I get this error. Parse error: syntax error, unexpected T_DNUMBER in /hermes/bosweb26b/b865/ipg.synamegamescom/giveaway/versioncheck.php on line 5

You need to quote 1.0.2 as it is not a valid number (T_DNUMBER):

if ($vc == '1.0.2') {
  ...
}

I'd also encourage you to look at version_compare()

if ($vc == 1.0.2){

1.0.2 is not a valid number. Probably you need to compare it as a string '1.0.2' like:

if ($vc == '1.0.2'){

You should use: if ($vc == "1.0.2") { ... }

1.0.2 is not a valid number. You should treat it as a string instead:

if ($vc == '1.0.2') {...}
