PHP __callStatic &方法名称字符无效
关于 PHP 中的 __callStatic() 的快速问题；
class Test{
public static function __callStatic($method, $arguments){
echo $method . PHP_EOL;
}
public function __call($method, $arguments){
echo $method . PHP_EOL;
}
}
$test = new Test();
$test->foo();
$test->{'hello-world'}();
Test::bar();
Test::{'goodbye-universe'}();
预期输出：
foo
hello-world
bar
goodbye-universe
实际输出：
foo
hello-world
bar
PHP Parse error: syntax error, unexpected '{', expecting T_STRING or T_VARIABLE or '$' in - on line 18
此语法是否不允许，也不能通过 __callStatic() 实现？
注意：试图摆脱无临时变量。以下内容将起作用：
$goodbyeUniverse = 'goodbye-universe';
Test::$goodbyeUniverse();
但我试图避免这种情况。
Quick question regarding __callStatic() in PHP;
class Test{
public static function __callStatic($method, $arguments){
echo $method . PHP_EOL;
}
public function __call($method, $arguments){
echo $method . PHP_EOL;
}
}
$test = new Test();
$test->foo();
$test->{'hello-world'}();
Test::bar();
Test::{'goodbye-universe'}();
Expected output:
foo
hello-world
bar
goodbye-universe
Actual output:
foo
hello-world
bar
PHP Parse error: syntax error, unexpected '{', expecting T_STRING or T_VARIABLE or '
Is this syntax not permissible, nor functionality achievable with __callStatic()?
Note: Trying to get away with no temporary variables. The following will work:
$goodbyeUniverse = 'goodbye-universe';
Test::$goodbyeUniverse();
But I'm trying to avoid that.

我认为 PHP 解析器目前无法处理这个问题。我现在无法证明这一点，但我认为这是一个类似的问题，例如函数调用后的数组取消引用问题（
callme()['arraykey']）。I don't think the PHP parser can handle that currently. I cannot prove it just now, but I think it's a similar issue like the array-dereferencing-issue after function calls (
callme()['arraykey']).您可以通过 call_user_func() 调用静态函数。
you could invoke a static function via call_user_func().
PHP 5.4 中已解决此问题
