If file name exists...add 1 or add 2 to the end..

Hello,

1 more quick question.
Im saving an XML file on my server...it now removes white space and non file name chars.

If the file name already exists, it is overwriting.
How can i have it increment, if exists..

E.g.


Saving:
MyFileName

On Server Already
MyFileName

Saves It As
MyFileName1


Thanks!

you can use the function file_exists() to check if the file_exists()

 

$file = 'somename';

$int = 1;
$tmp = $file;

while (file_exists($tmp . '.xml'))
{
    $tmp = $file . $int;
    $int++;
}

$final_name = $tmp;
