Question

Screenshot of my array like this;

Array(
      [a] => val1 
      [b] => 
           Array(
                 [c]=>68 
          )
)

How can I get variable as;

a=val1
c=68

with php using loop?

Answer 1

$array = array('a' => 'val1', 'b' => array('c' => 68));
echo $array['a']; //val1
echo $array['b']['c']; //68

To just output all values of a multidimensional array:

function outputValue($array){
  foreach($array as $key => $value){
    if(is_array($value)){
      outputValue($value);
      continue;
    }
    echo "$key=$value" . PHP_EOL;
  }
}

The same can be accomplished using array_walk_recursive():

array_walk_recursive($array, function($value, $key){echo "$key=$value" . PHP_EOL;});
