从mysql中取一个有内容的字段打印出来,却报错了解决办法

echo mysql quot

从mysql中取一个有内容的字段打印出来,却报错了
打算从MYsql里面取一个字段出来试试nl2br 函数的效果,可是报错了。
写法(目前,数据库中仅一条记录):

PHP code
<!--

-->$result = mysql_query("SELECT * FROM Product limit 40");

while($row = mysql_fetch_array($result))
{
echo nl2br($row['re_mark']);  //就是这行报错了
}
Copy after login

re_mark字段类型是:text

如果把re_mark改成id字段,倒是不报错。

-->$result = mysql_query("SELECT * FROM Product limit 40");

while($row = mysql_fetch_array($result))
{
echo "<img  src="%24row%5B'pic'%5D" alt=" 从mysql中取一个有内容的字段打印出来,却报错了解决办法 " >";//这样写也报错
}
Copy after login


报错内容:
Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in D:\xampp\htdocs\qry.php on line 9

------解决方案--------------------
var_dump($row['pic']); //贴出结果
------解决方案--------------------
探讨

语法错误?错在哪里

------解决方案--------------------
echo " 从mysql中取一个有内容的字段打印出来,却报错了解决办法 ";//这样写也报错
这是必然的,因为你违反了php的书写约定

这样都是可以的:
echo " 从mysql中取一个有内容的字段打印出来,却报错了解决办法 ";
echo " 从mysql中取一个有内容的字段打印出来,却报错了解决办法 ";
