How to call __construct() in a class by a variable

[RoBiNp]

This works normally:

$nameOfClass = 'SomeExistingClass'; // class name

$obj = new $nameOfClass();

echo $obj->someExistingFunction(); // display class

I want to use __construct() but changing someExistingFunction() to __construct() causes for some mysterious reason double mysql queries, double print_r() and double echo (function returns behave normally).

 

So how should I call __construct() ?

You usually shouldn't call it manually. It's called upon instantiation automatically.

[RoBiNp]

Yes, but where should I put the echo then? (I'm using return in __construct() )

[Daniel0]

You cannot return a value from the constructor.

 

You can use the __toString() magic method though. When you try to echo an object (or otherwise represent the object as a string), that function will be called.

Ah, thanks!
