thinkphp+iis6.0+win2003 验证码乱码
这个验证码非thinkphp自带的,该网站在本地电脑(win8.1)和其他win2003上正常显示,可传到服务器A就出现这错误
服务器A之前有使用过dz论坛,5.2.17 php版本,这要如何排错?请教,谢谢
回复讨论(解决方案)
在图片输出前加这句
header('content-type:image/gif');
在图片输出前加这句
header('content-type:image/gif');
谢谢,加上后还是同样的错误,是不是php.ini文件设置的原因?
这程序在别的服务器上都正常
echo base64_encode(file_get_contents('验证码程序的url'));

将header那句注释掉报错了没有?
echo base64_encode(file_get_contents('验证码程序的url'));

请去掉验证码程序的 BOM 头
<?php$s = base64_decode('77u/R0lGODdhMgAWAKEAAN//fWRkZEFodQAAACwAAAAAMgAWAAACloyPqSmy/4CctAIhMcXa+mp8X1c1kylaYZpyF8mqQUyjtHyXJbyL65Wz2IRD0OzUSCaRNg4vs9xMfp6mxvpE+o6jKwmbLVKoQOjGexabP2TtrqgUvrZVHmoYr9N7/PVLPcfG5VeG15GXFmV0JnL3pRhEBQgFBzmCE9Q1eYKZSYSoFCo6SlpqmtWZ4Rm4GuAAAcvwGgtRAAA7');echo substr($s, 3);
至于在别的机器上是正确的,并不能说明什么
你的这个程序在上传到 服务器A之前(后)用记事本做过了编辑
是不是php.ini设置有误?
已经开启extension=php_gd2.dll
图片中的错误我是直接访问index.php?m=Public&a=verify这样的地址出现的乱码,
本机访问这地址时,是显示图片验证码的
请去掉验证码程序的 BOM 头

刚用UE把index.php、Image.class.php、login.html、PublicAction.class.php都另存为UTF-8 无BOM,还是把这个错。
崩溃
老徐已经说了去掉BOM头 如果不了解什么是BOM头 百度一下
$s = base64_decode('77u/R0lGODdhMgAWAKEAAN//fWRkZEFodQAAACwAAAAAMgAWAAACloyPqSmy/4CctAIhMcXa+mp8X1c1kylaYZpyF8mqQUyjtHyXJbyL65Wz2IRD0OzUSCaRNg4vs9xMfp6mxvpE+o6jKwmbLVKoQOjGexabP2TtrqgUvrZVHmoYr9N7/PVLPcfG5VeG15GXFmV0JnL3pRhEBQgFBzmCE9Q1eYKZSYSoFCo6SlpqmtWZ4Rm4GuAAAcvwGgtRAAA7');echo bin2hex($s);
这个 efbbbf 就是 utf-8的 BOM 头
