语法错误，php中意外的T_Constant_encapsed_string [闭合

Question

mysql_connect("localhost","root","");
mysql_select_db("hitnrunf_db");

$result=mysql_query("select * from jos_users INTO OUTFILE 'users.csv' FIELDS ESCAPED BY '""' TERMINATED BY ',' ENCLOSED BY '"'
 LINES TERMINATED BY '\n' ");

header("Content-type:  text/plain");
header("Content-Disposition: attachment; filename=your_desired_name.xls");
header("Content-Transfer-Encoding: binary");
header("Pragma: no-cache");
header("Expires: 0");
print "$header\n$data";

在上面的代码中，在查询字符串中IE字符串侧面mysql_quey中的字符串

我们正在遵循以下错误

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING in C:\wamp\www\samples\mysql_excel\exel_outfile.php on line 8

在查询字符串' n'章程中没有识别为字符串，这就是为什么上述错误获取

Answer 1

您需要逃脱双引号： \" 代替 ""

$result=mysql_query("select * from jos_users INTO OUTFILE 'users.csv' FIELDS ESCAPED BY '\"' TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\n' ");

一个未散布的 " 将过早终止字符串。

例子：

这是不正确的： "A " is a double quote"
这是对的： "A \" is a double quote"
