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

}
?>

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") { ... }

I think you mean if ($vc == "1.0.2")... ?

yes, bad edit of mine, thanks. I added the brackets later and carried the " along.

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

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