分享一款漂亮的验证码。
此代码来源于网络，haran只是进行了简单的改写与整合。

整合步骤
一、在你的项目/Lib中建立ORG目录，将TP框架/Extend/Library/ORG/Util/Image.class.php复制到刚刚建立的目录中。
二、打开刚刚复制过来的Image.class.php，将其中的buildImageVerify方法替换为以下代码 /**<br>
+----------------------------------------------------------<br>
* 生成图像验证码<br>
+----------------------------------------------------------<br>
* @static<br>
* @access public<br>
+----------------------------------------------------------<br>
* @param string $length 位数<br>
* @param string $mode 类型<br>
* @param string $type 图像格式<br>
* @param string $width 宽度<br>
* @param string $height 高度<br>
* @param string $size 字体大小<br>
+----------------------------------------------------------<br>
* @return string<br>
+----------------------------------------------------------<br>

static function buildImageVerify( $length=5, $mode='', $type='png', $width=300, $height=100, $size=40, $verifyName='verify') {<br>
<br>
import('ORG.Util.String');<br>
$fontPath = "./Public/elephant.ttf";<br>
$randval = String::randString($length, $mode);<br>
session($verifyName, md5($randval));<br>
<br>
$width = ($length * 10 + 10) > $width ? $length * 10 + 10 : $width;<br>
<br>
if ($type != 'gif' && function_exists('imagecreatetruecolor')) {<br>
$im = @imagecreatetruecolor($width, $height);<br>
} else {<br>
$im = @imagecreate($width, $height);<br>
}<br>
<br>
$r = Array(225, 255, 255, 223);<br>
$g = Array(225, 236, 237, 255);<br>
$b = Array(225, 236, 166, 125);<br>
$key = mt_rand(0, 3);<br>
<br>
$backColor = imagecolorallocate($im, $r[$key], $g[$key], $b[$key]); //背景色（随机）<br>
$borderColor = imagecolorallocate($im, 100, 100, 100); //边框色<br>
$pointColor = imagecolorallocate($im, mt_rand(0, 255), mt_rand(0, 255), mt_rand(0, 255)); //点颜色<br>
<br>
imagefilledrectangle($im, 0, 0, $width - 1, $height - 1, $backColor);<br>
<br>
@imagerectangle($im, 0, 0, $width - 1, $height - 1, $borderColor);<br>
$stringColor = imagecolorallocate($im, mt_rand(0, 200), mt_rand(0, 120), mt_rand(0, 120));<br>
// 干扰<br>
for ($i = 0; $i
$fontcolor = imagecolorallocate($im, mt_rand(0, 255), mt_rand(0, 255), mt_rand(0, 255));<br>
imagearc($im, mt_rand(-10, $width), mt_rand(-10, $height), mt_rand(30, 300), mt_rand(20, 200), 55, 44, $fontcolor);<br>
}<br>
for ($i = 0; $i
$fontcolor = imagecolorallocate($im, mt_rand(0, 255), mt_rand(0, 255), mt_rand(0, 255));<br>
imagesetpixel($im, mt_rand(0, $width), mt_rand(0, $height), $pointColor);<br>
}<br>
<br>
$x = $width/$length;<br>
for ($i = 0; $i
//imagestring($im, 5, $i * 10 + 5, mt_rand(1, 8), $randval{$i}, $stringColor);<br>
imagettftext($im, $size, rand(-30,30) ,$x*$i+5, $height/1.4, $stringColor, $fontPath,$randval{$i});<br>
}<br>
<br>
// @imagestring($im, 5, 5, 3, $randval, $stringColor);<br>
Image::output($im, $type);<br>
}三、下载elephant.ttf放置于项目目录/Public文件夹中

四、建立生成验证的方法并调用<?php <br />
<br>
Class PublicAction extends Action {<br>
<br>
Public function verify () {<br>
import('@.ORG.Image');<br>
Image::buildImageVerify();<br>
}<br>
}
