PHP Syntax

Hi all.

By now I should know the answer to what I am about to ask, but sadly not.

I fould the code below from a tutotial I was reading

In the code there is the use of "$qr->text", what exactly does this do? I can see it holds "test text" but why does it have "->" after the variable and not a = sign without the brackets.

If I wanted to populate $qr with $var how would this be done.

$var = "First test data";

$qr->text("Second test data");
echo "<p>UTF8 text</p>";
echo "<p><img src='".$qr->get_link()."' border='0'/></p>";

Read the PHP manual on classes.

It's PHP's way of accessing an object's properties (object-oriented PHP) or functions. Many languages use the period "." to access properties and functions, but PHP uses "->".

Hi Bonesnap/laserlight,

Many thanks for your replies.

I am currently reading the PHP manual on classes. I am learning all the time.

Thank you both.
