Usage Example
|
<?php
readline_add("Username"); /* $history[0] - if no input is given, it asks for it again */
readline_add("Shell","/bin/bash"); /* $history[1] - if no input is given it defaults to /bin/bash */
/* readline_list_history returns arrays, so handle the array how you wish... */
$history = readline_list_history();
print "Username: " . $history[0] . "n";
print "Shell Type: " . $history[1] . "n";
print cl(); /* we just do this to reset the colours so colours aren't broken when the script exits */
?>
