PHP上传脚本出现500错误

所以我已经用头撞我的桌子好几天了，现在我想知道是什么导致了这个错误。每次我尝试发布一个文件映像时，它都会抛出一个错误：post 500内部服务器错误

不确定它到底意味着什么，以及如何着手解决它

你错过了一次机会；在队伍的尽头。使脚本无法编译的语法错误将导致服务器错误500

Apache错误日志中有答案。请检查一下，或者至少把你能看到的错误粘贴到这里。谷歌关于你在哪里可以找到它。真的。。。哈哈，也就是这样。谢谢不知道我是怎么一直错过的。再次感谢！

$upload_path = $path .$rnd.'_'.$_FILES[$input_file]['name']
