Topic: php_mysqli.dll not found?

[Joelk]

All of a sudden Apache isn't running correctly. A review of the error log revealed this message:

PHP Warning: PHP Startup: Unable to load dynamic library './php_mysqli.dll' - The specified module could not be found.\r\n in Unknown on line 0

I've copied the indicated module from C:\PHP\ext to C:\WINDOWS and to C:\WINDOWS\system32 in an effort to correct this, with the same result. Any advice?

Thanx, in advance.

Oh, BTW - Windows XP Home Edition Version 2002, SP 2.

re: "All of a sudden..." - Do you mean nothing changed? It was running OK then it suddenly stopped?

re:...isn't running correctly" - Do you mean PHP pages which use MySQL fail with some (unspecified) error? All your PHP pages fail?
Regular static pages still work OK, right?

Check that your php.ini file has this line:

Sorry Tom,

I should have been more precise than "not running correctly"
I just didn't know how to put it in a few words. What happens is this:

When I first installed Apache, PHP and MySql a few months ago, all was well. I was able to get a few .php screens to work. Then starting today,when I start Apache all looks well until I try to invoke the same .php files that were working before, but the Fireox window remains unchanged. This puzzled me until I remembered I could look at the error.log file to see what was happening. what I see is this

I've done everything you suggested in your reply but still get the same results. I'm stumped

That's a real stumper!

You didn't by any chance upgrade to MySQL 5.0.41? The Windows version had a bad libmysql.dll in the install. (MySQL Bug 28358)

If so - you can just replace libmysql.dll with a copy from MySQL version 5.0.40 or earlier.

If not - the only steps I can suggest are:

1. Remove php_mysqli.dll from \WINDOWS, \WINDOWS\System32, and any place else it may be.
The only copy on your system should be the one in C:\PHP\ext

2. Do the same for libmysql.dll (including C:\Apache2\bin if you put it there).
The only copy on your system should be in your MySQL directory.

3. Check that you used forward-slashes (/) - not backslashes (\) - in httpd.conf.

Then start Apache from the command line with:

Okay, I got the error message problem ironed out but now I have a new problem. when I enter
