# PHP8 released – PHP7升级PHP8 #

打开CSDN一看，天哪，首页居然写着: PHP8发布了，不信不信，拿来这么快的，赶快去官网看看  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3R3eHdqaA_size_16_color_FFFFFF_t_70][]  
再官网确认的压力下，我终于松了一口气  
这回不会又要来一次PHP5转PHP7吧…于是，我耐心的开始读首页上的那篇文章…[https://blog.csdn.net/asasd101/article/details/110233139][https_blog.csdn.net_asasd101_article_details_110233139]  
这篇文章讲的都是PHP8的新特性，方便程序员们的简单语法改进和安全改进  
嗯，这就好，至少兼容PHP7，同时如果你想改进代码也可以慢慢来，反正兼容，再升级PHP9之前改完就行了  
现在就开始更新PHP8吧!  
[https://www.php.net/releases/8.0/en.php][https_www.php.net_releases_8.0_en.php]  
[https://www.php.net/downloads][https_www.php.net_downloads]  
这两个连接都是PHP8的下载连接，点进去

向下滑，选择Thread Safe版本，x86或x64自己选

点击zip进行下载

### 如果你是初次安装PHP8 ###

你得先安装Apache24  
[https://www.apachehaus.com/cgi-bin/download.plx][https_www.apachehaus.com_cgi-bin_download.plx]  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3R3eHdqaA_size_16_color_FFFFFF_t_70 6][]  
点击下载解压到C:/Apache24

将下载的`.zip`解压到`C:/php`

在`C:/Apache24/Apache24/conf/httpd.conf`(Apache24路径)中添加几行

LoadModule php_module C:/php/php8apache2_4.dll
    PHPIniDir C:/php
    AddType application/x-httpd-php .php .html

其它的Apache24和PHP8配置，PHP8扩展配置可以以后自行探索，过一会儿我们将会说到启动Apache24

### 如果你是在升级PHP8 ###

将原来的php.ini复制到其它的地方，如`C:/php.ini`，然后将`.zip`解压到`C:/php`，Apache24配置的PHP路径下，注意先关掉Apache24

C:/
    ---
    |- php
        |- dev
        |- ext
        |- extras
        |- lib

Apache24的PHP路径可以在httpd.conf中找到，如果你没有配置PHP，请按照安装PHP8的步骤安装配置，如下图，`PHPIniDir`就是PHP路径

打开httpd.conf  
![2020112811031163.png][]  
![20201128110344434.png][]  
把所有的php7改成php8  
![20201128111906460.png][]  
但是注意`LoadModule php7_module C:/php/php7apache2_4.dll`应改为`LoadModule php_module C:/php/php8apache2_4.dll`而不是`LoadModule php8_module C:/php/php8apache2_4.dll`  
***总结***: 把php7改成php8，但是LoadModule php7\_module要改成LoadModule php\_module而不是php8\_module

LoadModule php_module C:/php/php8apache2_4.dll
    PHPIniDir C:/php
    AddType application/x-httpd-php .php .html

### 启动/重启Apache24 ###

先打开命令行，将路径设置为`C:\Apache24\Apache24\bin`，输入`httpd -t`检查`httpd.conf`语法

正常情况下应该输出这样的字样，如果有不同可以在评论区回复

稍后将会讲到PHP8测试
