1、 数据库为 gtk_php

create table code_news
(
id int(9) not null default 0 auto_increment,
title char(255) not null,
author char(30) not null,
author_contact char(75) not null,
news text,
PRIMARY KEY (id),
UNIQUE ID (id)
);

2 、GTK 程序部分，用于图形化管理新闻 - admin.php

CODE:
[Copy to clipboard]
#!/usr/local/bin/php -q
<?

if(strtoupper(substr(PHP_OS, 0, 3)) == 'WIN')
dl('php_gtk.dll');
else
dl('php_gtk.so');


function destroy()
{
Gtk::main_quit();
}

function handle_select($clist,$row,$column,$event)
{
global $ret, $entry, $SELECTED_ID;
$id = $clist->get_text($row,0);
$SELECTED_ID = $id;
}

function add_record()
{
global $entry, $SELECTED_ID, $fields, $API_URL, $USERNAME, $PASSWORD;
while(list($f,$l) = each($fields))
{
$$f = $entry[$f]->get_text();
}
$news = $entry['news']->get_chars(0,$entry['news']->get_length());

$file = $API_URL.'?a=add&p='.$PASSWORD.'&u='.$USERNAME.
'&news[title]='.urlencode($title).'&news[author]='.urlencode($author).
'&news[author_contact]='.urlencode($author_contact).
'&news[news]='.urlencode($news);

$fp = fopen($file,'r');
if($fp)
{
$contents = trim(fread($fp,4096));
if(!eregi("^0:[A-Z]*",$contents))
{
clear_entries();
update_clist();
}
else
{
echo "n$contentsn";
}
}
reset($fields);
}

function delete_record()
{
global $entry, $SELECTED_ID, $USERNAME, $PASSWORD, $API_URL;
$file = $API_URL.'?u='.$USERNAME.'&p='.$PASSWORD.'&a=del&id='.$SELECTED_ID;
$fp = fopen($file,'r');
if($fp)
{
$contents = trim(fread($fp,4096));
if(!eregi("^0:[A-Z]*",$contents))
{
update_clist();
}
else
{
echo "n$contentsn";
}
}
}

function update_record()
{
global $entry, $SELECTED_ID;
echo "n************************* NOT IMPLEMENTED *************************n";
echo "nUPDATE RECORD : $SELECTED_IDn";
echo "n************************* NOT IMPLEMENTED *************************n";
}

function update_clist()
{
global $clist, $API_URL, $PASSWORD, $USERNAME, $ret;
// Grab everything from our API
$fp = fopen($API_URL.'?a=get&p='.$PASSWORD.'&u='.$USERNAME,'r');
if($fp)
{
$contents = fread($fp,4096);
if(!ereg("^0:[A-Z]*",$contents))
{
$clist->clear();
$ret = unserialize(trim($contents));
$clist->freeze();
while(list($id,$info) = each($ret))
{
// $info = $ret[$i];
$row = array($info['id'],$info['author'],$info['title']);
$clist->append($row);
}
$clist->thaw();
}
else
{
echo "nERROR: ".$contents."n";
}
}
}

function clear_entries()
{
global $entry;
$entry['title']->set_text('');
$entry['author']->set_text('');
$entry['author_contact']->set_text('');
// echo $entry['news']->get_text();
// $foo = $entry['news']->get_chars(0,$entry['news']->get_length());
// echo "n".$foo."n";
$entry['news']->backward_delete($entry['news']->get_length());
}

function delete_event()
{
return false;
}

$window = &new GtkWindow();
$window->connect('destroy','destroy');
$window->set_border_width(10);

$box = &new GtkVBox();
$window->add($box);
$box->show();

$fields = array(
title => 'Title: ',
author => 'Author: ',
author_contact => 'Author Contact: ');

// Set up our regular text fields
while(list($f,$l) = each($fields))
{
$vbox = &new GtkVBox();
$box->pack_start($vbox,false,false);
$vbox->show();
$vbox->set_border_width(3);

$hbox = &new GtkHBox();
$vbox->pack_start($hbox,false,false);
$hbox->show();

$label = &new GtkLabel("$l");
$label->set_usize(150,10);
$hbox->pack_start($label,false);
$label->show();

$entry[$f] = &new GtkEntry();

$hbox->pack_start($entry[$f],false);
$entry[$f]->show();
}

$vbox = &new GtkVBox();
$box->pack_start($vbox,false,false);
$vbox->show();
$vbox->set_border_width(3);

$label = &new GtkLabel('News:');
$vbox->pack_start($label);
$label->show();

$entry['news'] = &new GtkText();
$entry['news']->set_editable(TRUE);
$vbox->pack_start($entry['news']);
$entry['news']->show();

$buttons = array(
Add => 'add_record',
Delete => 'delete_record',
Update => 'update_record',
Clear => 'clear_entries',
Refresh => 'update_clist',
Quit => 'destroy');

$hbox = &new GtkHBox();
$hbox->set_border_width(3);

while(list($l,$f) = each($buttons))
{
$button = &new GtkButton($l);
$button->connect('clicked',$f);
$hbox->pack_start($button);
$button->show();
}

$scrolled_win = &new GtkScrolledWindow();
$scrolled_win->set_border_width(5);
$scrolled_win->set_policy(GTK_POLICY_AUTOMATIC, GTK_POLICY_AUTOMATIC);

$titles = array('ID','Author','Title');
$clist = &new GtkClist(sizeof($titles),$titles);
$scrolled_win->add($clist);
$clist->show();

$USERNAME = md5('joestump');
$PASSWORD = md5('phpgtk');
$API_URL = 'http://127.0.0.1/gtk/news_api/api.php';

// Grab everything from our API
update_clist();

$clist->set_usize(400,300);
$clist->connect('select-row','handle_select');

$auto_resize = array(0,1);
for($i = 0 ; $i < sizeof($auto_resize) ; ++$i)
$clist->set_column_auto_resize($auto_resize[$i],true);

$vbox->pack_start($scrolled_win);
$scrolled_win->show();

$window->show_all();
Gtk::main();

?>

3、 用于执行管理程序，向数据库加入数据的代码 api.php
<?

// Change username and password accordingly
$link = mysql_connect('192.168.192.47','root','')
or die('0:DB ERROR');

mysql_select_db('gtk_php',$link) or die('0:DB ERROR');

// Create a username and password to protect the
// API from outside people. THIS IS VERY IMPORTANT!
$USERNAME = md5('joestump');
$PASSWORD = md5('phpgtk');

switch($a)
{
case 'add':
// Make sure we are getting the 4 fields
// we want
if(sizeof($news) == 4)
{
// Check the given username and password against
// the ones we have - $p and $u are md5()'d in the
// GTK app and then sent along so no one can easily
// decrypt them.
if($p == $PASSWORD && $u == $USERNAME)
{
// extract($news);
while(list($key,$val) = each($news))
$$key = addslashes($val);

$sql = "INSERT INTO code_news
(title,author,author_contact,news)
VALUES
('$title','$author','$author_contact','$news')";

$r = mysql_query($sql);
if($r)
{
if(mysql_affected_rows($r))
echo '1:SUCCESS';
else
echo '0:FAILURE';
}
}
else
{
echo '0:BAD PASSWORD';
}
}
else
{
echo '0:BAD INFO ARRAY';
}
break;
case 'get':
if($p == $PASSWORD && $u == $USERNAME)
{
$sql = "SELECT * FROM code_news";
$r = mysql_query($sql);
if(@mysql_num_rows($r))
{
while($row = mysql_fetch_assoc($r))
$ret[$row['id']] = $row;
echo serialize($ret);
}
else
{
echo '0:NO RECORDS';
}
}
break;
case 'del':
if($id)
{
if($p == $PASSWORD && $u == $USERNAME)
{
$sql = "SELECT * FROM code_news WHERE id='$id'";
$r = mysql_query($sql);
if(@mysql_num_rows($r))
{
$sql = "DELETE FROM code_news WHERE id='$id'";
$r = mysql_query($sql);
include('http://'.$SERVER_NAME.$PHP_SELF.'?u='.$USERNAME.'&p='.$PASSWORD.'&a=get');
}
else
{
echo '0:ID NOT ON RECORD';
}
}
}
else
{
echo '0:NO ID GIVEN';
}
break;
default:
echo '0:UNRECOGNIZED ACCESS';
}

?>

4 、显示新闻 不用多说了- news.php  
<?

// Change username and password accordingly
$link = mysql_connect('192.168.192.47','root','')
or die('0:DB ERROR');

mysql_select_db('gtk_php',$link) or die('0:DB ERROR');

$sql = "SELECT * FROM code_news";
$r = mysql_query($sql);

if(@mysql_num_rows($r))
{
while($row = mysql_fetch_array($r))
{
extract($row);
echo '<b>'.$title.'</b>
';

if(ereg("@",$author_contact))
$href = 'mailto:'.$author_contact;
else
$href = $author_contact;

echo 'Posted By: <a href="'.$href.'">'.$author.'</a>
';
echo $news.'<hr>';
}
}
else
{
echo 'NO NEWS!';
}
