mkdir() tries to create file, even with validation - PHP

Question

im trying to create a file, and the method keep giving me this warning

Warning: mkdir(): File exists in

My code its working, but im tired of this warning now.
My code, currently is like this. Notice that $carFecha its a Date directory. Something like "2021-10-01".

$carFecha = "directory/to/a/date/"
if (!file_exists($carFecha)) { //If file doesnt exists
    echo $carFecha."</br>"; //This echo isnt there, but im printing it, to see what $carFecha is trying to create.
    mkdir($carFecha); //Create the file
}

The worst part, its that there are 4 of this codes, but only fails when im reaching this part.

In order to do this in a right way, you have to use is_dir() instead.

ìs_dir() - Tells whether the filename is a directory or not.

What i was trying to check, was a directory, not a file.

$carFecha = "directory/to/a/date/"
if (!is_dir($carFecha)) { //If DIRECTORY doesnt exists
    echo $carFecha."</br>";
    mkdir($carFecha); //Create the file
}
