简单的PHP函数调用不再工作[关闭]

Question

class blah{

    function a( x ){
    $variablename = b();
    ....
    }

    function b(){
    echo("why is this code (first line of function b) seemingly unreachable");
    ....
    }
}

it works fine when executed on a local server but not otherwise!?

Answer 1

You are missing dollar signs ($) on all variables.

I'm actually amazed it worked on local.
