php remove forward slash from php URL

Question

I've tried everything I can find to remove the slashes that are being added to this:

$attribute = Mage::getSingleton('eav/config')->getAttribute('catalog_product', 'c2c_used_by_game');
if ($attribute->usesSource()) {
$options = $attribute->getSource()->getAllOptions(false);
echo ('<form method="post">');
echo ('<select onChange="window.location.href=this.value">');
foreach ($options as $option)

    {
        echo '<option value="'.Mage::getUrl('catalogsearch/advanced/result',array ('?c2c_used_by_game='=>$option['value'])).'">'.$option['label'].'</option>';
    }   
echo ('</select>');
echo ('</form>');
}

So that's outputing a select dropdown that creates a link such as on here .

I need one stinking slash removed after the equal sign so its c2c_used_by_game=561 and I just can't figure it out.

Answer 1

array ('?c2c_used_by_game='=>(str_replace('/','',$option['value'])))).

'">'.str_replace('/','',$option['label']).'</option>';

Answer 2

Use _query in the second parameter to construct query properly:

Mage::getUrl('catalogsearch/advanced/result', array('_query' => array ('c2c_used_by_game' => $option['value'])));

More info on getUrl function usage can be found on the Magento Wiki page .
