PHP correctly configures mysql (apache environment)_PHP tutorial

I wrote a php file to test mysql as follows:

Copy the code The code is as follows:

$ link=mysql_connect('localhost','root','root');
if(!$link) echo "Failure!";
else echo "Success!";
mysql_close();
?>

The result is an error: Fatal error: Call to undefined function mysql_connect(). It is obvious that the corresponding library for mysql cannot be found. Baidu has a lot of them, and what is the copy of mysql? The lib library is copied to the system32 directory of Windows. It is too complicated. In fact, the correct configuration should be to add the following settings to the httpd.conf file of apache:

Copy code The code is as follows:

LoadModule php5_module d:/tools/php-5.3.1/php5apache2_2.dll
AddType application/x-httpd-php .php
PHPIniDir d: /tools/php-5.3.1

Note that the last line is the key, telling apache where your php configuration file is, otherwise you have to copy the php.ini file to the windows system directory . Generally, we can complete the combination of apache and php through configuration here. In the php.ini file, you only need to modify the following places:

# Modify the php extension library directory to your actual path
extension_dir = "D:/tools/php-5.3. 1/ext"

# Remove the previous;
extension=php_mysql.dll
The last step is to add it to the system environment variable (note that it is a system environment variable, not a user environment variable) path After setting your PHP installation path successfully, you should be able to see your PHP installation directory in the path of the Apache Environment section through phpinfo(), otherwise the environment variables are not configured successfully (note, restart apache after configuring the environment variables ).

After completing these steps, you can connect to the database correctly, but the premise is that the integration of your apache and php is normal, and then consider this mysql configuration. If the effect is not achieved, you can question me, hehe!

In summary, the correct configuration steps for integrating apache and php (including mysql) under the windows platform are as follows:

1. Install apache and ensure that apache can run normally alone

2 . Unzip the zip package of PHP (such as 5.2.17 or 5.3.1) to a directory, such as D:php-5.3.1

3. Add the following paragraph at the end of the httpd.conf file of apache:

Copy code The code is as follows:

# php5 support
LoadModule php5_module D:/php-5.3.1/php5apache2_2 .dll
AddType application/x-httpd-php .php
PHPIniDir D:/php-5.3.1

4. Environment variables in the operating system (must be system variables) Add the D:/php-5.3.1 path

to the path of non-user variables) 5. Rename php.ini-dist in the php installation directory to php.ini, and modify the following content:

# Set the php extension file directory
extension_dir = "D:/php-5.3.17/ext"

# Enable the mysql extension and remove the previous; comment
extension=php_mysql .dll

After completing the above 5 steps, your php will be able to be combined with apache normally, and common problems such as: PHP Warning: PHP Startup: Unable to load dynamic library..., Fatal error: Call to undefined function mysql_connect()... will also be gone forever! ^_^
