How to install and configure PHP? The following article will introduce to you how to install and configure PHP in Windows and Linux environments. I hope it will be helpful to you!

Introduction to PHP

PHP is the "hypertext preprocessor" and is a general open source scripting language. PHP is a scripting language executed on the server side. It is similar to C language and is a commonly used website programming language. PHP's unique syntax mixes C, Java, Perl, and PHP's own syntax. It is conducive to learning and widely used. It is mainly suitable for the field of web development. Originally the abbreviation of Personal Home Page, it has been officially renamed "PHP: Hypertext Preprocessor"

Installation and configuration of PHP under Windows

1. Download

The official website download address is https://windows.php.net/download

Choose the latest version to download

More versions are introduced in the left navigation of different VC and Thread Safe.

2. Decompress

The file name can be changed to be more concise

3. Configuration

Apache installation configuration can be found here

https://blog.csdn.net/qq_45034708/article/details/108565486

#加载PHP
LoadModule php7_module 'D:/tools/php7/php7apache2_4.dll'

#将PHP配置文件加载到Apache配置文件中，共同生效
PHPIniDir 'D:/tools/php7'

#配置Apache分配工作给PHP模块，把PHP代码交给PHP处理
#即.php后缀名的文件
AddType application/x-httpd-php .php

4. php.ini file

is the php configured above. The ini file does not exist by default. It exists in development and production formats and needs to be formatted.

5. Test configuration (this step can be skipped)

Restart the Apache service , open cmd, switch to the Apache decompression directory/bin, enter the command

httpd -M

##6. Test the PHP code

<?php
	//测试
	echo &#39;hello world&#39;;
?>

Installation configuration under Linux PHP

1. Download and extract

cd /usr/local/src/ #切换目录
wget http://cn2.php.net/distributions/php-7.4.10.tar.bz2 #下载
wget http://xmlsoft.org/downloads.html/
tar jxvf php-7.4.10.tar.bz2 #解压

2. Install

cd /usr/local/src/php-7.4.10
./configure --prefix=/usr/local/php7 --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php7/etc --with-mysql=/usr/local/mysql --with-pdo-mysql=mysqlnd --with-mysqli --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif --enable-fpm

3. php.ini

cp php.ini-development php.ini /usr/local/php7/ #拷贝
cp php.ini /usr/local/php7/
/usr/local/php7/bin/php -m #查看PHP加载模块
/usr/local/apache2.4/bin/apachectl -M #查看httpd加载模块

4. Configure Apache

vim /usr/local/apache2.4/conf/httpd.conf #编辑配置文件
#修改以下四点
#1.ServerName 195行
ServerName www.example.com:80
#2.Directory 204行
<Directory />
    AllowOverride none
    Require all granted
</Directory>
#3.DirectoryIndex 253行
<IfModule dir_module>
    DirectoryIndex index.html index.php
</IfModule>
#4.AddType 391行
AddType application/x-httpd-php .php

:wq #保存退出(先按ESC)
/usr/local/apache2.4/bin/apachectl -t #测试配置语法
/usr/local/apache2.4/bin/apachectl graceful #重新加载配置文件

5、启动服务

/usr/local/apache2.4/bin/apachectl start
ps -ef|grep httpd #查看httpd进程
netstat -lntp|grep 80 #查看80端口
curl localhost #测试

6、测试

iptables -I INPUT -p tcp --dport 80 -j ACCEPT #开放80端口或配置服务器安全组
vim /usr/local/apache2.4/htdocs/test.php #编辑测试文件
<?php
	phpinfo();
?>
:wq #保存退出(先按ESC)

 按此步骤下来就能成功了。
