I have a class in the php and need to modify the value of private $key = "valor"; out of class.
How can I change the value of $key out of this class? The value I want to put in $key comes from a $_POST["name"].
class Webcmd {
private $key = "valor padrão a ser modificado";
function __construct(){}
...
}
I couldn’t find a way to define that value outside the class Webcmd and now I can’t either set a value that is being passed via POST.
How can I do that?

To change the state of an attribute of a class it is common to create access methods get for reading and set for writing, in this way it is possible to centralize some simple validations.
If this value does not need to be changed you can exchange the Setter for a parameter in the constructor.
<?php
class Webcmd {
private $key = "valor padrão a ser modificado";
function __construct() {
}
public function getKey() {
return $this->key;
}
public function setKey($key) {
$this->key = $key;
}
}
//chamada
$web = new Webcmd();
$web->setKey('Novo valor');
echo $web->getKey();
