Right here in the OS, I saw that I no longer need to use VAR, when declaring a variable in PHP, this was only until PHP4. Netbeans keeps giving error, if I don’t use, and use only the variable
How do I remove this?

To declare an attribute within a class in PHP, you declare the visibility, then the attribute.
Right
<?php
Class MinhaClasse{
public $atributo;
}
Wrong
Class MinhaClasse{
$atributo;
}
-
Have in case that declare then if it is a public variable, private or locked ne?
-
Within class yes

Thank you, Paulo!

I don’t know much about PHP, but I think you’re declaring class attributes, not variables. I don’t know if this makes a difference in language. By error, it seems that an access modifier is required before
$modelo;, nay?!– Renan Gomes
But from php5 you no longer need to use the var $nomedavariavel just use the $nomedavariavel
– Lucas de Carvalho
From what I understand of answer you accepted, requires an access modifier, says nothing about not using nothingness before the attribute name.
– Renan Gomes
That’s what Renan said, to remove the warning has two ways, use an IDE that does not warn :), which do not recommend, or fix the problem in the code.

I had it wrong.

Be careful variable and attribute/property are different things, if you notice no comment or answer cited variable.

Thanks rray, I’m getting a little confused in this entrance in POO, but I’m studying.

Just remember that learning Object-Oriented syntax doesn’t make you object-oriented (and there’s nothing wrong with that). If you program in structured paradigm, I recommend that you stay a while still programming in this paradigm, even using object-oriented syntax (for community reasons, not possible to explain here). The use cases where you will take advantage of the object-oriented paradigm will appear naturally. Don’t fall for the "real programmer does this..." or "that..." talk. Good luck to you!
