PHP是一种松散类型的语言。当与大小写0匹配时，字符串与最接近的整数匹配。
假设我们有以下开关表达式-
switch ("match")现在，我们将匹配情况0-
case 0: echo " 0 with match"; break;
我们还将匹配非零情况-
case "match": echo "match successful"; break;
<!DOCTYPE html>
<html>
<body>
<?php
switch ("match") {
case 0:
echo " 0 with match";
break;
case "match":
echo "match successful";
break;
}
?>
</body>
</html>输出结果
0 with match
