sapi_windows_vt100_support — Get or set VT100 support for the specified stream associated to an output buffer of a Windows console.
$stream
[, bool $enable
] ) : bool
If enable is omitted, the function return TRUE if the stream stream has VT100 control codes enabled, FALSE otherwise.
If enable is specified, the function will try to enable or disable the VT100 features of the stream stream.
If the feature has been successfully enabled (or disabled), the function will return TRUE, or FALSE otherwise.
At startup, PHP tries to enable the VT100 feature of the STDOUT/STDERR streams. By the way, if those streams are redirected to a file, the VT100 features may not be enabled.
The function uses the ENABLE_VIRTUAL_TERMINAL_PROCESSING flag implemented in the Windows 10 API, so the VT100 feature may not be available on older Windows versions.
streamThe stream on which the function will operate.
enable
If specified, the VT100 feature will be enabled (if TRUE) or disabled (if FALSE).
If enable is not specified: returns TRUE if the VT100 feature is enabled, FALSE otherwise.
If enable is specified: Retorna TRUE em caso de sucesso ou FALSE em caso de falha.

By the way, if a stream is redirected, the VT100 feature will not be enabled:
php -r "var_export(sapi_windows_vt100_support(STDOUT));echo ' ';var_export(sapi_windows_vt100_support(STDERR));" 2>NUL
