Question

I am trying to return the value of self calling function into variable that I will use later but get the following error Parse error: syntax error, unexpected T_FUNCTION, expecting ‘)’

any idea what am i doing wrong? Is it the way to do that? Here is the code:

$clientText = call_user_func(function(){
    if($lang == 'en'){
    return <<<END
    <p>hello world</p>  
END;
    } else {
             ...
        }
});

thank you.

update

Just found that my php version is 5.2. Is it still possible to do something like that?

Answer 1

Under php 5.2:

Nothing can stop you define the function and then call it.

    function getClientText($lang){
        if($lang == 'en'){
        return <<<END
        <p>hello world</p>  
    END;
        } else {
                 ...
            }
    }
   $clientText = getClientText($lang);

Or just do it:

  $clientText =   $lang == 'en' ?  '<p>hello world</p>' : $something_else
