))));   

Answer 2

Requires PHP 5.3 to work ("first day of" is introduced in PHP 5.3). Otherwise the example above is the only way to do it:

<?php
    $d = new DateTime('2010-01-19');
    $d->modify('first day of this month');
    echo $d->format('jS, F Y');
?>

Answer 3

You can do it like this:

$firstday = date_create()->modify('first day January 2010');

Answer 4

In php 5.2 you can use:

<? $d = date_create();
print date_create($d->format('Y-m-1'))->format('Y-m-d') ?>
