Why can't PHP create a directory with 777 permissions?

Question

I\'m trying to create a directory on my server using PHP with the command:

mkdir(\"test\", 0777);

But it doesn\'t give full permissions, on

Answer 1

For those who tried

mkdir('path', 777);

and it did not work.

It is because, apparently, the 0 preceding the file mode is very important which tells chmod to interpret the passed number as an Octal instead of a decimal.
