我试图显示动物和以年为单位的平均寿命，它不会显示生命。有什么帮助吗？
<?php
$animal = $_POST['animal'];
array(
$lifespans["Mouse"] => "4",
$lifespans["Queen Bee"] => "5",
$lifespans["Squirrel"] => "20",
$lifespans["Rattlesnake"] => "22",
$lifespans["Pheasant"] => "27",
$lifespans["Mallard Duck"] => "29",
$lifespans["Bear"] => "40",
$lifespans["Box Turtle"] => "123",
);
print("<p>The $animal has an average life space of $lifespans years.</p>");
？>
编辑：
用户有一个这些动物的下拉菜单，当他们选择一个并点击提交时，它将显示它们的寿命。
修复数组声明：
$lifespans = array(
"Mouse" => "4", // You could also do "Mouse" => 4, etc. as PHP will type-juggle
"Queen Bee" => "5",
"Squirrel" => "20",
"Rattlesnake" => "22",
"Pheasant" => "27",
"Mallard Duck" => "29",
"Bear" => "40",
"Box Turtle" => "123",
);
使用它来访问数组的特定元素：
print("<p>The $animal has an average life space of $lifespans[$animal] years.</p>");
不过，我是字符串连接的忠实粉丝：
print("<p>The " . $animal . " has an average life space of " . $lifespans[$animal] . " years.</p>");
