With a question about foreach and incrementing another helper to perform an insert in the database, see:

When I send a form via post I get the following array as a result:

array (size=2)
  'quantidade' => 
    array (size=8)
      0 => string '10' (length=2)
      1 => string '11' (length=2)
      2 => string '15' (length=0)
      3 => string '22' (length=0)
      4 => string '10' (length=0)
      5 => string '9' (length=0)
      6 => string '0' (length=0)
      7 => string '35' (length=0)
  'produto' => 
    array (size=8)
      0 => string '11' (length=1)
      1 => string '18' (length=1)
      2 => string '19' (length=1)
      3 => string '21' (length=1)
      4 => string '22' (length=2)
      5 => string '25' (length=2)
      6 => string '29' (length=2)
      7 => string '22' (length=2)

As I'm using CodeIgniter to get the data from the Form, I'm using the following structure:

foreach ($this->input->post() as $chave => $valor) {
  //o array aux aqui
}

Some idea how to generate this result, taking the first value of each element and inserting it in an auxiliary array:

Type like this:

$array_aux[0] = array('quantidade' => 10, 'produto' => 11)
...
$array_aux[7] = array('quantidade' => 35, 'produto' => 22)

php array foreach codeigniter

Probably what you want is this:

array_combine( array $keys , array $values );

In your case:

$array_aux = array_combine( $array['quantidade'], $array ['produto'] );

If you are going to mount an array and make an insert via the CI's querybuilder, normally the key names should be the column names in the database, in which case you can use the array_map() function to combine the values. >

The anonymous function returns an array that will have the first (and remaining) item of $a1['quantidade'] and $a2['produto'] as its value.

$a1 = array('quantidade' => array(10,11,15,22,10,9,0,35));
$a2 =  array('produto' => array(11,18,19,21,22,25,29,22));

$r = array_map(function($q, $p){ return ['quantidade' => $q, 'produto' => $p] ;}, $a1['quantidade'], $a2['produto']); 

echo "<pre>";
print_r($r);

Output:

Array
(
    [0] => Array
        (
            [quantidade] => 10
            [produto] => 11
        )

    [1] => Array
        (
            [quantidade] => 11
            [produto] => 18
        )

    [2] => Array
        (
            [quantidade] => 15
            [produto] => 19
        )

    [3] => Array
        (
            [quantidade] => 22
            [produto] => 21
        )

    [4] => Array
        (
            [quantidade] => 10
            [produto] => 22
        )

    [5] => Array
        (
            [quantidade] => 9
            [produto] => 25
        )

    [6] => Array
        (
            [quantidade] => 0
            [produto] => 29
        )

    [7] => Array
        (
            [quantidade] => 35
            [produto] => 22
        )

What is it and how does it repeat in C #? Removing a specific space in a string

$arrayForm = array();

foreach($array['quantidade'] as $key => $val){
    $arrayForm[] = array(
                   'quantidade' => $val, 
                   'produto'    => $array['produtos'][$key]
    ); 
}

echo '<pre>';
print_r($arrayForm);
echo '</pre>';
