Create a function full of elements and that returns two values in php

Question

How can I do a function with this code, since I will have to repeat it several times and the only things that change are the variables $a and $b. I need to use in my html the return of the two resulting variables ($title and $subtitle).

$situacao = 0;
$sql =  "SELECT * FROM `ed_painel` where (idaluno = '$id' or idaluno = '$id2') and a = '$a' and b ='$b' ;"; 
$result = $conn->query($sql); 
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
$situacao =  $row["situacao"];
$obs =  $row["obs"];
} }

if ($situacao > 3 and $situacao < 7) {
    $titulo = "AGUARDE";    }
else {
    $titulo = "PENDENTE";
    $subtitulo = '$obs';
   }

I know it’s not like that, but it would be something like that:

funcaoteste (1,2) //variáveis $a e $b
<h1> $titulo </h1> <br>
<h2> $subtitulo </h2> <br>


funcaoteste (7,3) //variáveis $a e $b
<h1> $titulo </h1> <br>
<h2> $subtitulo </h2> <br>


funcaoteste (4,1) //variáveis $a e $b
<h1> $titulo </h1> <br>
<h2> $subtitulo </h2> <br>

PHP cannot return multiple values directly (which is possible in Golang and Vlang, for example). You should use an "array" for this, it would be the easiest way, you can use the list() to simplify the process.

Therefore:

function funcaoteste(int $a, int $b) : array { 
    $situacao = 0;
    $sql = "SELECT * FROM `ed_painel` WHERE (idaluno = '$id' OR idaluno = '$id2') AND a = '$a' AND b ='$b' ;";
    $result = $conn->query($sql);
    if ($result->num_rows > 0) {
        while ($row = $result->fetch_assoc()) {
            $situacao = $row["situacao"];
            $obs = $row["obs"];
        }
    }

    if ($situacao > 3 && $situacao < 7) {
        return ["AGUARDE", ""];
    }

    return ["PENDENTE", $obs];
}

So you could use how:

[$titulo, $subtitulo] = funcaoteste(1,2)
<h1> $titulo </h1> <br>
<h2> $subtitulo </h2> <br>

This should only work on the latest versions of PHP. I’m ignoring other code problems.

You can also return something like ["titulo": $t, "subtitulo": $st] and use something like $resposta_do_funcaoteste["titulo"].
