怎样让<?=$row["id"] ?>输出一个数值啊
我想把以前写的ASP程序转换成PHP程序,结果遇到一个*烦。就是:
ASP中
loop %>
则每个tr的id属性值分别为 fff1,fff2,fff3等
但改成PHP程序
while($row=$result->fetch_assoc()){ ?>
} ?>
则每个tr的id属性值都是 fff,fff,fff等,
我于是怀疑$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
回复讨论(解决方案)
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
2.如果有???下 echo $row["id"]; ?>替?成??是否可以
你?段代?看不出??所在
