Get values from an array separately

Question

I have a page where shows me text fields to be filled (inputs), containing a "+" in it, in case the user needs more forms to fill in..

The input code of the form that receives the values entered by the user is thus:

Nome completo:<input name="nomeCompleto[]" id="nomeCompleto" type="text">

Taking into account that the "nomeCompleto[]" is referring to an array, so I made my PHP code receive the values through the $_POST, in such a way:

if(isset($_POST['nomeCompleto'])){
foreach($_POST["nomeCompleto"] as $nameC)
    {
        echo " => " . $nameC . "<BR>";

    }

Thus the above code returns me such values:

=> João
=> Fernando
=> Jacinto Ades Graça Vindo
=> Lucas
Array ( [0] => João [1] => Fernando [2] => Jacinto Ades Graça Vindo [3] => Lucas )   

The values with "=>" are the values that were typed in the inputs by the user, with php I made those values passed to an array, so they are sorted and identified in such a way. And with the "count" php, I can count how many items my array has, so it prints the value on the screen "4", why there are 4 values(from 0 to 3).

The complete code that returns me the values typed above was this way:

if(isset($_POST['nomeCompleto'])){
foreach($_POST["nomeCompleto"] as $nameC)
    {
        echo " => " . $nameC . "<BR>";

    }
        ?><br /><?php
        print_r(($_POST["nomeCompleto"]));// aqui ele me retorna os valores do array e suas respectivas posições( [0] => João [1] => Fernando...)
        ?><br /><?php

        $count = count($_POST["nomeCompleto"]); // aqui ele realiza a contagem do array via $_POST
        printf($count); // aqui ele me retorna o valor "4" que é a quantidade de 'itens' que compõe meu array.
        ?><br /><?php
        print_r($nameC); /*coloquei esse print_r pra ver o que ele me retornaria apenas com a variável $nameC.. e aqui ele me retorna apenas o ultimo valor do array, que seria "Lucas", cá esta um erro */
        ?><br /><?php

}

The first question is:

In "echo " => " . $nameC . "<BR>";" it returns me the values of the variable $nameC in such a way:

=> João
=> Fernando
=> Jacinto Ades Graça Vindo
=> Lucas

But why when I give one "print_r($nameC);" he returns only "Lucas"? and not all other names. (regardless if it is printf or print_r or echo)

The question is, how can I get such values separately within a loop? Following such logic in the case:

while($i=0;$i<$count;$i++){

printf($nameC[$i]);

}

Obs.: the variable "$nameC" is the variable I set up to be able to allocate the array values (in which case the array comes from a web page, using the $_POST i pulled the values and assign such to that variable

Note: It necessarily needs to be while because it governs a whole script repeat..

The problem with such a question is, in the logic of the loop I posted, it would return me something like:

1 = L
2 = u
3 = c
4 = a

And in case I didn’t really want him to read the array this way, why is it just reading the last item of the array, value by value (letter by letter in the case) and showing me on the screen at their respective positions.

In case I wanted it to be printed in such a way:

1 = João
2 = Fernando
3 = Jacinto....
4 = Lucas

Using the loop, what would be the logic for this to be accomplished?

Answer 1

In the form below, all your information will be displayed in the correct way:

<?php
$nomes = Array("João Paulo", "Maria Silva", "José Santos", "Pedro Matoso");
foreach($nomes as $nameC)
    {
        echo " => " . $nameC . "<BR>";

    }
        ?><br /><?php
        print_r($nomes);// Irá mostrar tudo o que estiver dentro do array
        ?><br /><?php

        $count = count($nomes); // Irá realizar a contagem através da variável definida
        printf($count); // Retornará a quantidade de posições do array.
        ?><br /><?php
        print_r(reset($nomes)); /*cAqui irá retornar a primeira posição do array devido ao uso do reset */
        ?><br /><?php
?>

The output of this code will be:

=> João Paulo
=> Maria Silva
=> José Santos
=> Pedro Matoso

Array ( [0] => João Paulo [1] => Maria Silva [2] => José Santos [3] => Pedro Matoso )
4
João Paulo

See a functional example in phpfiddle.

As we speak in the comments of this post, every interaction with the variable $nomeC should be done within the foreach, in this way:

<?php
$nomes = Array("João Paulo", "Maria Silva", "José Santos", "Pedro Matoso");
foreach($nomes as $nameC)
    {
        echo " => " . $nameC . "<BR>";
        echo ($nameC . "<br>");
        var_dump($nameC . "<br>");
        echo ("<hr>");

    }
?>

I noticed that you are trying to access variable position for the foreach:

printf($nameC[1]);

This variable, after exit pain foreach has only one position, which would be the last name on the list of array primary.

If you want to print a number before each name, use as below:

foreach($nomes as $nameC)
{
    echo  $contador . " => " . $nameC . "<BR>";
    echo ($nameC . "<br>");
    var_dump($nameC . "<br>");
    echo ("<hr>");
    $contador++;
}

The exit will be:

1 => João Paulo
João Paulo
string(15) "João Paulo
"
2 => Maria Silva
Maria Silva
string(15) "Maria Silva
"
3 => José Santos
José Santos
string(16) "José Santos
"
4 => Pedro Matoso
Pedro Matoso
string(16) "Pedro Matoso
"
