This article describes the PHP modular installation method. Share it with everyone for your reference, the details are as follows:

PHP (Hypertext Preprocessor) is a simple but very powerful scripting language. The installation and basic configuration process of Apache2.0.53 php5.2.1 based on the WindowsXP sp2 operating platform is recorded below for reference:

1. First download the following programs from official websites:

1. apache_2.0.53-win32-x86-no_ssl.exe
2. php-5.2.1-Win32.zip (binary compressed package)

2. Installation and configuration process:

1. Install apache web server:

Double-click the installation file apache_2.0.53-win32-x86-no_ssl.exe and install it in the D:/Apache directory (I created a new Apache folder on the D drive),

------------------------------------------------- --------
Note: The following problems may occur during the installation process:
OS 10048 Normally each socket address (protocol/network address/port) is only allowed to be used once:
make_sock: could not bind to address 0.0.0.0:80..." It is usually caused by IIS occupying port 80
Two solutions:
1. Open the Control Panel->Services, find the IIS admin service, close and disable
2. If you don’t want to close the IIS service, you can change the port used by apache to another port
Change Listen 80 in apache2/conf/httpd.conf to Listen (the port you want to use) such as Listen 8080
But at this time, when you access the web service under your apache, you need to add the port number after the domain name
For example: http://localhost:8080
-------------------------------------------------- -----

To test whether Apache is installed successfully, enter in the browser: http://localhost:8080/http://localhost If you can see the Apache logo feather, Congratulations!!!

2. Install PHP:

Extract the contents of php-5.2.1-Win32.zip to D:/PHP (I created a new PHP folder on the D drive), find php.ini-dist in the php directory and rename it to php.ini And copy it to the windows directory. Then copy php5ts.dll and libmysql.dll in the D:/PHP directory to the system directory (under windows/systems32).

Configure httpd.conf in apache

Open the file D:/Apache2/conf/httpd.conf
Find AddDefaultCharset ISO-8859-1 and change it to AddDefaultCharset GB2312 (make the default language encoding Simplified Chinese)
Find DocumentRoot "D:/Apache2/htdocs" and change it to your WEB directory (optional). For example, mine is DocumentRoot "G:/Web Project"
Find DirectoryIndex index.html index.html.var and add index.htm index.php

Select the installation mode: Modular mode installation or CGI mode installation (select one)

Modular installation configuration

Find the line #LoadModule ssl_module modules/mod_ssl.so and add a line after this line:

LoadModule php5_module d:/php/php5apache2.dll

Where d:/php/php5apache2.dll is the location of php5apache2.dll in your php directory

Note: LoadModule php5_module d:/php/php5apache2.dll   
//Note: C:/php5/php5apache2.dll is the corresponding path where you install php. Do not confuse php5apache2.dll with php5apache2_2.dll.

php5apache2.dll only applies to apache version 2.0.

If it is apache2.2.* or above, "Cannot load C:/php/php5apache2.dll into server: The specified module could not be found." or: "The requested operation" may appear. has failed"

Find the line AddType application/x-gzip .gz .tgz and add a line after this line

AddType application/x-httpd-php .php

CGI installation configuration

Find the AddType application/x-gzip .gz .tgz line and add the following:

ScriptAlias /php/ "d:/php/"
AddType application/x-httpd-php .php
Action application/x-httpd-php "/php/php-cgi.exe"

Note: The full English name of CGI is Common Gateway Interface, which is usually translated as common gateway interface. It is an interface for the HTTP server to communicate with other programs on the machine. This "other program" can be written in any computer language. It obtains input from the HTTP server through the CGI interface, and then sends the running results to the HTTP server through the CGI interface, and the HTTP server sends the results to the browser.

The emergence of CGI has changed the WEB from static to dynamic. As the Web becomes more and more popular, many websites need dynamic pages to interact with viewers. The shortcomings of CGI methods are becoming more and more prominent. Because HTTP needs to generate a dynamic page, the system must start a new process to run the CGI program. Continuous forking is a very time- and resource-consuming task. Here comes FastCGI.

FastCGI is like a long-live CGI. It can be executed all the time. As long as it is activated, it will not take time to fork every time (this is the most criticized fork-and-function of CGI). -execute mode).

At this point the PHP environment has basically been configured successfully

Create a file named test.php in the WEB root directory (such as my D:/website) with the following content

Restart apache service

Open http://localhost/test.php with a browser or in LINUX system: /usr/local/php/bin/php -f test.php

It’s OK if you can see the php configuration output information

Note: Modular installation mod_php is to use PHP as a built-in module of APACHE. Let the apache http server itself support the PHP language, without starting the PHP interpreter for every request to interpret PHP.
