如何让php开关大小写检查类型?
How to make php switch case check for type?
问:
我希望用开关盒而不是 .===
==
<?php
$favcolor = "1";
switch ($favcolor) {
case 1:
echo "Your favorite color is red!";
break;
case "blue":
echo "Your favorite color is blue!";
break;
case "1":
echo "Your favorite color is green!";
break;
default:
echo "Your favorite color is neither red, blue, nor green!";
}
?>
这给了我:
Your favorite color is red!
但我希望它说绿色。这怎么可能?

从 https://secure.php.net/manual/en/control-structures.switch.php
请注意,开关/外壳确实比较松散。
你不能使用 switch 来实现这一点,请考虑使用 if - elseif - else 在这种情况下,例如:
if ( $favcolor === 1 )
echo "Your favorite color is red!";
elseif ( $favcolor === "blue" )
echo "Your favorite color is blue!";
elseif ( $favcolor === "1" )
echo "Your favorite color is green!";
else
echo "Your favorite color is neither red, blue, nor green!";
