Description:
------------
Create a PDO_MYSQL connection ($db in the example code). Prepare a query with high ascii values between single quotes (update queries are often affected) and one or more named parameters. Execute the query. 

Reproduce code:
---------------
$query = "
	SELECT		'?' as test
	FROM		test
	WHERE		id = :id";
$stm = $db->prepare($query);
$stm->execute(array(":id" => 1));

Expected result:
----------------
No errors, query is correct when executed directly under mysql.

Actual result:
--------------
SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ':id' at line 3

Changing the single quotes in the query to double seems to fix the problem.

Please try using this CVS snapshot:

  http://snaps.php.net/php5.1-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5.1-win32-latest.zip

Can't reproduce.

Tried the snapshot, and the problem still exists. Perhaps you aren't seeing the error because you need to explicitly set exception handling:

$db = new PDO("mysql:host=$dbHost;dbname=$dbName", $dbUser, $dbPass);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

[.. and then the code ..]

oops, changed the summary
 [2006-03-21 15:41 UTC] [email protected] 
What is the charset of the server/connection?
 [2006-03-22 19:53 UTC] albert at jool dot nl 
Charset of the connection is default ISO-8859-1 (you need to explicitly set another charset in the dsn), and the charset of any mysql table used is default latin1 - if any solution requires changing any of these settings, consider changing PHP first :). 

Anyhow, notice that the query _parsing_ fails, not the query itself. The double-quote fix isn't working btw - the error just didn't show up anymore as output (which is also strange!).
 [2006-12-05 18:06 UTC] [email protected] 
This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
 
Thank you for the report, and for helping us make PHP better.
