How can I print the cpf screen according to my code?
The code:
<?php
class valida {
protected $cpf;
public function cpf($cpf) {
if(is_numeric($cpf) and $cpf > 11) {
$this->cpf = $cpf;
return $cpf;
}
}
}
class manda extends valida {
function foo() {
return $this->cpf;
}
}
$cpf1 = $_GET['cpf'];
$p1 = new valida;
$p1->cpf($cpf1);
$sis = new manda;
echo $sis->foo();
What am I doing wrong?
$p1 has nothing to do with $sis , because they are different objects, although they have class hierarchy.
If you want the same CPF in $sis , you should assign it using cpf() ,
$sis = new manda;
$sis->cpf($cpf1);
echo $sis->foo();
It is clearer to understand class hierarchy if we think it serves for code economy in the child class,
class manda extends valida {
public function foo($cpf) {
// Aproveitando a implementação anterior de cpf().
$cpf = cpf(100000000000 + $cpf);
return $cpf;
}
}
$sis = new valida;
echo $sis->foo($cpf1);
EDIT: Change% from% to
public function cpf($cpf) {
if (is_numeric($cpf) && ceil(log10($cpf)) >= 11) {
this->$cpf = $cpf + 0;
return this->$cpf;
}
}
