[SOLVED] mkdir question

[phpknight]

I have a question about the php mkdir() function.  The docs say it returns TRUE on SUCCESS and FALSE on FAILURE.

 

However, if you call this function on a directory that already exists, does it a) return true or false, and more importantly b) does it erase the current directory contents or leave it untouched?  I understand that is_dir would likely be called, too, but I need to know if files would be erased in case some call ever got through the cracks.

I Would Have Thought That I Would Just

Produce An Error (Return False) And Leave The Directory In Question Untouched

 

 

 

Maybe You Could Just Do A Simple Test?

 

 

 

ThanX,

That is what I am thinking too.  I am almost afraid to do a test in case I erase something important on the server.

I Would Do A Test Right Now

But Im Going To Go Offline After This Message

 

 

 

I Suggest That You Just Create A Test Directroy Named "testdir" And Put Some Blank TXT Files In It

And Then Execute The PHP Script Of Whats Described Above

 

 

 

 

 

Okay Bye,

I just did a test an it is turning '0' when a directory exists and also a warning 'Warning: mkdir() [function.mkdir]: File exists in blah blah'. Anyways just to be sure and surpress error messages u can use file_exists() to check if the directory exists or not, but in each case it will not delete a directory and all its files and create a blank one.

<?php
mkdir('test');
mkdir('test');
?>

 

Warning: mkdir() [function.mkdir]: File exists in /var/www/test.php on line 3
