If a value is 0, NULL, false, or empty, the (bool) converts it into false, otherwise true.Even -1 converts to true.Cast to ArrayTo cast to array, use the (array) statement:Example $a = 5; // Integer $b = 5.34; // Float $c = "hello"; // String $d = true; // ...
$value = 'Foo'; $value['foo'] = 1; // error: Cannot assign offset 'foo' to string. 解包运算符操作对象是否可遍历 代码语言:javascript 代码运行次数:0 运行 AI代码解释 function foo(array $integers, string $str) { $foo = [ ...[1, 2, 3], ...$integers, ...$str // error: Only...
$privFunc('some value'); 以上例程会输出: string(10) "some value" 匿名类 现在支持通过 new class 来实例化一个匿名类,这可以用来替代一些“用后即焚”的完整类定义。 interface Logger { public function log(string $msg); } class Application { private $logger; public function getLogger(): Logger ...
