Php 无法上载原始CSV文件，但

当我手动重命名我的文件时，我可以将其上载。正常情况下，我不知道这行所回显的文件名（而不是块代码）有什么问题

我尝试了

str_replace

，但它在这里不起作用。有人告诉我js标签有问题，但我不知道它有什么问题，所以如果你们能帮我的话，我决定加载整个PHP

下面是关于没有使用设计模式的全部代码。。。 这

IF

是主要问题

IF（$filename[1]='csv'）{

代码

---

正如您在问题中所说的，问题出在if部分您需要将其设置为true才能继续，因此请尝试
if（1==1）
检查问题是否存在，如果是这样，您找到了解决方案，并尝试解决您需要的声明。
您能更详细地说明问题吗？您谈到手动重命名文件，这有什么帮助吗？不，不，当我更改文件名时，它的工作就是这样，例如，我的文件名是usal、 edu.ar-users.csv当我上传这个文件时，我得到了这一行警报（echo“alert（'uploaded'）；”；），但当我将它更改为123.csv或abc.csv或除原始名称以外的任何名称时，它就工作了。我将这一行（if（$filename[1]='csv'））更改为（if（1=1）我的文件已经准备好了，不需要更改名称。我不知道if block有什么问题！啊，示例文件名解释了它。好的，你看的是那行文件名的第二部分，因为数组索引是以零为底的。所以对于
123.csv
来说，第一部分是123，第二部分是csv。但是对于
edu.ar-users.csv第二部分是ar用户。您需要更改代码以查看
filename
的最后一个元素，而不是第二个元素。请查看
count（）
函数。
