Noob Question about Variables

[Norman]

Hi, I've a noob question! :)In a .php file I've this:

<?php $txt = "Hello World!";$number = 5;?><?php $txt?>

But when browsered in my browser, nothing is print. What's wrong?

[Lulzim]

to print a variable you should use echo or print

<?phpecho $txt;?>

http://www.php.net/echo

-.-Ok, thanks! Is there some differences between print and echo?And another question. I've try to use this: echo $number--But it still print "5", and not "4". What's wrong?

[Lulzim]

The only differece I know is that print returns a true/false value and echo does not return anything.

echo $number--;

In this case variable $number is decremented after it is used.

$number = 5;echo $number--; //output is 5echo $number;	//output is 4$echo --$number;  //output is 3

Really thanks, Lulzim. Now I've understand.
