DateTime::createFromFormat # separation doesn't allow a space

Description

The following code:

<?php
var_dump( DateTime::createFromFormat( '!d#M#Y H#i' , '07 Oct 2024 11:47' ) );

Resulted in this output:

bool(false)

But I expected this output instead:

object(DateTime)#1 (3) {
  ["date"]=>
  string(26) "2024-10-07 11:47:00.000000"
  ["timezone_type"]=>
  int(3)
  ["timezone"]=>
  string(13) "Europe/London"
}

From the PHP manual, the # should allow the following separation characters:

One of the following separation symbol: ;, :, /, ., ,, -, ( or )

This appears to include space, between . and -, but from the code above it doesn't parse the date string with a space. If I replace the format string with '!d M Y H#i ' it works as expected, so the : in the time is being handled by #, and the numeric parts fit the date format characters.

If I replace the spaces in the date string with - then it works as expected, so it's not anything else in the date string causing the issue.

var_dump( DateTime::createFromFormat( '!d#M#Y H#i' , '07-Oct-2024 11:47' ) );

object(DateTime)#1 (3) {
  ["date"]=>
  string(26) "2024-10-07 11:47:00.000000"
  ["timezone_type"]=>
  int(3)
  ["timezone"]=>
  string(13) "Europe/London"
}

PHP Version

PHP 8.3.9

Operating System

Windows Server 2016 ( IIS using PHP binaries from http://windows.php.net )

Start at the DateTime::createFromFormat entry point and reproduce the two format examples from the issue on PHP 8.3.9. The fix is complete when # accepts spaces as documented while continuing to parse the hyphenated and time-separator examples correctly.
