PHP equivalent to C++ Templates - php

Question

In C++, I can create template classes like this:
<template class l> class foo {
private:
l myVar;
foo::foo(l var) {
myVar = var
}
l getVar() {
return myVar
}
// etc...
}
Can I do something similar in PHP?
Reason I'm asking:
Let's say I have a class in PHP that conceptualizes a MySQL table:
class Table {
private $conn;
private $name;
function __construct($connection, $tablename) {
$this->conn = $connection;
$this->name = $tablename;
}
// etc..
}
I can make class functions that handle certain types of queries:
function GetAll() {
$sql = "SELECT * FROM " . $this->name;
$data = $this->conn->query($sql);
return $data;
}
Of course, this is just an example, but hopefully you get the picture.
What I'm looking to do is let's say I have a class called "Users". Before I return $data, I would like to put it in a User object. Of course, to be generic, I'd like to be able to put it into ANY class I like. Just like a C++ template.
Note: A PHP interface will not work for this because I'd need to instantiate the class, not just use a given set of functions.
Edit:
So, I found a workaround for MY problem.
However, I'd still like an answer to whether there is a PHP equivalent.

Answer 1

So, I figured out a work around, but I would still appreciate other answers. I would still like to know if there is a PHP equivalent. However, this is what I've got:
class Table {
private $conn;
private $name;
private filter; // a callback
function __construct($connection, $tablename, $callback) {
$this->conn = $connection;
$this->name = $tablename;
$this->filter = $callback;
}
// etc..
}
And then in GetAll:
function GetAll() {
$sql = "SELECT * FROM " . $this->name;
$data = $this->conn->query($sql);
$data = $this->filter($data);
return $data;
}
Then, I could pass a callback that filters the data how I want it.
I think that will work.
