魔术函数__call()函数? [英] Magic functions __call() for functions?
问题描述
php中的魔术函数__call()用于类中。有没有类似的魔术功能,但功能,而不是?像__autoload()是用于函数的。
例如,类似这样的
function __call($ name,$ arguments){
echoFunction $ name says {$ arguments [0]};
}
random_func(hello);
不,我不认为这样的魔术功能存在。
对此的一种解决方法是将您的函数放入静态类中,并添加 />)。只有PHP 5.3,恐怕): 对于PHP< 5.3,你可以做同样的事情,但你必须实例化一个对象并使用 The magic function __call() in php are used in classes. Are there any similar magic function but for functions instead? Like __autoload() is for functions. For example something like this
Nope, I don't think such a magic function exists. One workaround for this would be to put your functions into a static class, and add a For PHP < 5.3, you could do the same thing, but you would have to instantiate an object and use the

$ p $ class Func
{
/ ** PHP 5.3.0 * /
public static function __callStatic($ name,$ arguments)
{
//注意:$ name的值区分大小写。
echo调用静态方法'$ name'
。 implode(',',$ arguments)。 \\\
;
Func :: random_func(hello!);
__ call
魔术方法。
$ Func = new Func;
$ Func-> random_func(hello!);
function __call($name, $arguments) {
echo "Function $name says {$arguments[0]} ";
}
random_func("hello");
__callStatic
magic method to that class (> PHP 5.3 only, I'm afraid):class Func
{
/** As of PHP 5.3.0 */
public static function __callStatic($name, $arguments)
{
// Note: value of $name is case sensitive.
echo "Calling static method '$name' "
. implode(', ', $arguments). "\n";
}
}
Func::random_func("hello!");
__call
magic method.$Func = new Func;
$Func->random_func("hello!");
