readline — Reads a line
Reads a single line from the user. You must add this line to the history yourself using readline_add_history().
promptYou may specify a string with which to prompt the user.
Returns a single string from the user. The line returned has the ending
newline removed.
If there is no more data to read, then false is returned.

<?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());
?>Christian's code works well, but if you want to be able to hide the user input and not echo it to screen, you need to add -s to the read command. The code below is an expanded function that allows an optional prompt and optional hiding of the input:function read_password($prompt=null, $hide=false){ if($prompt) print $prompt; $s = ($hide) ? '-s' : ''; $f=popen("read $s; echo \$REPLY","r"); $input=fgets($f,100); pclose($f); if($hide) print "\n"; return $input;}If your CLI script accepts input from STDIN and you also want it to prompt for a password (e.g. as mysql client does), then readline() won't work for you. What you need to do is read from the terminal device as shown below.function readline_terminal($prompt = '') { $prompt && print $prompt; $terminal_device = '/dev/tty'; $h = fopen($terminal_device, 'r'); if ($h === false) { #throw new RuntimeException("Failed to open terminal device $terminal_device"); return false; # probably not running in a terminal. } $line = rtrim(fgets($h),"\r\n"); fclose($h); return $line;}$pass = readline_terminal('Password: ');In CGI mode be sure to call:ob_implicit_flush(true);at the top of your script if you want to be able to output data before and after the prompt.-- Tomas V.V.Coxa few observations....I use Cygwin PHP v7 and readline is available. The readline_list_history() function though is not defined.A prompt with escape sequences are sanitized, so use something like:<?php echo("\e[0m\e[34mPromt>\e[0m"); $inp = readline(' ');?>I have not fully documented it, but I see that sometimes strings beginning with punctuation characters do not make it into the history with readline_add_history(). They also sometimes clear the prompt string.Note that readline() will return boolean "false" when the user presses CTRL+D.
