I have a variable that has the value of rice, soon after receiving the value of rice, she gets the value ugliness. How do I call the past value of the function? Follow example below:
$arroz = "arroz";
echo $arroz; = arroz
$arroz = "feijao";
echo $arroz; = feijao
echo $arroz-valor-passado = "arroz";

This is not possible in a variable.
The solution I suggest is to have an array. So you accumulate values within it and use the count($array) - 1 to fetch the last value that was inserted into the array. And the previous values following the same logic. Something like this:
$comida = array();
$comida[] = "arroz";
echo $comida[count(comida) - 1]; // arroz
$comida[] = "feijão";
echo $comida[(count($comida) - 1)]; // feijão
echo $comida[count($comida) - 2]; // arroz

As I know PHP you can’t do that. Only if you keep the value passed in another variable or one array of past values.

I didn’t understand that line
echo $arroz-valor-passado = "arroz";. In addition, the use of a array might be the best choice like @Jorgeb said.– Papa Charlie
@Papacharlie when she does echo puts the expected result forward with the
= resultado– Jorge B.
@Jorgeb., I understood, could have used
//, but what I didn’t understand was$arroz-valor-passado. It is a new nonexistent variable?– Papa Charlie
@That’s Papacharlie. That’s how she wanted it to be...

@Jorgeb, I didn’t understand if it was a new var or a new var $rice (subtraction) past value - got confused. Could do something using
extract, depending on the use of var. It would be better to know the application.– Papa Charlie
