        )       
)

回答1:

$array ;

foreach($array as $key => $value){
   foreach($value as $k => $val){
      echo $val . "<br> ;
   }
}

Output:

HUBZone Small Business  
Small Disadvantaged Business
Service-Disabled Veteran Small Businesses 

回答2:

print_r($array);

If given a string, integer or float, the value itself will be printed. If given an array, values will be presented in a format that shows keys and elements. Similar notation is used for objects.

回答3:

use foreach loops.

For your above array:

   foreach($arr as $a){
       foreach($a as $k=>$v){
           echo $v;
       }
    }
