[英]Initialize class variable with function inside the class
我上课是这样的:
class Example{
private $a;
private $b;
function Example($user){
$this->a = $user;
$this->b = getsting(); //here is my problem
}
function getstring(){
return "string".$this->a; //here I have a class variable
}
}
我如何将价值返还给$b
?
class Example
{
private $a;
private $b;
function Example($user)
{
$this->userid=$user;
$this->b=$this->getstring(); //use $this-> before the method name
}
function getstring()
{
return "string";
}
}
在类内部,您需要使用$this->
来引用其他函数。
$this->b = $this->getstring();
PS这是getstring
,而不是getsting
。
