Need Help With PHP

[Thomas Rozanov]

During the process of learning PHP (which I have ) I came up with a couple of questions. Maybe some PHP experts could answer them.

1) You know how you put } or { after each statement I think. What's the rule for that? What do they do ? Which side do i put? { or } ?

2)How do I make a website url a variable? however I want one part of the website to be able to change (text-box) .

Like ex. $example= http://twitter.com/recessionwire but i want the recessionwire part to be changable when someone types in text box.

Thanks Guys!

if($condition){
// Do things
}

for the second you need a form somewhere, and in the appropriate module it's sent to

$url = 'http://www.twitter.com/';
$post = $this->post->input:
$twitter = $url.$post;

where your input field is named input.

Thanks A Lot Tom!

Could you explain number one more clearly please. I don't get it honestly.

And for # 2 http://mpmap02.flightgear.org/?pilots_filter_callsign=example

I need this site. So the example part is what i need to change. :

$url = 'http://mpmap02.flightgear.org/?pilots_filter_callsign=';
$post = $this->post->input:
$input = $url.$post;

The { and } (curly brackets) are used to contain statement blocks. You don't need to put one after every statement. They are used for blocks of statements which are grouped together. For example:

if ($x==1)
{
 statement 1;
 statement 2;
 statement 3;
}
statement 4;

In this example, if $x=1, then statements 1-3 will be executed, otherwise it will skip that block and continue with statement 4.

I kind of get it but still not confident :S
