Re: Re: [PHP4BETA] array_walk: calling functions taking only ONE paramet && calling methods = not possible?

so we can stay at the point that using array_walk() within classes is not possible if one wants to call a function which only accepts one parameter, so I´m not able to manipulate some arrays inside a class catching (2) in the future would eliminate the need for (1), one can then create wrapper methods should I create a bug report for this? regards

    sorry only user-functions can be called by array_walk (and
    all other functions that accept a callback like this)

    so you need to create a functions in your script that then
    calles htmlspecialchars() and you should be fine.

// 2 does not work, as said array_walk($this->array,'this->wrapper'); }

    this is not supported right now - might get added somewhen in
    the future!

    tc

function wrapper(&$param1,$param2='') { return htmlspecialchars($param1); }} ?> --- snip ---

Hi, I tried to things with array_walk. 1) Calling a function like htmlspecialchars() with array_walk(), but it does not work: results in a wrong parameter count in array_walk(), I think array_walk() tries to use the numeric key as a second parameter for htmlspecialchars(), how do I avoid this. 2) After that I tried to avoid that calling a wrapper method in array_walk, I then had to notice that it´s not possible to call methods with array_walk();

    calling methods is currently not implemented for most
    functions that have php-callbacks.

Either array_walk is missing some functionality or I am missing something....

    any chance to send a short (10 lines) script that shows the
    behaviour?
