### Description
The following code:
```php
<?php
echo "January: " . (\DateTime::createFromFormat("Y/m",
"2022/01"))->format("Y-m-d") . PHP_EOL;
echo "February: " . (\DateTime::createFromFormat("Y/m",
"2022/02"))->format("Y-m-d") . PHP_EOL;
echo "April: " . (\DateTime::createFromFormat("Y/m",
"2022/04"))->format("Y-m-d");
```
Resulted in this output:
```
January: 2022-01-30
February: 2022-03-02
April: 2022-04-30
```
But I expected this output instead:
```
January: 2022-01-31
February: 2022-02-28
April: 2022-04-30
```
