In this PHP statement: $admin->imgfolder = "img/"; what does the "->" mean?

Question

I know that $admin is a variable but I don't understand what the "->" means as it relates to "imgfolder"

Answer 1

When you see references such as => or -> it's simply referencing an object and it's property...

It's an array :-)

So instead of $row[2] your doing $row->nameofVariable

You could have MANY things stored in one object

$row->fname = 'Joe'
$row->lname = 'Hensen'
$row->gender = 'male'

THEN you would use:

echo $row->fname;
OR
echo $row->lname;
OR
echo $row->gender;

Make sense?

Remember that if your storing something into an array using this method you do not need a dollar sign infront of the variable name... if your using one at all....

Answer 2

It's pointing to the variable "$imgfolder" within the object that "$admin" contains. It means the same as "admin.imgfolder" in other C-like languages, but the period "." has a special purpose in PHP so an arrow is used instead.

Look up "PHP classes" for more about this.

Answer 3

It is used to send the variable to an object function or a data element.
