PHP Funktion um colorierte Ausgabe von Shellprogrammen zu erhalten

PHP function fetch colored shell program output

Not much to say about it. It uses the script command to emulate an existing TTY and passes through the output of the executed shell command. You can also use the script directly as shell command.

Hier gibt es nicht viel anzumerken. Die Funktion nutzt den script -Befehl um eine TTY zu emulieren und reicht die Ausgabe mit Escape-Zeichen an den Ausgabepuffer weiter. Das untenstehende Skript kann auch direkt unter der Kommandozeile ausgeführt werden.
