Try this program in php to check if file exists :

<?PHP
 
$filename = 'file.csv'; 
IF (FILE_EXISTS($flnm)) 
{
PRINT "The file $flnm exists";
} 
ELSE 
{
PRINT "The file $flnm does not exist";
}
 
?>

bool file_exists ( string $filename )

This Checks whether a file or directory exists or not. On windows, use //computername/share/filename or \\computername\share\filename to check files on network shares.I'm thinking the quickest solution for this is to use the fopen() function... The file_exists() function doesn't support remote URL's, however, fopen() does.file() - Reads entire file into an array, is_writable() - Tells whether the filename is writable.

function file_nm($pth, $fme){
    if ($pos = strrpos($fme, '.')) {
           $nm = substr($fme, 0, $ps);
           $ext = substr($fme, $ps);
    } else {
           $nm = $fme;
    }
 
    $nwpth = $pth.'/'.$fme;
    $nwme = $fme;
    $count = 0;
    while (file_exists($nwpth)) {
           $nwname = $name .'_'. $count . $ext;
           $nwpth = $pth.'/'.$nwname;
           $count++;
     }
 
    return $nwme;
