PHP print array method in separate lines

We all know that php has two ways to print arrays.

$arr = array( "a"=>"orange", "b"=>"banana", "c"=>"apple");
echo "<pre class="brush:php;toolbar:false">";
print_r($arr);
var_dump($arr);
echo "

"; /**显示效果 Array ( [a] => orange [b] => banana [c] => apple ) array(3) { ["a"]=> string(6) "orange" ["b"]=> string(6) "banana" ["c"]=> string(5) "apple" } */

Like the print_r() function, the var_dump() function can also be used to print the data and structure of the array. However, the var_dump() function is more powerful than print_r(). It can print multiple variables at the same time and give the type information of the variables.
