How do i check if a directory exists and if it does then i go onto part c, then if it doesn't go to part b

E.g

if "/$username" exists //Part A

then

create /$username //Part B

else //Part C

Don't know if the statements are correct, fairly new to all this

My first attempt at writing something, i have the make directory code already, So that was only a basic outline

thanks, i looked on that site but didn't find it (must be my short attention span )

surely its easier to use is_dir() ? http://uk.php.net/manual/en/function.is-dir.php

Like this i think: -

Code:

If(file_exists($username)) //part A
{
mkdir($username); //part B
}
else
{
//part C
}

I think the file_exists() function can be used to check if directories exists aswell as files.

mkdir() is the function to create new directories.

Sorry, this is ages ago, but my code:

PHP Code:

<?

include("include/session.php");

if (file_exists($session->username))

{

mkdir($session->username);

echo "made";

}

else

{

echo "already made";

}

?>

always comes up as "already made" even if its not, what am i doing wrong?

if (file_exists($session->username))

mkdir($session->username);
echo "made";
}
//OTHERWISE
else
{
//DONT
echo "already made";

As you can see from the logic of the above, it seems to be wrong. it will only make a file if it exists. therefore, that is wrong. it should be

PHP Code:

<? 
include("include/session.php"); 
//note the ! before the file_exists
if(!file_exists($session->username)) 
{ 
mkdir($session->username); 
echo "made"; 
} 
else 
{ 
echo "already made"; 
} 
?>

Wow old thread ... i was loads of view on this one...
Yep your code just needed the ! symbal lol (hate when that happens)

Your code was saying: if file exists then create the dir.
Now with the code the Jay made he put the ! operator in to make it: if file does not exist then create the dir

Good Luck Mate,

It's amazing how simple some errors are. best thing to do is comment code as you go. makes reading logic easier and will be beneficial in the long run
