Description:
------------
MySQLi prepared statements always return NULL bytes when running in PHP-GTK. This bug does not exist in WAMP environment. Normal queries work fine in PHP-GTK. My PHP-GTK/MySQL setup is fine.

Test script:
---------------
$test = null;
if($stmt = $mysqli->prepare("SELECT 'here 3' FROM saved_data LIMIT 1")) {	
	echo 'here 1';
	$stmt->bind_result($test);	
	$stmt->execute();
	while($stmt->fetch()) {
                echo 'here 2';
		var_dump($test);
	}
}

Expected result:
----------------
here 1
here 2
string(6) "here 3"

Actual result:
--------------
here 1
here 2
string(7) "       "

Cannot reproduce - works perfectly here

check that you do not have the wrong libmysql being loaded (not php_mysqli.dll - but the libmysql.dll that it uses - this sounds like a client mismatch)

BTW - some additional debugging suggestions for your setup - testing against WAMP is irrelevant, it's a different PHP executable in a different location with different extensions and loading different dependencies

Try your mysqli on your php-gtk install, just comment out the php-gtk extension, and see if you still get the errors

Thanks for your help. After getting mysql dll files from PHP 5.2.13NTS and copying them into PHP-GTK the problem has gone.. Must have been a version mismatch as you say! Strange that some functionality worked but not all.
