4条解答一.php识别验证码
/这个验证码如何使用PHP自动识别并输出文字 在网上找到2个PHP识别程序 但是不会修改里面的代码其中一个显示 不正确
/ceshi/这个地址是我自己传到空间以后 测试的效果 上面输出的文字跟图片对不上
另外一个程序/phpcrash/直接显示错误下面我提供他们的下载地址/:///希望明白的人给于指导我个人感觉应该是程序需要修改设置
但是我看不是很明白里面的代码上面提供的地址是我自己空间的setImage(' /'); //引号内原值为 $valite->getHec();$ert =
$valite->run();//$ert = "1234";print_r($ert);echo '
'; //引号内 这个部分我自己修改过 原值为 ?>=================以上代码为

你直接发代码来看.
二.php来自注册验证码判断问题
现在验证的话大多数都是用ajax了。建议去看下这方面的书籍。
