php上传自动生成缩略图及水印类


作者:网上收集    点击: 读取中...

开始第一步: (%$$#^64667*&%2)我型我塑www.5x54.com
   创建文件夹(%$$#^64667*&%2)我型我塑www.5x54.com,布局: (%$$#^64667*&%2)我型我塑www.5x54.com
      annex:附件(该目录下存放上传的原图片) (%$$#^64667*&%2)我型我塑www.5x54.com
        |— smallimg:存放缩略图片 (%$$#^64667*&%2)我型我塑www.5x54.com
        |— mark:存放水印图片 (%$$#^64667*&%2)我型我塑www.5x54.com
      include:存放类文件(%$$#^64667*&%2)我型我塑www.5x54.com,字体(本程序代码使用的是:04B_08__.TTF) (%$$#^64667*&%2)我型我塑www.5x54.com
        |— upfile.php:集成简单上传(%$$#^64667*&%2)我型我塑www.5x54.com,生成缩略图及水印的类文件信息 (%$$#^64667*&%2)我型我塑www.5x54.com
        |— 04B_08__.TTF:字体文件 (%$$#^64667*&%2)我型我塑www.5x54.com
      test.php:测试文件 (%$$#^64667*&%2)我型我塑www.5x54.com
(%$$#^64667*&%2)我型我塑www.5x54.com
进入第二步: (%$$#^64667*&%2)我型我塑www.5x54.com
   代码研究(%$$#^64667*&%2)我型我塑www.5x54.com,希望各位能好好看看(%$$#^64667*&%2)我型我塑www.5x54.com,小弟也是初学者(%$$#^64667*&%2)我型我塑www.5x54.com,同时也希望各位能提出宝贵意见(%$$#^64667*&%2)我型我塑www.5x54.com,小弟定会虚心领教的(写得不好不要拿鸡蛋砸偶噢) (%$$#^64667*&%2)我型我塑www.5x54.com
