With the following code: 

    $a=1;
    $b=1;
    echo $a."%".$b." maradéka: "." = ".$a % $b."<br>";
    echo $a."+".$b." összege: "." = ".$a + $b."<br>";

I get this output:

    1%1 maradéka: = 0
    2

As you can see, the + syntax is the same as the % but it doesn't echo the text before the operation. Maybe I'm too tired or i don't know, but i can't figure it out :D I've built dynamic web pages so far, but this one got me.

It is taking the numeric value of the first part and adding it to the second part. You'll want to group your math using parenthesis.

$a=1;
$b=1;
echo $a."%".$b." maradéka: "." = ".$a % $b."<br>";
echo $a."+".$b." összege: "." = ".($a + $b)."<br>";

  • To be clear, without the parentheses is the same as `echo (($a."+"....$a) + $b)."
    ";`, where the left hand side of the addition is a string beginning with `1`, and the right hand side is `int(1)`, hence the `2`.     – cmbuckley Nov 22 '16 at 23:43
  • +1 This is actually quite interesting how it processes the output. At first i did not realize that it could actually take the first value and add it to second value – Maciej Cygan Nov 22 '16 at 23:44
