Yes, before the Anniversary Update, console apps didn't require that flag.

But with Windows 10.0.14393 we need to set ENABLE_VIRTUAL_TERMINAL_PROCESSING.

Yes, you're right; that's not a Windows issue, but rather the ESC
seems to be substituted by the bug tracker.

However, I just tried your command line, and I already get the
colored output (Windows 10.0.10586 cmd.exe). :-/ (I haven't
noticed that before, because I usually run ansicon, where that
happens anyway).

In the Windows console it's represented by a left arrow as represented here: http://imgur.com/a/heYHm (at least with my codepage)

By the way, pasting that string in the browser caused that char to be suppressed, that's why I
wrote "?"

> (where ? is \033)

The ESC character is likely being suppressed by Windows.

Whoops, the link I mentioned is where I added my test code, the instructions I followed to compile
php.exe are at https://wiki.php.net/internals/windows/stepbystepbuild

I just recompiled php.exe using the instructions described at http://git.php.net/?p=php-src.git;a=blob;f=sapi/cli/php_cli.c;h=dc92045ae7402ad16566a9024453820a26c69da8;hb=HEAD#l1174
(using the version tagged php-7.0.9)

With the current code, the output of
Release_TS\php.exe -r "echo ""\033[101;93m TEST \033[0m\n"";"
is
?[101;93m TEST ?[0m
(where ? is \033)

Adding the SetConsoleMode-related stuff described in this #72768, I get
 TEST
(with red background and yellow foreground)

So, I can confirm that the approach described here is valid.

Just one note: I called SetConsoleMode only for STD_OUTPUT_HANDLE, but STDERR seems to follow
STDOUT:
Release_TS\php.exe -r "fwrite(STDERR, ""\033[101;93m TEST
\033[0m\n"");"
gives the same colorized output as writing to STDOUT.
