Note that this function is blocking if there is no character to read
If you don`t want to get blocked, you should use the trick with stream_select()

It also only reads one char per call,
So if something else in your script is blocking,
you`ve got a problem

It seems this function is not blocking anymore:

<?php

do {
 
readline_callback_read_char();
 
$str readline_info('line_buffer');
  echo 
'.';
} while (
strlen($str) < 10);

echo 
PHP_EOL $str PHP_EOL;

?>
