PHP file upload .tmp file, finfo cannot read mime type

As shown in the picture

I am also messy,
PS:

in the picture above

<code>finfo_file($finof,basename($this->filePath))</code>

This is what I tested before

<code>finfo_file($finof,$this->filePath)</code>

Just try to print it, the problem is not that

finfo_fileYou need to pass in the path of the file, not the file name.

basename('C:WindowsTempphpA9C5.tmp') === 'phpA9C5.tmp'.

So, you should remove the basenamefunction
