I’m trying to make a file. php read an array, but I also want to assign an id to each value in Vector.

This is the html

<form method='GET'>
 <input type="hidden" name="idArray[]" value="1" />
 <input type="hidden" name="idArray[]" value="2" />
</form>

in php 

$id1 = $GET[''];

this is where I get lost, because I don’t know how to put the array inside GET, I searched some forums and tested the ways they were made, but I was unsuccessful

    Yes, it is possible! echo $_GET['idArray'][0]; you will need a for to list all values.

    Just do $ids = $_GET['idArray'];. Then just a for or foreach to show/run all.

The simplest way is to take it directly by the name of array:

<form method='GET'>
 <input type="hidden" name="idArray[]" value="1" />
 <input type="hidden" name="idArray[]" value="2" />
</form>

And in PHP

$ids = $_GET['idArray'];

Then just use the values as you see fit. For example:

foreach ( $ids as $id ) {
   echo $id . "<br>\n";
}

Or even as @rray commented:

$count = count( $ids );   // fora do for, senão o PHP reprocessa a cada iteração.
for($i = 0; $i < $count; ++$i) {
   echo $ids[$i] . "<br>\n";
}

On the form:

<form method='GET'>
   <?php for($i=1;i<count($array)+1;i++){?>
   <input type="hidden" name="tamanho" value="<?=count($array)?>" />
   <input type="hidden" name="array<?=$i?>" value="<?=$i?>" />
   <?php } ?>
</form>

No GET:

$tamanho = $_GET['tamanho'];

for($i=1;i<$tamanho+1;i++){
   echo $_GET['array'.$i];
}

That would be the idea, specify more the question and use POST.

    I get your idea, but I think if you put the "size" out of the "for" is better. The way it is, there will be an "size" entry for each item.
