I'm working on a Mad Libs type assignment. I'm trying to have the heroname dictate the name of the frog my professor is making me use in the story, but for some reason, my if statement to rename the frog isn't working.

Every time I try to enter names for heroname (when it asks for "your name", it always ends up defaulting to Taylor and putting Henry as the frogname. How can I make this if-else statement work correctly to make the name be Henry only if Taylor or Jamie are entered for the heroname?

你在做分配而不是比较。更改if($heroname="Taylor"):为if($heroname=="Taylor"):（即=应该是==）。

（注意：您需要在所有四种情况下都解决这个问题，而不仅仅是第一个。）

您使用的是赋值运算符 (=) 而不是比较运算符 (==/===)

if($heroname="Taylor"):
$frogname="Henry";
elseif($heroname="taylor"):
$frogname="Henry";
elseif($heroname="Jamie"):
$frogname="Henry";
elseif($heroname="jamie"):
$frogname="Henry";
else: $frogname="Matthew";
endif;

至

if($heroname == "Taylor")
    $frogname = "Henry";
elseif($heroname == "taylor")
    $frogname = "Henry";
elseif($heroname == "Jamie")
    $frogname = "Henry";
elseif($heroname == "jamie")
    $frogname = "Henry";
else
    $frogname = "Matthew";

更好的是：

switch($heroname){
    case 'Taylor':
    case 'taylor':
    case 'Jamie':
    case 'jamie':
        $frogname = 'Henry';
        break;
    default:
        $frogname = 'Matthew';
}

这里有一些实用的东西。试试这种方式：

if (in_array(strtolower($heroname), array("taylor", "jamie"))) $frogname="Henry";
else $frogname=="Matthew";
