removing a value from an array

[gevans]

Hey guys,

 

This question isn't really how to do it, as I already have... but I didn't manage to do it the way I wanted to....

 

I have a 'breadcrumb' class that's main method gets passed an array of string. These strings are the different segments of the URI.

 

The whole process is fairly simple, but at the very beginning I check to see if 'home' is in the array, and if so remove it. I'm actually happy with the way I'm currently doing this, but was curious about 'array_filter()'.

 

If I user 'array_filer()' within a class what do I put in the callback place?

 

I thought about doing this (though it didn't really make sense);

 

<?php
class Breadcrumb extends Model {

    function Breadcrumb()
    {
        parent::Model();
    }

    function get(array $values)
    {
        var_dump($values);
        /*$i=0;
        $breadcrumb[$i]['title'] = 'home';
        $breadcrumb[$i]['safe_title'] = 'home';
        $i++;*/
        
        $values = array_filter($values, "$this->breadcrumb->_filter_home");
        
        var_dump($values);
        
        #return $breadcrumb;
    }
    
    function _filter_home($a)
    {
        return ($a === "home")? TRUE : FALSE;
    }
}

 

Was just wondering what you thought?
