[SOLVED] What do these things mean in php?

[jeger003]

hello,

i recently purchased a script and im trying to make sense of its code to hopefully change it around

 

im a newbie so i was hoping some can explain to me what these mean

 

elseif ($session_result->RecordCount() == 1)

what does the '->' mean?




$this->page_id = 22;
$this->get_text($db);
if ($this->classified_user_id)
{
$this->sql_query = "select * from ".$this->listings_table." where seller = ".$this->classified_user_id." and live = 1 order by date desc";


what does '$this->' mean?



echo $show->BOLDING." is classified BOLDING<Br>\n";

and finally what does this "$show->" mean and why would it need to echo is classified BOLDING?

 

 

i searched google php.net and a few other places and cant understand these things

 

i would appreciate links to source that would help or a small explanation

Take a look here.

That is a class.

 

 

In most languages they use a '.' but PHP uses a '->' instead.

[jscix]

-> and :: are simply ways to access a property or function of an object.

 

$this refers to the current object.

 

$show is an instance of an object.

 

$show->BOLDING, is either accessing a method, or property on '$this'

Awesome!

 

It gets really confusing when they look like variables but are not defined. Thanks so much for the help guys!

 

thanks for the link thorpe.........it helps A LOT when there are examples of how its used or can be used.
