語法錯誤，在PHP

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"; 

意外T_CONSTANT_ENCAPSED_STRING在查詢字符串上面的代碼，即在側mysql_quey串

我們得到了以下錯誤

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

在查詢字符串「\ n」包租不識別爲字符串多數民衆贊成爲什麼以上錯誤得到

Answer 1

你需要轉義雙引號爲：\"而不是""

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

未轉義的"會提前終止字符串。

實施例：

這是不正確的："A " is a double quote"
這是正確的："A \" is a double quote"
