注意：将php升级到5.6版后，数组到字符串转换

I'm trying to display textarea and im getting an error at line 114. The notify is like this:

C:\xampp\htdocs\wp-content/plugins/options.php on line 114

My code is like this

 <?php
 function mistic_textarea($value,$attr){
 global $mistic_options,$wpdb;

            <li class="type-<?php echo ($value['type']);?>" id="container-<?php echo ($value['id']);?>">
                <fieldset class="title">
                    <div class="inner">
                        <label for="<?php echo ($value['id']); ?>"><?php echo ($value['name']); ?></label>
                        <?php if($value['desc']): ?><kbd><?php echo ($value['desc']); ?></kbd><?php endif;?>
                    </div>
                </fieldset>

                <fieldset class="data">
                    <div class="inner">
                        <textarea name="<?php echo ($value['id']); ?>" id="<?php echo ($value['id']); ?>" <?php echo ($attr); ?>><?php if(isset($mistic_options->$value['id'])): echo ($mistic_options->$value['id']); else: echo ($value['value']); endif;?></textarea>
                    </div>
                </fieldset>
                <div class="clear"></div>
            </li>
  }              
 ?>

And line 114 is :

 <textarea name="<?php echo ($value['id']); ?>" id="<?php echo ($value['id']); ?>" <?php echo ($attr); ?>><?php if(isset($up_options->$value['id'])): echo ($up_options->$value['id']); else: echo ($value['value']); endif;?></textarea>

Can anyone help me? I'm pretty new to PHP.

Thank for any kind of helps.
