approachable PHP correctly configures mysqlapache environment

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(), obviously mysql cannot be found There are a lot of corresponding libraries on Baidu. It is too complicated to copy the lib library of mysql and copy it to the system32 directory of windows. In fact, the correct configuration should be to add the following settings to the httpd.conf file of apache:

Copy the 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 Previous;
extension=php_mysql.dll
The last step is to add your PHP installation path to the system environment variable (note that it is a system environment variable, not a user environment variable) path. After the setting is successful, you should use phpinfo() You can see your PHP installation directory in the path of the Apache Environment section, 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, haha!
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. Zip the zip of php (such as 5.2.17 or 5.3.1) Unzip the package to a directory, such as D:php-5.3.1
3. Add the following section at the end of apache’s httpd.conf file:

Copy the 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 communicate with apache normally Combined, 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! ^_^

The above introduces approachable PHP to correctly configure the mysqlapache environment, including approachable aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
