readline_callback_handler_install
(PHP 5 >= 5.1.0RC1)
readline_callback_handler_install -- Initializes the readline callback interface and terminal, prints the prompt and returns immediatelyOpis
bool readline_callback_handler_install ( string prompt, callback callback )
Sets up a readline callback interface then prints
prompt
and immediately returns.
Calling this function twice without removing the previous
callback interface will automatically and conveniently overwrite the old
interface.
The callback feature is useful when combined with stream_select() as it allows interleaving of IO and user input, unlike readline().
Parametry
prompt
The prompt message.
callback
The
callback
function takes one parameter; the user input returned.
