Colon: vs PHP

Tenkte jeg skulle presentere noen små eksempler på hvordan Colon kode ser ut i forhold til PHP i da typiske PHP måter å gjøre ting på.

konkatinering av strenger

Colon

1. txtone: "Hello World"
2. txttwo: "1234"
3. txtone " " txttwo +2 out

PHP

1. $txt1="Hello World";
2. $txt2="1234";
3. echo $txt1 . " " . $txt2;

if

Colon

1. "Fri" "D" date = ?
2. "Hello!" out
3. "Have a nice weekend!" out
4. "See you on Monday!" out

PHP

1. $d=date("D");
2. if ($d=="Fri")
3. {
4. echo "Hello!<br />";
5. echo "Have a nice weekend!";
6. echo "See you on Monday!";
7. }

---

if/else/else

Colon

1. "D" date
2. "Fri" = ?
3. "Have a nice weekend!" out
4. "Sun" = ?
5. "Have a nice Sunday!" out
6. : "Have a nice day!" out

PHP

1. $d=date("D");
2. if ($d=="Fri")
3. echo "Have a nice weekend!";
4. elseif ($d=="Sun")
5. echo "Have a nice Sunday!";
6. else
7. echo "Have a nice day!";

PHP

1. switch ($x)
2. {
3. case 1:
4. echo "Number 1";
5. break;
6. case 2:
7. echo "Number 2";
8. break;

10. echo "Number 3";
11. break;
12. default:
