编辑:try/catch 是否适用于 SOAP 异常,在使用 call_user_func 时触发?

} catch (SoapFault $fault) {
die($fault->faultstring)
}

This should work:
这应该有效:
call_user_func_array(array($this->object,'method'), array($arg1, $arg2));
The first argument is a callback type, containing an object reference and a method name.
第一个参数是一个回调类型,包含一个对象引用和一个方法名称。

Here's a hackish variant, might be useful to someone:
这是一个hackish变体,可能对某人有用:
$method_name_as_string = 'method_name';
$this->$method_name_as_string($arg1, $arg2);
This uses the PHP variable-variables. Ugly as hell, but not particularly uglier than the others...
这使用 PHP 变量变量。丑得要命,但也不是特别丑……
