动态循环并设置PHP类变量

Question

I have a class with several variables like:

class ABC
{
  $var1=0;
  $var2=0;
  ...
}

Instead of setting variables one by one like;

$ABC=new ABC();
$ABC->var1=1;
$ABC->var2=1;
...

How to loop through all class' (instance) variables and dynamically set them all to some value.

Answer 1

You could use get_object_vars to get the non static properties of the object, and then loop through that.

$object_vars = get_object_vars($ABC);

foreach ($object_vars as $name => $value) {
    $ABC->{$name} = $newVal;
}
