Phpinfo () is used to list PHP configurations and check whether mysql configuration parameters exist;
Check whether the php. ini file is modified for you;
Check whether the php_mysql.dll Extension folder exists.

The phpinfo () mysql part is like this. it seems that the version is my previous version. I used mysql 5.0 in the past and now I have changed it to version 5.5.10.

"Check if php_mysql.dll exists in the Extension folder". Where can I find it? I never encountered this during installation.

Check if there is any original MYSQL program. If yes, close it. the mysql running on the PHP server should be okay !!

On line 6? Paste it to see the connection you wrote --!

On line 6? Paste it to see the connection you wrote --! $ Dbhost = 'localhost ';
$ Dbuser = 'root'; // mysql username
$ Dbpass = 'root'; // mysql password
$ Dbname = 'training'; // mysql database name
$ Link = mysql_connect ($ dbhost, $ dbuser, $ dbpass );
If (! $ Link) echo "fail ";
Else echo "success ";
Mysql_close ();
?>
I tried it out to a friend yesterday, and the running result was success. I also read his php configuration file, which is the same as mine, but we use different mysql versions, his 5.1, my 5.5, is mysql version different? php. is the configuration of ini different?

Why can't I find the specified module?

Try using mysqli_connect (). you can see if the configuration file of your php. ini in the system has been modified. or check whether mysql is supported in phpinfo (); disable?

Dude, I think it's a problem with your php version. it's not only about IPVs and unix, but also about multithreading. although I'm a newbie, I 've configured the environment for two weeks before I can give my software name. you see
Apache: httpd-2.2.17-win32-x86-openssl-0.9.8o.msi
Mysql: mysql-5.5.10-win32.msi
Php: php-5.2.17-Win32-VC6-x86.zip
Among them, php is divided into VC6 and VC9. you can see what your situation is. go to the official website and take a look at the Chinese on the left. upload my installation file to you
I think vista is similar to yours.

After removing the dll file, you also need to set it in win7 to allow the operating system to find the dll file.
The method is as follows:
Right-click "computer"-> Properties-> Advanced System Settings-> Select "Advanced tab"-> "environment variables" in the lower right corner-> select Path in the following system variable box, click edit->
Add "; C: \ PHP \ ext" to the variable value (excluding parentheses)
(My php is installed in the c root directory, so if you load program files, you should write "; C: \ Program Files \ PHP; C: \ Program Files \ PHP \ ext ")
Note: Do not delete the original variable value, but add it after the variable value.
Then restart the instance to make it take effect only after it is restarted.

Correct the error:
Select the "Advanced" tab->

In fact, this problem is generally not a problem. You cannot find the mysql module when running phpinfo.
Search for the php. ini file in C: \ Windows and check the file before extension = php_mysql.dll. Do not create extension = php_m ssql. dll. These two images are compared, and a file must be copied to the system32 directory,
Libmysql. dll, which is found in php. ini:
Extension_dir = "./"
Change it to the absolute path of the ext subdirectory in your php installation directory. For example, my:
Extension_dir = "C:/php/ext /"
This step is important. Otherwise, php cannot find the php_mysql.dll module and cannot load it.
Restart your computer or apache. if you run the phpinfo command containing mysql, the load is successful. Otherwise, the load is successful... You know!

Solved! Hahahaha! It turns out that the semicolon before extension_dir = "F:/php/ext" does not go

This is the details! The day has not been completed !!!!

It's amazing !!!
