PHP Parse $_POST Array?

Question

A server sends me a $_POST request in the following format:

POST {
  array1
  {
    info1,
    info2,
    info3
  },
  info4
}

So naturally

Answer 1

try

$_POST['array1'][0]
$_POST['array1'][1]
$_POST['array1'][2]

Answer 2

You can simply use a foreach loop on the $_POST

foreach($_POST["array1"] as $info)
{
    echo $info;
}

or you can access them by their index:

for($i = 0; $i<sizeof($_POST["array1"]); $i++)
{
    echo $_POST["array1"][$i];
}

Answer 3

Use index notation:

$_POST['array1'][0]
$_POST['array1'][1]
$_POST['array1'][2] 

If you need to iterate over a variable response:

for ($i = 0, $l = count($_POST['array1']); $i < $l; $i++) {
    doStuff($_POST['array1'][$i]);
}

This more or less takes this shape in plain PHP:

$post = array();
$post['info'] = '#';
$post['array1'] = array('info1', 'info2', 'info3');

So you can see it's really just an array in an array, with numeric indices.

Note, if it's an associative array, you need to use foreach():

foreach ($_POST['array1'] as $key => $val) {
    doStuff($key, $val);
}
