# readline

(PHP 4 >= 4.0.0)

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()
    //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());
