I need urgent help, I couldn’t interpret this activity and I can’t fix the code

Question

My teacher gave me a PHP lesson and I swear I understood practically nothing, ask him for help is out of the question mainly because he is very ignorant and does not like when other students ask any kind of question. Here’s the text he sent:

All I could do was code, which didn’t go very far:

<?php


$dados = array('<p>nome: <br>', 'idade: <br>', 'salário: 1500<br>', '<p>ativo', '<p>não ativo');

$bonificacao = ($dados[2] / 100 * 10) + 1500;


foreach ($dados as $funcionario1) 
{
    $funcionario1[0] . 'Ferdinando';
    $funcionario1[1] . '25';
    echo $funcionario1;
}

foreach ($dados as $funcionario2) 
{
    $funcionario2[0] . 'Irineu';
    $funcionario2[1] . '40';
    echo $funcionario2;
}

foreach ($dados as $funcionario3) 
{
    $funcionario3[0] . 'Letícia';
    $funcionario3[1] . '19';
    echo $funcionario3;
}


?>

It is an activity to show that you have learned to manipulate an array (array) and make loops, and use variables.

$dados = array(
  array(
    'nome' => 'joao',
    'salario' => 100,
    'ativo' => false
  ),
  array(
    'nome' => 'maria',
    'salario' => 200,
    'ativo' => true
  ),
);

$bonificacao = 0.10;

foreach ($dados as $funcionario) {
  if (! $funcionario['ativo']) {
    continue;
  }
  $funcionario['salario'] += floatval($funcionario['salario']) * $bonificacao;

  echo $funcionario['nome'] . ' - ' . $funcionario['salario'];
}
