LXXXV. GNU Readline

A readline() f�ggv�nyek a GNU Readline k�nyvt�r haszn�lat�t teszik lehet�v� PHP-b�l. Ezek a f�ggv�nyek egy szerkeszthet� parancssort ny�jtanak. P�ld�ul ilyen a Bash, ami a kurzormozgat� gombok haszn�lat�val lehet�s�get ad karakterek besz�r�s�ra, �s a kor�bban kiadott parancsok visszak�r�s�re. Ezen k�nyvt�r interakt�v term�szet�b�l fakad�an kis hasznnal b�r Web alkalmaz�sok tervez�sekor, de hasznos lehet parancssorb�l fut� programok �r�sakor.

A GNU Readline projekt honlapja a c�men tal�lhat�. A honlapot Chet Ramey tartja fent, aki a Bash szerz�je.

`You'll probably need the --with-readline directive when configuring php to have the readline() functions available. If you've installed the readline libraries in /usr/local, add: --with-readline=/usr/local to your ./configure command.`

[Ed. note: you can use fopen("php://stdin", "w") to
achieve the same thing, works on both Windows and Unix)]



I wanted
to get console input in a PHP script running on windows, so I made a
little hack, which is so simple, it is clearly public domain.  What I did
was write a C++ program to get a line, then output it.  Then all that is
needed is to exec() that program and capture the output - readline() for
windows.  The C++ source is as follows:



#include
<iostream.h>

#include <string>

void main()

{

 
  string input;

    cin >> input;

    cout <<
input;

}



It works wonderfully for my purposes, since I love
the PHP language and want to have console input.

Here's an example simple readline-like way to input from command line on
windows - the single line is from 
the multiline is something I added...

<?
function read ()
{
	# 4092 max on win32 fopen

	$fp=fopen("php://stdin",
"r");
	$in=fgets($fp,4094);
	fclose($fp);

	# strip
newline
	(PHP_OS == "WINNT") ? ($read =
str_replace("\r\n", "", $in)) : ($read =
str_replace("\n", "", $in));

	return
$read;
}

function multilineread () {
	do {
		$in =
read();

		# test exit
		if ($in == ".") return
$read;

		# concat input
		(PHP_OS == "WINNT") ? ($read
= $read . ($read ? "\r\n" : "") . $in) : ($read =
$read . "\n" . $in);

	} while ($inp !=
".");

	return $read;
}

print("End input
with . on line by itself.\n");

print("What is your first
name?\n");
$first_name = multilineread();

print("What
is your last name?\n");
$last_name =
read();

print("\nHello, $first_name $last_name! Nice to meet
you! \n");
?>

`There is a simpler way to do a multiline read than above: function multiline() { while(($in = readline("")) != ".") $story .= ($PHP_OS == "WINNT") ? "\r\n".$in : "\n".$in; return $story; }`
