sapi_windows_vt100_support

(PHP 7 >= 7.2.0)

sapi_windows_vt100_support — Get or set VT100 support for the specified stream associated to an output buffer of a Windows console.

Description

bool sapi_windows_vt100_support ( resource $stream [, bool $enable ] )

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.

Avertissement

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.

Liste de paramètres

stream: The stream on which the function will operate.
enable: If specified, the VT100 feature will be enabled (if TRUE) or disabled (if FALSE).

Valeurs de retour

If enable is not specified: returns TRUE if the VT100 feature is enabled, FALSE otherwise.

If enable is specified: Cette fonction retourne TRUE en cas de succès ou FALSE si une erreur survient.

Exemples

Exemple #1 sapi_windows_vt100_support() default state

By default, STDOUT and STDERR have the VT100 feature enabled.

php -r "var_export(sapi_windows_vt100_support(STDOUT));echo ' ';var_export(sapi_windows_vt100_support(STDERR));"

L'exemple ci-dessus va afficher quelque chose de similaire à :

true true

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

L'exemple ci-dessus va afficher quelque chose de similaire à :

Exemple #2 sapi_windows_vt100_support() changing state

You won't be able to enable the VT100 feature of STDOUT or STDERR if the stream is redirected.

php -r "var_export(sapi_windows_vt100_support(STDOUT, true));echo ' ';var_export(sapi_windows_vt100_support(STDERR, true));" 2>NUL
