Bkjia.Com DocumentsPHP cannot connect to MYSQL. When testing the connection to mysql, the prompt 'Fatal error: Call to undefined function mysql_connect()' The environment j is: windows xp sp2 en, apache2.2, mysql5.1rc.php5.28.

After completing the configuration according to the configuration tutorial of NetEase Technology, use phpinfo() to check. Mysql was not found..., but mysql can be operated normally in the DOS window. Then, I went back and forth to see where the problem was.

All methods in this page
http://www.somacon.com/p109.php are also

Then read the logs, reinstall, and repeatedly set php.ini, my.ini, apache.conf, but still couldn’t catch up. It was really hard for me to turn around. Later, there was really no other way. .. Just use adminphp to see if I can connect, but it prompts "Cannot load mysql extension. Please check your PHP configuration". I feel like I am Mr. bean


Could this prompt be caused by PHP? What about the library files loaded to connect to mysql? After starting the apache server, I tried to delete 'php5ts.dll' and 'libmysql.dll'. It said that it cannot be deleted. It means that there are programs using these two library files. It means that there are Loaded. (Of course there are many ways to test. For example, you can use some software to view all the library files loaded by the program service. It is also possible. However, ap also said that there is a problem with the php.ini settings. Then I will not look at anything else. I Just focus on php.ini configuration.

Without superstition that php.ini is correct, I finally discovered that this line is missing from .php.ini.

PHPIniDir "your php directory"

# (for example: PHPIniDir "c:/php")

Restart the apache server, and then use the methods commonly used on the Internet

The following is the quoted content:

以下为引用的内容:
$link=mysql_connect('localhost','用户名','password');
if(!$link) echo "失败!";
else echo "成功!";
mysql_close();
?>
$link =mysql_connect('localhost','username','password');

if(!$link) echo "Failure!";else echo "Success!";mysql_close();
?>



Test it. That’s it.
My php.ini configuration


That’s it, it took a lot of time... This is the first time I encountered this problem. It can only mean that "fate" is all "fate" "Ah!

On the same machine. If .apache has been installed multiple times before, or the installation is not in the same directory, and there is more than one version, it is best to clean it up before installing mysql5.1rc. Registry Some other configuration tutorials say that you need to copy 2 dll files to system32. In fact, according to the above tutorial, because the environment variables are set, it is not necessary if you have done so before. Yes. Just delete him.
