示例代码:
class MyClass {
function echo_msg {
echo // now what...
}
function echo_from_inside {
$this->echo_msg()
}
}
result should be:
$my_instance = new MyClass();
$my_instance->echo_msg(); // I was called from OUTside
$my_instance->echo_from_inside(); // I was called from INside
用公共函数包装私有函数可能比检测函数的调用位置更容易。像这样:
class MyClass{
private function myob(){
//do something
}
public function echo_msg(){
$this->myob();
//do other stuff like set a flag since it was a public call
}
private function foo(){ //some other internal function
//do stuff and call myob
$this->myob();
}
}
$obj=new MyClass();
$obj->echo_msg();//get output
$obj->myob(); //throws error because method is private
您可以尝试获取方法的调用方:
$trace = debug_backtrace();
$caller = array_shift($trace);
echo 'called by '.$caller['function']
echo 'called by '.$caller['class']
这应该对你有用。
您可以添加这样的可选参数:
function echo_msg($ins=false) {
if($ins){/*called from inside*/}else{/*called from outside*/}
echo // now what...
}
最后离开。如果您从类内部调用它,请将其传递给true
,否则不传递任何内容!
