@H_404_1@var_dump：string(0)“”
@H_404_1@我正在尝试检查数组的一部分是否不为空,然后显示代码,但代码显示无论如何.
@H_404_1@我试过！is_null！空.我不确定哪个应该是正确的,或者我应该去：
if(sizeof($book [‘Booking’] [‘comments’])> 0) @H_404_1@码：
if(sizeof($book [‘Booking’] [‘comments’])> 0) @H_404_1@码：
<?PHP if (!empty($book['Booking']['comments'])) {?> <table width="100%" border="0"> <tbody> <tr> <td style="font-family:'Lucida Grande',sans-serif;font-size:12px;font-weight:normal;color:#666666;"> <?=$book['Booking']['comments']?> </td> </tr> </tbody> </table> <? } ?>@H_404_1@阵：
