How to print_r $_POST array?

Question

I have following table.

Answer 1

<?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.

Answer 2

Came across this 'implode' recently.

May be useful to output arrays. http://in2.php.net/implode

echo 'Variables: ' . implode( ', ', $_POST);

Answer 3

$_POST is already an array. Try this:

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

Answer 4

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 5

Just:

foreach ( $_POST as $key => $value) {

  echo "<p>".$key."</p>";
  echo "<p>".$value."</p>";
  echo "<hr />";

} 

Answer 6

Because you have nested arrays, then I actually recommend a recursive approach:

function recurse_into_array( $in, $tabs = "" )
{
    foreach( $in as $key => $item )
    {
        echo $tabs . $key . ' => ';
        if( is_array( $item ) )
        {
            recurse_into_array( $item, $tabs . "\t" );
        }
        else
        {
            echo $tabs . "\t" . $key;
        }
    }
}

recurse_into_array( $_POST );
