图片和文字显示 [ 新手入门 ]

在model写了这个方法

public static function gettitle(){
  $models=self::model()->findAll(array('order'=>'id asc'));
  $ltitle=array();
  foreach ($models as $model)
  {
    if($model->image==NULL){
      $ltitle[$model->id][$model->title]=$model->title;
      $ltitle[$model->id][$model->title]=$model->url;
      //$ltitle[$model->id][$model->title]=$model->image;
    }else{
      $ltitle[$model->id][$model->image]=$model->url;
      $ltitle[$model->id][$model->image]=$model->title;
      $ltitle[$model->id][$model->image]=$model->image;
    }
  }
  return $ltitle;
}

然后显示

<?php
$lltitle=link::gettitle();     
foreach($lltitle as $id=>$title)
foreach ($title as $key=>$value)
echo CHtml::link($key,$value).' ' ;?>

这个只显示文字，如果我想有图片只输出图片不显示文字，怎么改
