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：
$fruits = array("apple" => "red", "banana" => "yellow", "orange" => "orange");
foreach($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
$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。
