replace singular variable assignment with an array loop and variable variables

I found this useful when passing in an array to a function, rather than assigning all the variables in the function manually from the array just loop through each item in the array and asign them that way.

Also this helps when adding additional items to the array later.

PHP

$fields_array = [
      "start" => 0,
      "max" => 50,
      "list_type" => "latest",
      "template_file" => "core-list-item-array.html",
      "order_by" => "field_name",
      "order_type" => "DEC"
    ];

/*
      $db_table_name = $this->db->escapeString($this->db_table_name);
      $start = $this->db->escapeString($fields_array['start']);
      $max = $this->db->escapeString($fields_array['max']);
      $list_type = $this->db->escapeString($fields_array['list_type']);
      $order_by = $this->db->escapeString($fields_array['order_by']);
      $order_type = $this->db->escapeString($fields_array['order_type']);
      $template_file = $this->db->escapeString($fields_array['template_file']);
      */
      // ^^ change to a loop -- this was the code before

      // assign all fields array to variable names. 
      foreach ($fields_array as $field_name => $field_value) {
    		//${$field_name} = $field_value;
    		// ${$field_name} = $this->db->escapeString($field_value);
			${$field_name} = $field_name;
			echo ${$field_name} . "<br>";
      }   
// and now this loop replaces it ^^^
