I have different classes in which I have different properties. Now I want to instantiate these classes at runtime. Please have a look on my Example. Thank you for your help.
class costumers
{
$ Name;
...
}
class users
{
$ Username;
...
}
class db_helper{
...
public function select (object $table, $columns, $limit, $offset) {
// Instance the object like
$out = new typeof ($table);
}
}
I think what you're trying to do is to create a new instance of the same class as the $table object? Then it's simple with get_class() function:
class db_helper{
...
public function select (object $table, $columns, $limit, $offset) {
// Instance the object like
$class = get_class($table);
$anotherTable = new $class();
// ...
}
}
Perhaps you may want to take a look at this commented Code. It may give you some hints....
<?php
class costumers {
protected $Name;
//...
}
class users {
protected $Username;
//...
}
class db_helper {
//...
// NOTICE THAT THERE IS NO TYPE-HINT HERE...
// BAD PRACTICE! BUT THIS IS TO DEMONSTRATE
// THE POSSIBILITIES AVAILABLE TO YOU IN THIS CASE...
public function select($table, $columns, $limit, $offset) {
// INITIALIZE $out TO NULL TILL YOU KNOW MORE...
$out = null;
if(is_object($table)){
// IF $table IS AN OBJECT....
// JUST START USING IT WITHOUT INSTANTIATION:
$out = $table;
}else{
if(class_exists($table)){
// Instance the object like
$out = new $table;
}
}
}
// START USING THE OBJECT: $out
}
$className = get_class($table);
$out = new $className();
If you want to do something more, please read about reflection.
new typeof()? Which of the 2 classes (costumersandusers) are you intent of instantiating within the select function? And, where is this select function declared?$tableis already anObject.... not aClassand therefore you can directly start using$tablewithout instantiating it again.....
