长时间潜伏第一次海报,
我完成了把头发拉出来,所以我想我会吞下自己的骄傲并问专家, 我在这里阅读了超过20个类似的问题并尝试了所有修复解决方案,但我得到了相同的结果。我使用PHP供用户下载项目,但是我已经尝试过readfile和fopen但是每次下载都是损坏的,有时大小为0,其他正确(ish)大小,但总是损坏或损坏
有人可以看一下这段代码并告诉我它有什么问题,我已经搜过了很多次现在我可能只是错过了一些非常简单的东西,.....像往常一样
非常感谢任何帮助。
(如果需要,可以显示/loap.php的内容)
编辑:已解决 对于偶然发现这一点的人来说,只是一个快速更新,我设法让这个工作......我尝试了许多不同的某些命令,但似乎我错过了尝试" ob_clean( )"和" ob_end_flush()"用fopen(), ..它做了伎俩,因为我预计这是一个简单的解决方案感谢Twisty的帮助,你戳了我的灵感;)

对于偶然发现这一点的人来说,只是一个快速更新,我设法让这个工作......
我曾尝试过某些命令的许多不同变体, 但似乎我错过了使用fopen()的ob_clean()和ob_end_flush(),... 它做了伎俩,因为我预计这是一个简单的修复
感谢Twisty的帮助,你激发了我的灵感;)
更正后的工作代码已在OP中更新
答案 1 :(得分:0)
确保在最后一行readfile(FILE_NAME)
在我的情况下,我必须添加die();
或exit();
作为最后一行,因为MVC框架继续在readfile
之后呈现视图
