Hello ! I've read a lot of web, news and archives for two days and i've not resolve my problem. Here it is : Configuration : Apache 1.3.20 (Win32) / PHP 4.0.5 / MySQL 3.23.39 / Windows 2000 Pro (SP2 and update ok). Services : Apache and MySQL runs as services under 'toto' account. Note : i use apache with php module As written in http://www.mysql.com/doc/A/c/Access_denied.html, i've checked all my mySQL configuration and it seems good. I can log on my database with >mysql -u toto -p12345 titi and it works fine. as they said : "If you are able to connect using the mysql client, there is a problem with your program and not with the access privileges." Note : * select host,user from mysql.user gives (localhost,root) and (localhost,toto) * select host,db,user from db gives (localhost,toto,titi) [I've removed anonymous users and hosts that are not 'localhost'] So look at the (very simple !) HTML/PHP : <html><head><title>try</title></head> <body> <?php $dbhost="localhost"; $dbuser="toto"; $dbpass="12345"; $dbname="titi"; $conn = mysql_connect($dbhost,$dbuser,$dbpass) or die("bad Connection"); mysql_select_db($dbname,$conn) or die("titi database not found"); mysql_close($conn); ?> </body></html> and i have this message : "Warning: MySQL Connection Failed: Access denied for user: 'toto@localhost' (Using password: NO)" the only way to match this warning is to connect with mysql client without the password : >mysql -u toto titi "ERROR 1045: Access denied for user: 'dnd3e@localhost' (Using password: NO)" [If it was a password that doesn't match i should find at the end (Using password: YES), isn't it ? and with same parameters, the mysql client connect without problems] I conclude that PHP script connect without the password argument ! As it seems impossible, i ask on this list some help thanks for your help regards, rashkatsa -- PHP Windows Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
