An Odity

[trq]

Here is an oddity I just accidentally bumped into.

 

#!/usr/bin/php
<?php

class foo {

    public function bar() {
        echo "this is bar";
    }   

    public function callBar() {
        $this->bar();
    }   

}

class someother {
    public function callFooBar() {
        echo foo::callBar();
    }   
}

$so = new someother;
$so->callFooBar();

 

This means you can now do....

 

#!/usr/bin/php
<?php

class foo {

    public function bar() {
        echo "this is bar";
    }   

    public function callBar() {
        $this->bar();
    }   

}

class someother {
    public function callFooBar() {
        echo foo::callBar();
    }

    public function bar() {
        echo "this is someother bar";
    }   
}

$so = new someother;
$so->callFooBar();

 

Not sure it's useful, or just weird behaviour.

is that because you used $this and called foo as static context and it found the closest instance context to get "$this" value?

really interesting

That is indeed what is happening.

Whoah, that is tricky. IMO that shouldn't happen, but what do I know

 

On output this is what I see:

Strict Standards: Non-static method foo::callBar() should not be called statically, assuming $this from incompatible context in [..]foo.php on line 17

this is someother bar

Good, at least PHP tells you something is wrong
