Previous Comments: ------------------------------------------------------------------------ [2006-06-26 13:33:01] fala at gmx dot net Sorry, but my Web-Admin doesn't want to upgrade to a daily snapshot for security reasons... Did you fix anything and wanted me to verify the fix? Or did you just want me to try and see if the bug occurs in the newest version? ------------------------------------------------------------------------ [2006-06-22 18:55:52] tony2001@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.2-win32-latest.zip ------------------------------------------------------------------------ [2006-06-22 17:07:55] fala at gmx dot net var_dump("Client",mysqli_get_client_version(), "Server", mysqli_get_server_version()); -> string(6) "Client" int(50022) string(6) "Server" int(50022) Our Server Admin changed the PHP Version to 5.0.4, but the Bug still occurs. ------------------------------------------------------------------------ [2006-06-22 16:45:19] andrey@php.net Hi, I wasn't able to reproduce. Could you add the following to your script and give the output : var_dump("Client",mysqli_get_client_version(), "Server", mysqli_get_server_version()); Thanks andrey@lmy004:~/dev/5_0> sapi/cli/php /tmp/a.php string(9) "5.0.6-dev" ID: "64", V1: "2", V2: "0.85000002384186", V3: "1" andrey@lmy004:~/dev/5_1> sapi/cli/php /tmp/a.php string(9) "5.1.5-dev" ID: "64", V1: "2", V2: "0.85000002384186", V3: "1" andrey@lmy004:~/dev/5_2> sapi/cli/php /tmp/a.php string(9) "5.2.0-dev" ID: "64", V1: "2", V2: "0.85000002384186", V3: "1" andrey@lmy004:~/dev/6_0> sapi/cli/php /tmp/a.php string(9) "6.0.0-dev" ID: "64", V1: "2", V2: "0.85000002384186", V3: "1" ------------------------------------------------------------------------ [2006-06-22 11:31:32] fala at gmx dot net Description: ------------ MySQLi prepared statement fetch() returns incorrect values and binds them in the incorrect order. Code works with PHP 5.0.3, but not with 5.1.4 (5.1.2 was also tested and erronous as well). The following code shows a sample DB Setup with MySQL 5.0.22 on a Debian System, and the fetch statement that causes the bug. Reproduce code: --------------- CREATE TABLE foo ( ID int(11) NOT NULL auto_increment, value_f_1 float NOT NULL default '0', value_f_2 float NOT NULL default '0', value_f_3 float NOT NULL default '0', PRIMARY KEY (ID) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=97 ; INSERT INTO foo VALUES (64, 2, 0.85, 1); ------- $sql = 'SELECT ID, value_f_1, value_f_2, value_f_3 FROM foo WHERE ID = ?'; $stmt = $db->prepare( $sql ) OR die('...'); $stmt->bind_param( 'i', 64 ); $stmt->execute(); $stmt->store_result(); $stmt->bind_result($ID, $value_f_1, $value_f_2, $value_f_3); $stmt->fetch(); echo 'ID: "'.$ID.'", V1: "'.$value_f_1.'", V2: "'.$value_f_2.'", V3: "'.$value_f_3.'"'; Expected result: ---------------- (Output with PHP 5.0.3) ID: "64", V1: "2", V2: "0.850000023842", V3: "1" Actual result: -------------- (Output with PHP 5.1.4) ID: "64", V1: "4.4847901283E-34", V3: "2", V3: "0.850000023842" ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37884&edit=1
