!file_exists help

[TheSupportForum]

Hi guys

im trying to have a file created if not exist, so far i have

PHP Code:

$ourFileName = "$vbulletin->options['thefilename']";
 if (!file_exists($vbulletin->options['thefilename'] . '$ourFileName'))
{
$filename = '$ourFileName';
} 


i have also tried

PHP Code:

if (!file_exists($ourFileName)) {
$ourFileName = "$vbulletin->options['thefile']";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);
} 


they work in some ways but not 100%, im not even sure if its the correct format for vbulletin

i know this is not 100% correct but need the variable corrected
