There is an error reported in $name and I don’t know the reason.

$name I didn’t follow the example. What I wrote was $name=date('Y-m-d h:i:s').".".Tail variable

Then it prompted failed to open stream: Invalid argument in, if I remove the date, it will be fine. What did I do wrong?

代码没问题，应该是目标路径的问题，更改一下路径或者添加./试一试

Post the error message. rand(0,10).'.'.$lastimg; The code here is wrong. Change it to rand(0,10).$lastimg;

$lastimg actually equals jpg, so there is definitely no problem with the . in the middle. There is a problem just because the previous date is added.

What you are reporting is an error in the parameters of the date function

But what's wrong with date? There is no problem if I output this date ('Y-m-d H:i:s') alone~

Do important things need to be said three times? --! Then take a look at your entire code post. If this is correct, then it must be the mistake behind it.

date('Y-m-d H:i:s), pay attention to capitalization

I modified it as you said, but it still doesn't work. These are a few lines of code. Lastimg is the original one. There is no problem with this. $name=date('Y-m-d H:i:s').rand(0,10).'.'.$lastimg; if (is_uploaded_file($_FILES['file']['tmp_name'])) { if (move_uploaded_file($_FILES['file']['tmp_name'], $path .$name)) {

$name=date('Y-m-d H:i:s').rand(0,10).'.'.$lastimg; if (is_uploaded_file($_FILES['file']['tmp_name'])) { if (move_uploaded_file($_FILES['file']['tmp_name'], $path .$name)) {
