How to access an array and export variables?

Question

I have a code that receives the data via $_POST on a form as follows:

...
$certificate = $_POST['certificate'];
...

If you make a print_r($certificate) the result is as follows:

Array (
        ['cliente'] => White Martins Gases Industriais Ltda 
        ['entrega'] => 2017-04-11
        ['utilizacao'] => Oxigênio
        ['norma'] => White Martins - PR029
      )

The fields in the form are as follows:

<select type="select" class="form-control" name="certificate['cliente']" id="cliente">
<input type="date" class="form-control" name="certificate['entrega']" id="entrega"> 
<select type="select" class="form-control" name="certificate['utilizacao']" id="utilizacao">
<select type="select" class="form-control" name="certificate['norma']" id="norma">

How to assign the values of this array to 4 separate variables, type:

$cliente = ????;
$entrega = ????;
$utilizacao = ????;
$norma = ????;

I don’t know how to access the array.

Answer 1

One way to access the content would be to inform the name of the array,:

echo $certificate['cliente'];

Another way would also be using the Extract , that performs the function that Voce wants, of extracting the content and transforms into variables, thus:

 extract($certificate);
 echo $cliente;

A very simple example for your case, using array:

HTML

<form action="" method="post"><select type="select" class="form-control" name="certificate[]" id="cliente" value="cliente">
    <input type="text" class="form-control" name="certificate[entrega]" id="entrega" value="entrega"> 
    <input type="text" class="form-control" name="certificate[utilizacao]" value="utilizacao">
    <input type="submit">
</form>

Ai in PHP, Voce would take the data as follows:

<?php 
    $certificate=$_POST['certificate'];
    echo $certificate['entrega'];
?>

I hope I’ve helped

Answer 2

You can use the list(). However, as you do not use numeric Dexes you will need to use the array_values, as an example:

list($cliente, $entrega, $utilizacao, $norma) = array_values($_POST['certificate']);

Test it out here.

Then you can use $cliente, $entrega normally.

Answer 3

Have you tried that?

$cliente = $certificate['cliente'];
$entrega = $certificate['entrega'];
$utilizacao = $certificate['utilizacao'];
$norma = $certificate['norma'];
