把GD库封装进类里面了,但不知道在那里出错了,
请有空滴大牛们帮忙看看,小弟感激不尽,谢谢
找了两天都没找到那里错了,图片还是显示不了,
如:
(先写了个表单biaodan.php)
nbsp;HTML>
(然后封装了个类vcode.class.php)
class Vcode{
private $width; //宽
private $height;//高
private $num; //数量
private $code;//验证码
private $img; //图像的资源
//构造方法, 三个参数
function __construct($width,$height,$num){
$this->width=$width;
$this->height=$height;
$this->num=$num;
$this->code=$this->gocode();//调用自己的方法
}
//获取字符的验证码, 用于保存在服务器中
function getcode(){
return $this->code;
}
//输出图像
function outimg(){
//创建背景 (颜色, 大小, 边框)
$this->createback();
//输出图像
$this->printimg();
}
//创建背景
private function createback(){
//创建资源
$this->img=imagecreatetruecolor($this->width,$htis->height);
//设置随机颜色
$bgcolor=imagecolorallocate($this->img,rand(225,255),rand(225,255),rand(225,255));
//设置背景填充
imagefill($this->img,0,0,$bgcolor);
//画边框
$bordercolor=imagecolorallocate($this->img,0,0,0);
imagerectangle($this->img,0,0,$this->width-1,$this->height-1,$bordercolor);
}
//画字
private function outstring(){
}
//设置干扰元素
private function grcode(){
}
//输出图像
private function printimg(){
if(imagetypes() & IMG_GIF){
header("Content-type:image/gif");
imagegif($this->img);
}else if(imagetypes() & IMG_JPG){
header("Content-type:image/jpeg");
imagejpeg($this->img);
}else if(imagetypes() & IMG_PNG){
header("Content-type:image/png");
imagepng($this->img);
}else{
die("No image support in this PHP server");
}
}
//生成验证码字符串
private function gocode(){
$codes = "3456789abcdefghijkmnpqrstuvwxyABCDEFGHIJKLMNPQRSTUVWXY";
$code= "";
for($i=0;$inum;$i++){
$code.=$codes{rand(0,strlen($codes)-1)};
}
return $code;
}
//用于自动销毁图像资源
function __destruct(){
imagedestroy($this->img);
}
}
(在调用类code.php)
//开启session
session_start();
include "vcode.class.php";
//构造方法
$vcode= new Vcode(80,25,4);
//将验证码放到服务器自己的空间保存一份
$_SESSION=$vcode->getcode();
//将验证码图片输出
$vcode->outimg();
回复讨论(解决方案)
你在浏览器地址栏输入code.php看看,看能不能生成验证码的图片
貌似也没看见你将数字写入画布上啊
写不好还是去网上找个能用的吧 晚上资源那么多
//创建资源 $this->img=imagecreatetruecolor($this->width,$htis->height);
//创建资源
$this->img=imagecreatetruecolor($this->width,$ htis->height);
