关联数组可以通过foreach循环遍历输出,也可以通过键值来访问特定的值。以下是一些例子:

  1. 使用foreach循环输出关联数组的所有值:
$fruits = array("apple" => "red", "banana" => "yellow", "orange" => "orange");  foreach($fruits as $key => $value) {     echo "The color of $key is $value <br>"; } 

输出结果:

The color of apple is red The color of banana is yellow The color of orange is orange 
  1. 使用键值来访问特定的值:
$fruits = array("apple" => "red", "banana" => "yellow", "orange" => "orange");  echo "The color of apple is " . $fruits["apple"]; 

输出结果:

The color of apple is red 

通过以上方法,可以方便地输出关联数组的值。
