I was working on a consol script for win32 and noticed a few things about it. On win32 it appears
that you can't re-open the input stream for reading, but rather you have to open it once, and
read from there on. Also, i don't know if this is a bug or what but it appears that fgets()
reads until the new line anyway. The number of characters returned is ok, but it will not halt
reading and return to the script. I don't know of a work around for this right now, but
i'll keep working on it.
This is some code to work around the close and re-open of stdin.
<?php
function read($length='255'){
if (!isset($GLOBALS['StdinPointer'])){
$GLOBALS['StdinPointer']=fopen("php://stdin","r");
}
$line=fgets($GLOBALS['StdinPointer'],$length);
return trim($line);
}
echo "Enter your name: ";
$name=read();
echo "Enter your age: ";
$age=read();
echo "Hi $name, Isn't it Great to be $age years old?";
@fclose($StdinPointer);
?>
