类封装验证图如何输出+JS
这是用类封装的一个验证图我的问题是如何在另外一个页面上调用它

PHP code


<?php
class ImageCode{
    private $randcode;                                            //随机字符
    private $randcodelength;                                    //随机字符长度
    private $imgWidth;                                            //随机字符宽度
    private $imgHeight;                                        //随机字符高度
    private $line = 5;                                                //干扰线
    private $code = array("q","w","e","r","t","y","u","i","o","p","a","s","d","f","g","h","j","k","l","z","x","c","v","b","n","m",
                            "Q","W","E","R","T","Y","U","I","O","P","A","S","D","F","G","H","J","K","L","Z","X","C","V","B","N","M",
                            "1","2","3","4","5","6","7","8","9","0");
    private $codelength;                                        //数组的长度

    private $image;                                            //图片
    private $background;                                        //背景
    private $foreground;                                        //前景

    function __construct(){
        $this->randcodelength = 5;
        $this->imgWidth = 80;
        $this->imgHeight = 20;
        $this->codelength = count($this->code)-1;                //获取数组长度当随机范围

        $this->createrandcode();
        $this->createimg();
        $this->createString();
        $this->drawline($this->line);
        $this->ending();

    }
    function createrandcode(){
        for($i=0;$i<$this->randcodelength;$i++){                //初始化验证码
            $this->randcode .= $this->code[rand(0,$this->codelength)];
        }
    }
    function createimg(){                                        //创建图片 前景 背景颜色
        $this->image = imagecreatetruecolor($this->imgWidth,$this->imgHeight);
        $this->background = imagecolorallocate($this->image,0,0,0);
        $this->foreground = imagecolorallocate($this->image,255,255,255);
    }
    function createString(){                                    //创建字符串
        imagestring($this->image,5,rand(5,35),0,$this->randcode,$this->foreground);
    }
    function drawline($some){
        for($i=0;$i<$some;$i++){
            imageline($this->image,rand(1,$this->imgWidth),rand(1,$this->imgHeight),rand(1,$this->imgWidth),rand(1,$this->imgHeight),$this->foreground);
        }
    }
    function ending(){
        ob_clean();                                    //抛弃缓存内容
        header("Content-type: image/jpeg");
        imagejpeg($this->image);
    }
}
?>

下面是输出页面

PHP code


<?php
include("ImageCode.php");
$imgcode = new ImageCode();
?>
