CLI : shell can have colors, but PHP cannot output colors, displays ← left arrow instead

I have a shell that is color capable, but I cannot have a PHP script to output colors.

For instance:

$ echo -e "\e[32m Hello"

Outputs "Hello" in green as expected, but

$ php -r 'print "\e[32m Hello\n";'

prints the following in default color:

←[32m Hello

Any clue of what I should look into ?

It appears colored console output is not supposed to work reliably on windows as of yet (see PHP bug #72768 and the follow-up PR #2103). It worked on some combinations of windows/git shell/php, though.

So here's your options as far as I understand:

you may try to downgrade to working versions
try your luck with ansicon
use another terminal such as powershell or ConEmu
or wait for PHP 7.2 release where this issue is ought to be fixed
