How to print_r $_POST array?

Question

I have following table.

<form method="post" action="test.php">
  <input name="id[]" type="text" value="ID1" />
  <input name="value[]" type="text" value="Value1" />
  <hr />

  <input name="id[]" type="text" value="ID2" />
  <input name="value[]" type="text" value="Value2" />
  <hr />

  <input name="id[]" type="text" value="ID3" />
  <input name="value[]" type="text" value="Value3" />
  <hr />

  <input name="id[]" type="text" value="ID4" />
  <input name="value[]" type="text" value="Value4" />
  <hr />

  <input type="submit" />
</form>

And test.php file

<?php 

  $myarray = array( $_POST);
  foreach ($myarray as $key => $value)
  {
    echo "<p>".$key."</p>";
    echo "<p>".$value."</p>";
    echo "<hr />";
  }

?>

But it is only returning this: <p>0</p><p>Array</p><hr />

What I'm doing wrong?

Answer 1

The foreach loops work just fine, but you can also simply

print_r($_POST);

Or for pretty printing in a browser:

echo "<pre>";
print_r($_POST);
echo "</pre>";

Answer 2

<?php 

 foreach ($_POST as $key => $value) {
  echo '<p>'.$key.'</p>';
  foreach($value as $k => $v)
  {
  echo '<p>'.$k.'</p>';
  echo '<p>'.$v.'</p>';
  echo '<hr />';
  }

} 

 ?>

this will work, your first solution is trying to print array, because your value is an array.
