PHP有条件>如何知道什么不匹配？

Question

if i have statement:

$a = 1;
$b = 2;
$c = 3;
if($a == 1 && $b == 2 && $c == 3)
{
  echo 'correct';
}
else
{
  echo 'what variable's weren't matched';
}

Is there any way of knowing what didn't watch instead of writing everything separately?

Cheers!

No. Your expression was turned into a boolean, so apart from checking the equality(s) again you cannot find out which triggered the "false".
