How would it be possible to access the $ foo attribute in the following inheritance example? I thought that by inheritance you could access properties and methods of the parent class but in this example I get an error.
<?php
class ClasePadre {
$foo= 5;
}
class ClaseHija extends ClasePadre {
public function miFuncion(){
echo $foo;
}
}
$nueva=new ClaseHija();
$nueva->miFuncion();
When you declare a variable or method in a class it must indicate the visibility of the variables or method; and to see it in the daughters class you have to use the $ this
class ClasePadre {
protected $foo = 5;
}
class ClaseHija extends ClasePadre {
public function miFuncion(){
echo $this->foo;
}
}
$nueva=new ClaseHija();
$nueva->miFuncion();
You must call $ foo in the correct context.
echo $this->foo
Also, you have to add the scope to the variable $ foo
protected $foo= 5;
