Gone years without doing this....the flexible array of array / array of object filter

gistfile1.aw

<!-- In some controller, etc somewhere -->
<?php

// Say you find yourself with a big array of data
$messageList  = $email->getCompetitionMessages($competition);

// but you want to filter out anything from the admin
$messageList = array_filter($messageList,new Istart_Filter_ValueInObjectArrayFilter('fromEmail','admin@example.com'));

// Or, if < PHP 5.3
$messageList = array_filter($messageList, array(new Istart_Filter_ValueInObjectArrayFilter('fromEmail','admin@example.com'),'valueNotIn'));

// I'm using ZF, so I just put this in my DH_Filter_ValueInObjectArrayFilter
?>

// ValueInObjectArrayFilter.php :
<?php
class DH_Filter_ValueInObjectArrayFilter
{
    protected $propertyName;
    protected $value;
    public function __construct ($propertyName,$value)
    {
        $this->propertyName = $propertyName;
        $this->value = $value;
    }
    public function  valueNotIn($o)
    {
    	if(is_object($o)){
    		$propertyName = $this->propertyName;
    		return ( strtolower($o->$propertyName) != strtolower($this->value) );
    	} elseif (is_array($o)){
    		return ( strtolower($o[$this->propertyName]) != strtolower($this->value));
    	}
    	return true;
    }
    public function __invoke ($o)
    {
        return $this->valueNotIn($o);
    }
}
?>
