Error message Strict standards: Non-static method should not be called statically in php

Your methods are missing the static keyword. Change

function getInstanceByName($name=''){

to

public static function getInstanceByName($name=''){

if you want to call them statically.

Note that static methods (and Singletons) are death to testability.

Also note that you are doing way too much work in the constructor, especially all that querying shouldn't be in there. All your constructor is supposed to do is set the object into a valid state. If you have to have data from outside the class to do that consider injecting it instead of pulling it. Also note that constructors cannot return anything. They will always return void so all these return false statements do nothing but end the construction.


I think this may answer your question.

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

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

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

Or, in PHP 5.4+, you can use this syntax:

(new ClassName)->method();

If scope resolution :: had to be used outside the class then the respective function or variable should be declared as static

class Foo { 
        //Static variable 
        public static $static_var = 'static variable'; 
        //Static function 
        static function staticValue() { return 'static function'; } 

        //function 
        function Value() { return 'Object'; } 
} 



 echo Foo::$static_var . "<br/>"; echo Foo::staticValue(). "<br/>"; $foo = new Foo(); echo $foo->Value();

Try this:

$r = Page()->getInstanceByName($page);

It worked for me in a similar case.


use className->function(); instead className::function() ;
