[SOLVED] if file dosen't exist? Then display message? Similar to (file_exists)

[A2xA]

I need to make it where if the file exists, then it won't overwrite it.  Also, if the file dosen't exist then it won't do anything but display an error message.

 

I've got the first part I just need to make it where if the file dosen't exist then it will just display an error message.

 

if (file_exists($dir)) {
    echo "The hub $dir exists already";
} else {

code..etc...

 

What else would I do to make both?

[stlewis]

if (file_exists($dir)) {

echo "The hub $dir exists already";

}

else 

   {

   echo "Your file doesn't exist, this is an error message"

}

 

 

You didn't provide any circumstances under which the file *would* be created, so barring any case where you'd want to, the above code would do what you described.
