MySQL Question

Parsing Error with MySQL in PHP

I am currently working on a bit of code to retrieve information from a mysql server through php to be used in an android application using JSON. Unfortunately it appears i am running into errors within my PHP script`

mysql_connect("xxx","xxx","xxx"); // edited out details
$sql=mysql_query("select FName,LName from TEST where UserId=‘".$_REQUEST['userId']."‘");
while($row=mysql_fetch_assoc($sql)) $output[]=$row;

The request for the userId is supplied by a NameValuePairs variable.
the error im recieving is:

System.out(331): Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/a2275354/public_html/test.php on line 4

Anyone know what the problem is?

"select FName,LName from TEST where UserId=‘".$_RUEST['userId']."‘"


"select FName,LName from TEST where UserId='".$_REQUEST['userId']."'"

Notice the differences in the characters enveloping the ".$_REQUEST['userId']."

It seems you copied the query from an RTF document of sorts so instead of ' you wrote
