显示数组数组的随机值

Question

Below is a array generated by a query builder.

   $random_array =  Array ( [0] => Array ( [text] => A great time was had by all! ) 
            [1] => Array ( [text] => KILL SHOT ) 
            [2] => Array ( [text] => How is it possible) 
            [3] => Array ( [text] => http://www.youtube.com/watch?v=KwGOZpbxU9g ) 
            [4] => Array ( [text] => http://www.youtube.com/watch?v=KwGOZpbxU9g ) 
          )

Currently i am doing like this to print the random value

print_r(array_rand($random_array,1));

This is printing the array key as 3 or 1 etc(random from above array).I want to print the value of the key and not the key.

e.g I want to print the random value like this "http://www.youtube.com/watch?v=KwGOZpbxU9g" or "A great time was had by all!" instead of 3 or 1 which is printing now.

Is it possible to do this.

You will have one more line of code as shown below:

$array_key = array_rand($random_array,1); //get the key
print_r( $random_array[$array_key] );     //use the key to print value
