replace string in the table - php

Question

I have to check a string and replace if the attribute is equal to "Destaque:" in the case where the attribute matches it fails to print the line, but I'm confused with the functions, can someone help me?
<?php
class Produto_Atributo
{
function __construct()
{
}
function produtoAtributo($codigo)
{
Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);
$banco_magento = Mage::getSingleton('core/resource')->getConnection('core_write');
$sql = "SELECT * FROM tw_produto_atributo where entity_id=" . $codigo;
$resultadoSql = $banco_magento->fetchAll($sql);
$count = 0;
foreach ($resultadoSql as $linha) {
$classe = '';
if ($count % 2 == 0) {
$classe = 'par';
}
else {
$classe = 'impar';
}
$_atributo = $this->recuperarAtributo($linha['attribute_id']);
$_optionText = $this->recuperarOptionid($_atributo, $linha['option_id']);
$descricao=$linha['ds_conteudo'] ;
$order = array("\n");
$replace = '<br />';
$newstr = str_replace($order, $replace, $descricao);
if (isset($linha['ds_conteudo']) && $linha['ds_conteudo'] != '') {
echo '<tr class="active '.$classe.'">
<td class="table-caracteristica-titulo" style="padding-left: 45px !important;padding-right: 45px !important; "> ' . ucwords( strtolower($_optionText)) . '</td>
<td class="table-caracteristica-descricao" style="padding-left: 45px !important;padding-right: 45px !important;"> ' . $newstr. '</td>
</tr>';
} else {
echo '<tr class="'.$classe.'">
<td class="table-caracteristica-titulo" style="padding-left: 45px !important;padding-right: 45px !important;">'if($_atributo->getFrontend_label()==!"Destaque:"){$_atributo->getFrontend_label();}else {'Loko'.$_atributo->getFrontend_label();} '</td>
<td class="table-caracteristica-descricao" style="padding-left: 45px !important;padding-right: 45px !important;"> ' . $_optionText . '</td>
</tr>';
}
$count = $count + 1;
}
}
function recuperarAtributo($atributo)
{
$cod = $atributo;
$attr = Mage::getModel('eav/entity_attribute')->getCollection()->addFieldToFilter('attribute_id', array('eq' => $cod))->getFirstItem();
return $attr;
}
function recuperarOptionid($atributo, $option_id)
{
return ($atributo->getSource()->getOptionText($option_id));
}
}

already got hahah
was very simple, here's the answer:
if (isset($linha['ds_conteudo']) && $linha['ds_conteudo'] != '') {
echo '<tr class="active '.$classe.'">
<td class="table-caracteristica-titulo" style="padding-left: 45px !important;padding-right: 45px !important; "> ' . ucwords( strtolower($_optionText)) . '</td>
<td class="table-caracteristica-descricao" style="padding-left: 45px !important;padding-right: 45px !important;"> ' . $newstr. '</td>
</tr>';
} else {
if($_atributo->getFrontend_label()<>"Destaque:"){
echo '<tr class="'.$classe.'">
<td class="table-caracteristica-titulo" style="padding-left: 45px !important;padding-right: 45px !important;">' . $_atributo->getFrontend_label() . '</td>
<td class="table-caracteristica-descricao" style="padding-left: 45px !important;padding-right: 45px !important;"> ' . $_optionText . '</td>
</tr>';
}
}
