利用php-imagick制作动态显IP论坛图片签名

imagick是专门设计给php用的模块,虽说不如直接在命令行的效率高,但据说效率上比
gd2要快,并且可以做很多高级的操作,支持100+的图像类型,非常之强大,这里仅用它来显
示IP及来源,也就是往图片上“写字”,可以说是大材小用了。ip数据库请自行查找配置,只
要会点php应该就很容易改。如果不想显示ip的来源,只要把源码中的相应部分注释掉即可:
/*如果不显IP来源,注释开始
*/
……………………

/*如果不显IP来源,注释结束*/
picout
关于使用,这里也提一下吧,多数的论坛程序提供UBB的签名方式:[img]http://x.x.x.x/sign.php[/img]就行了!
 

//连接数据库,这里用的是discuz!的数据库类
//config.inc.php中存储了数据库的相关配置
/*如果不显IP来源,注释开始*/
include './config.inc.php';
include './db_mysql.class.php';
$db = new dbstuff;
$db->connect($dbhost, $dbuser, $dbpasswd, $dbname, 0, TRUE, $dbcharset);
//数据库的名字叫signpic,其中存了ip数据库
$db->select_db('signpic');
/*如果不显IP来源,注释结束*/
//字体文件的路径,我用的是微软雅黑
$font="./MSYHBD.TTF";
//用来当做背景的图片
$imgpath = 'chuanglian.png';
//图片上显示的文字
$word = '我就是显示IP而已,没有别的意思~';
//文字大小
$fontsize = 20;
//文字颜色,这个根据你的图片而定,不然看不到字了
$color = "black";
/*如果不显IP来源,注释开始*/
//获取用户的IP地址
$ip = $_SERVER['REMOTE_ADDR'];
//将IP地址转化为十进制,便于进入数据库查询
$iparray=explode('.',$ip);
$ipint=($iparray[0] * 256*256*256) + ($iparray[1]*256*256) + ($iparray[2]*256) +
$iparray[3];
//查数据库,得到IP的来源存在$from变量中
$sql = "select province, city, subcity from sp_ipaddress where $ipint>start and
$ipintfetch_first($sql);
/*如果不显IP来源,注释结束*/
if($row=="")
{
    $from = "来源未知";
}else
{
//这是查出来的三个项,省,城市,县——这个根据你的IP数据库的情况自己确定
    $from = $row['province'].'.'.$row['city'].'.'.$row['subcity'];
}
//读取用户是什么浏览器
$useragent = $_SERVER["HTTP_USER_AGENT"];
//只识别两种MSIE和FirFox
if(stripos($useragent,"firefox")){
    $browser="FirFox";
}elseif(stripos($useragent,"MSIE")){
    $browser="MSIE";
}
//生成显示文字,包含IP,来源和加的话
$text = "你的IP: $ip 浏览器: $browsern来自: $fromn".$word;
//读入背景图片
$image = new Imagick( $imgpath  );
$image->setImageFormat( "png" );
//生成画笔
$draw = new ImagickDraw();
//设置对齐方式,这里是居中对齐
$draw->setGravity( Imagick::GRAVITY_CENTER );
//设置字体
$draw->setFont( $font );
//设置字体大小
$draw->setFontSize( $fontsize );
//设置文字颜色
$textColor = new ImagickPixel( $color );
$draw->setFillColor( $textColor );
//往图片上写文字
$image->annotateImage( $draw, 0, 0, 0, $text );
//输出最后的结果
//header来表明MIME
header( "Content-Type: image/png" );
echo $image;
