Python/PHP specific If you are asking specifically for Python and PHP scripts, SL4A probably is your best choice (though there are other Python supporting apps in the playstore, like e.g. QPython Lite). And if you want to automate things, you might want to take a look at the SL4A Script Launcher (in connection with TaskBomb task scheduler) as well. Shell Scripts But talking about "Linux" and "scripts in general", the first coming to my mind are Shell Scripts. These can be run directly from the command line using any terminal emulator (e.g. Android Terminal Emulator, Terminal IDE) -- or, if you prefer some "graphical help", using specific launcher apps like SH Script Runner, ScriptMe, or Script Manager.
