I found a bug:
$date = new \DateTime('first day of this month');
$date->setDate(2001, 2, 3);
echo $date->format('Y-m-d');

This outputs: 2001-02-01
The day never changes.

Be warned, DateTime::setDate() does not check for invalid input.

Illustration:
<?php
$dt
= new DateTime();
$dt->setDate(2012, 11, 31); // returns DateTime object and not false although this date does not exist
echo $dt->format('Y-m-d'); // output: 2012-12-01
?>

No error was generated on entering a non existing date, php silently changed it.

Indjeto: You creating the datetime object with the first day of the month you are currently in when you initialize the object. Then you reset the date to the date you entered. Then you output, which is the day you entered because thats what you set it to. If you want to see the result you are assumed to be expecting you should not run the setDate() method.

Be carreful about this bug in php 5.6 and lower (fixed in php 7.0 and higher) :

<?php
$date
= new DateTime("first day of last month");
echo
$date->format('Y-m-d');
echo 
' => ' ;
$date->setDate(2013, 2, 3);
echo
$date->format('Y-m-d');
?>

Output <=5.6 : 2017-03-01 => 2013-02-01
Output >=7.0 : 2017-03-31 => 2013-02-03

Same goes for "Last day of last month", and the funny part, it will take the last day of the new month setted by setDate

Example with a Leap Year :
<?php
$date
= new DateTime("last day of last month");
echo
$date->format('Y-m-d');
echo 
' => ' ;
$date->setDate(2012, 2, 3);
echo
$date->format('Y-m-d');
?>

Output <=5.6 : 2017-03-31 => 2012-02-29
Output >=7.0 : 2017-03-31 => 2012-02-03
