Non-static method ..... should not be called statically

Question

I have recently done an update to PHP 5.4, and I get an error about static and non-static code.

This is the error:

PHP Strict Standards:  Non-static method VTimer::get()  should not be called statically in /home/jaco/public_html/include/function_smarty.php on line 371 

This is the line 371:

$timer  = VTimer::get($options['magic']); 

I hope somebody can help.

Answer 1

That means it should be called like:

$timer = (new VTimer)->get($options['magic']);

The difference between static and non-static is that the first one doesn't need instantiation so you can call the classname then append :: to it and call the method immediately. Like so:

ClassName::method(); 

and if the method is not static you need to initialize it like so:

$var = new ClassName(); $var->method(); 

However, in PHP 5.4 you can use this syntax instead as a shorthand:

(new ClassName)->method(); 

Answer 2

You can also change the method to be static like so:

class Handler {     public static function helloWorld() {         echo "Hello world!";     } }
