php how do i print out a whole array code example

Example 1: php print array

// raw array output
print_r($arr);

// the above well-formatted
echo '<pre>'; print_r($array); echo '</pre>';

// more details like datatype and length
var_dump($arr);

// output that PHP understands
var_export($arr);

// by foreach loop
foreach($arr as $key=>$value)
  echo $key, '=>', $value;	// $value must be convertible to string

Example 2: print array on php

foreach($results['data'] as $result) {
    echo $result['type'], '<br>';
}
