引用 php 中的常量:“这是一个 MY_CONSTANT"；
我想在 PHP 中使用一个常量，但我也想像变量一样将它放在双引号内.这有可能吗?
I want to use a constant in PHP, but I also want to put it inside double quotes like a variable. Is this at all possible?
define("TESTER", "World!");
echo "Hello, TESTER";
显然输出Hello, TESTER"，但我真正想要的是这样的:
obviously outputs "Hello, TESTER", but what I really want is something like:
$tester = "World!";
echo "Hello, $tester";
输出Hello, World!".
outputs "Hello, World!".
推荐答案
抱歉，这不是 PHP 中常量的工作方式.您可以将变量放在双引号和 heredocs 中，但不能放在常量中.
Sorry, that's not the way constants in PHP work. You can put variables in double quotes and heredocs but not constants.
