HomeBackend DevelopmentPHP TutorialPHP 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.
