发布上传的文件名[关闭]

I want to output the filename. I also want to check the length of the filename. I have tried the following which didn't work.

echo $_POST[$_FILES['file']['name']];

echo (strlen($_POST[$_FILES['file']['name']]);

don't use $_POST for getting the files, simply use $_FILES to get the uploaded files as

echo $_FILES['file']['name'];

echo $_FILES['file']['tmp_name'];

To get the file size use

echo $_FILES['file']['size']

Solved.

 echo $_FILES['file']['name'][0];
