c++ - How to pass objects to index array in PHP?

For example, I have an array

<code>$arr = array();</code>

How to make a string correspond to an (object/object reference)

Similar to std::map

For example, if you want to implement code similar to the following, how should you do it in PHP?

<code>class Obj {
    int var;
}

Obj my_obj = new Obj();
std::string str = "str";

std::map<std::string,Obj> s_o;
s_0.emplace( {str,my_obj} );        </code>

Thank you everyone

array('str' => new Obj())

PHP is weakly typed, any data can be passed to an array
