Misleading docblock of the file_get_info function

[4levels]

Hi,

the function file_get_info() has a docblock stating that it always returns an array, but it clearly does not as the first if statement will return FALSE instead of an array. This can easily lead to bugs as the code using the file_get_info() can easily assume this coming from the docblock comment.

The fix would be:

• either update the docblock to mention that the function can also return a boolean false @return array => @return array|false
• change the return to an empty array instead of boolean false

Please find the function doblock return type below.
