Determine if variable is last in a while statement [+6rep]

[Jam-ez]

Your code looks more complicated!

So i have a few questions: what does the ".=" thing mean? I presume it means $string .= $string+"</p><hr />"; ?

And also, what does the last line mean? That is the most confusing part!

.=

$variable = 'hi';
echo $variable; // returns hi
$variable .= ", what's your name?";
echo $variable // returns hi, what's your name?
// All in all, when reading this in your browser, the return would be: hihi, what's your name? 
/////////////////////////////////////////////
// However, if we use the code below:
$variable = 'hi'; 
$variable .= ", what's your name?"; 
echo $variable // returns hi, what's your name?
// The end result is as expected hi, what's your name? 

As you can probably see, .= just adds to the existing variable.

As for the last line "substr_replace" simply replaces the text in a certain part of the string. (http://uk3.php.net/substr_replace)

Edit: Oh yeah, it means what you said in your post, pft what a pointless explanation.

Actually the end result will be an error due to missing ;'s

Ah, you win.

Good example, though.

Thanks a bunch, I don't post much round here (especially considering how long I've been on here...) so I try to make my helpful posts helpful.
