Home Backend Development PHP Tutorial 怎样让<?=$row["id"] ?>输出一个数值啊

怎样让<?=$row["id"] ?>输出一个数值啊

Jun 23, 2016 pm 02:16 PM

我想把以前写的ASP程序转换成PHP程序,结果遇到一个*烦。就是:
ASP中


  

">
    )">编辑
 
   loop %>

则每个tr的id属性值分别为 fff1,fff2,fff3等

但改成PHP程序

    while($row=$result->fetch_assoc()){      ?> 

  ">
     )">编辑
 
   } ?>
则每个tr的id属性值都是 fff,fff,fff等,

我于是怀疑$row["id"] 的数据类型不是数值型,遂用$id=intval($row["id"])+0;去将其强制转换成数值型,但转换后结果为0啊
每个tr的id属性值都是 fff0,fff0,fff0等,

请问要怎么样使PHP中
每个tr的id属性值分别为 fff1,fff2,fff3等

你的环境开启短标记功能没有??

当然是开启的,
在别的程序中用=$row["id"] ?>输出都是没有任何问题的

那就是本身无值。。。

 不是啊,本身有值的,可以将值单独输出到页面中。

但是如果把值输出到警告框中,该值就会自动换行 ,如

alert("fff"+=$row["id"] ?>)
会输出  fff

        3
而alert("fff"+)
则输出 fff3,不会自动换行

alert("fff"+=$row["id"] ?>)
改成
alert("fff=$row[id] ?>")
试下

1.循?的??出???有  

)">编辑?一段有?有出??
2.如果有???下 echo $row["id"]; ?>替?成??是否可以
你?段代?看不出??所在
