   (PHP 4 )
   readline -- Reads a line

Description

   string readline ( [string prompt])

   This function returns a single string from the user. You may specify a
   string with which to prompt the user. The line returned has the ending
   newline removed. You must add this line to the history yourself using
   readline_add_history().

   Example 1. readline()
   <?php
   //get 3 commands from user
   for ($i=0; $i < 3; $i++) {
           $line = readline("Command: ");
           readline_add_history($line);
   }
   //dump history
   print_r(readline_list_history());
   //dump variables
   print_r(readline_info());
   ?>
