unlink（/ home / goode / public_html / private / uploads / 405 /）：是一个目录，但是检查了file_exist

Question

In my form, I have more then 10 file uploads fields,

I have checked file exist though it is giving me error as below

my code is below,

 if (file_exists($filename))
                unlink($filename);

still it gives me error like below,

unlink(/home/goode/public_html/private/uploads/405/): Is a directory

Answer 1

You can change your code to:

if (is_file($filename)){
    unlink($filename);
}

The is_file function checks if it's a file. file_exists checks if it's a file OR directory. A bit confusing I will admit.
