If you want to prefill the prompt with something when using readline, this worked for me:
function readline_callback($ret)
{
global $prompt_answer, $prompt_finished;
$prompt_answer = $ret;
$prompt_finished = TRUE;
readline_callback_handler_remove();
}
readline_callback_handler_install('Enter some text> ',
'readline_callback');
$prefill = 'foobar';
for ($i = 0; $i < strlen($prefill); $i++)
{
readline_info('pending_input', substr($prefill, $i, 1));
readline_callback_read_char();
}
$prompt_finished = FALSE;
$prompt_answer = FALSE;
while (!$prompt_finished)
readline_callback_read_char();
echo 'You wrote: ' . $prompt_answer . "\n";
