Actually, on a second look, while your repro script is buggy, the real issue is that underscores are
not valid scheme names.
Scheme names must contain ONLY [a-zA-Z0-9.+-] and no other characters.
This doesn't appear to be well documented, so I'll add a section to the manual.

There is a bug in your repro script:
if(in_array('diy_wrapper', $wrapper_list))
"diy" != "dir"
If you had the correct test there, you would see that your wrapper is already defined.

Description:
------------
<?php
class StreamDir
{
public $context = NULL;
public function dir_opendir(string $path, int $options)
{
return false;
}
}
$wrapper_list = stream_get_wrappers();
if(in_array('diy', $wrapper_list))
{
echo "stream wrapper already\n";
exit(0);
}
stream_wrapper_register("dir", "StreamDir");
$context = stream_context_create(['dir' => []]);
$dir = opendir('dir://Directory path', $context);
var_dump($dir);
Test script:
---------------
<?php
class StreamDir
{
public $context = NULL;
public function dir_opendir(string $path, int $options)
{
return false;
}
}
$wrapper_list = stream_get_wrappers();
if(in_array('diy_wrapper', $wrapper_list))
{
echo "stream wrapper already\n";
exit(0);
}
stream_wrapper_register("dir_wrapper", "StreamDir");
$context = stream_context_create(['dir_wrapper' => []]);
$dir = opendir('dir_wrapper://Directory path', $context);
var_dump($dir);
Expected result:
----------------
tips open directory failed
Actual result:
--------------
Warning: stream_wrapper_register(): Invalid protocol scheme specified. Unable to register wrapper
class StreamDir to dir_wrapper:// in PHP run script path
