What's wrong with this SQL thread?

$NQL = "INSERT into ' dh_xxx ' (' email ', ' tel ', ' upass ', ' Unick ', ' sri ', ' sex ', ' photo ', ' add ', ' Sgao ', ' xli ', ' xlit ', ' ysru ', ' Ysrid ', ' Sxiao ', ' Xzuo ', ' Zwjsao ', ' Hyzkuang ', ' Addip ', ' addipt ', ' McK ') VALUES (' ". $email. "', '". $tel. "', '". Mysql_real_escape_string ($upass). "', '". Mysql_real_escape_string ($unick). "', '". $sri. "', '". $sex. "', '". $photo. "', '". $add. "',". $sgao. ",". $xli. ", '". $xlit. "',". Yxin. ", '". Yxint. "', '". $sxiao. "', '". $xzuo. "', '". Mysql_real_escape_string ($zwjsao). "', '". $hyzkuang. "', '". Getipaddress (). "', '". getIPS138 (Getipaddress ()). "',". $site ["Examine"]. ")";

mysql_query ($NQL) or Die (Mysql_error ()); Just do it, you know.

...,". Yxin. ", '". Yxint. " ...

What is it?
If it's a constant, what's the value?

mysql_query ($NQL) or Die (Mysql_error ()); Just do it, you know.

Prompt for such error: You have a error in your SQL syntax; Check the manual, corresponds to your MySQL server version for the right syntax to use near ') ' on line 1

What's the matter ah, I php small white, seek guidance

These are variables and all have values with single quotes that are non-numeric types that do not have a numeric type variable

Is the variable why not $???

Is the variable why not $???

It was leaking, I added it now, or reported the mistake:

You have a error in your SQL syntax; Check the manual, corresponds to your MySQL server version for the right syntax to use near ') ' on line 1

where Getipaddress () getIPS138 () is a function
$site ["Examine"] $site is a globally defined variable

After I have inserted these three variables and deleted them, is it normal to call the function and the global variable directly in the string?

As long as the character type field, you should enclose the value outside the quotation marks.
Echo $NQL; Look what it is.
