php syntax error on line 5

Question

    <?php

$vc=$_POST['versioncode'];

if ($vc == 1.0.2){

echo 1;  // for correct version code

} else {

echo 0; // for incorrect version code

}
?>

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

Answer 1

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()
