I have encountered difficulties which I believe are related to this bug as it is reported herein.  I am trying to install PHP 5.0.02 on a Windows 2k/IIS 5.x Server.  Prior to this installation the target environment was executing with PHP 4.xxx.   In this pre-installation environment I was also executing MySQL 4.0.18-nt, the same version that I am now having problems with in the context of PHP 5.0.02.  I am failing when I reach the point of making a mysql_connect(...) call.   I am fairly certain that I have caused this to fail by simply attempting to load with only the mysql library (i.e. sans mysqli).   I hope this has been of some use to you.   Good luck with your efforts to get this particular version of php up and running with MySQL.  In my own particular case, PHP is of no use to me unless it will interface with my MySQL database.

I stand corrected.   I rechecked my php.ini and discovered that I had not disabled to the loading of php_mysqli.dll.  Upon disabling that particular module I was able to resume normal execution.   Therefore, my case is no different from that originally reported by david.

My case is that I am only trying to use php_mysqli.dll to interface with MySql 5.x (using php 5.02).  I was under the impression you do not require to use both php_mysqli.dll AND php_mysql.dll - I am of the opinion you use either one or the other.  I get the message:

Fatal error: Call to undefined function mysql_connect())

When I attempt to use php_mysql.dll I get the EXPECTED error of:

"Client does not support authentication protocol requested by server; consider upgrading MySQL client"

(which is the entire reason PHP suggests php_mysqli.dll).

I have no intention of converting the MySQL 5 passwords to the old method of storage and php is of no use to me if it does not work with MySQL.

Please advise!

I would like to add that a call to phpinfo() shows that php_mysqli.dll is actually being loaded - no clue why its totally ineffective!?

I think I finally figured something out folks: 

I'm running php5, apache2 and mysql5 on a winxp machine.

In php.ini I have:
extension_dir='c:/php'
extension=php_mysqli.dll
I copied the php_mysqli.dll and libmysql.dll in my php install folder which is also my extension directory (extension_dir='c:/php').

As you can see all instructions followed as recommended throughout the web.

I created a phpinfo() test page and I get MySQLi information with no problem.

I installed phpMyAdmin and it's running fine as well.

But I started building a mysql class in php and got stuck with the "Fatal error: Call to undefined function mysql_connect()". That's when the headache began.

After about 2 hours I tried mysqli_connect() instead of mysql_connect() and the error disappeared and gave way to the next "undefined function error" still related to a mysql_ function. I soon discovered that there's a whole new set of mysqli_ functions that are part of the new library. Basically wherever you used to have mysql_ you now use mysqli_. It should however be noted that the latter version is a bit more strict when it comes to parameters passed as variables. The $linkID is often required in the function call, not optional as it used to be in the former library.

have a look: http://ca3.php.net/manual/en/function.mysqli-connect.php

I think this is a detail that should have been advertised a bit more when they were handing out mysqli.
