PHP8.0的正式版早已发布，本文就介绍下它的安装，并使用laravel对比下PHP7。
PHP8.0的正式版早已发布，本文就介绍下它的安装，并使用laravel对比下PHP7【推荐：PHP视频教程】
安装与配置
本次使用的操作系统Ubuntu 18.04.4 LTS
安装
1.准备必要库
apt-get install -y autoconf libxml2-dev libsqlite3-dev \
libcurl4-openssl-dev libssl-dev libonig-dev libtidy-dev zlib1g-dev
2.去官网下载8.0正式版 https://www.php.net/releases/8.0/en.php
3.解压安装
tar php-8.0.0.tar.gzcd php-8.0.0
./configure --prefix=/opt/php8 --with-config-file-path=/opt/php8/etc \
--enable-fpm --enable-mysqlnd --enable-opcache --enable-pcntl \
--enable-mbstring --enable-soap --enable-zip --enable-calendar \
--enable-bcmath --enable-exif --enable-ftp --enable-intl --with-mysqli \
--with-pdo-mysql --with-openssl --with-curl --with-gd --with-gettext \
--with-mhash --with-openssl --with-mcrypt --with-tidy --enable-wddx \
--with-xmlrpc --with-zlibmakemake installcp php.ini-production /opt/php/etc/php.inicd /opt/php8/etccp php-fpm.conf.default php-fpm.confcp ./php-fpm.d/www.conf.default ./php-fpm.d/www.conf
4.做个软连接
ln -s /opt/php8/bin/php /usr/bin/php8
5.安装composer
cd /opt/php8/bin/curl -sS https://getcomposer.org/installer | php8ln -s /opt/php8/bin/composer.phar /usr/bin/composer8
composer8 config -g repo.packagist composer https://mirrors.aliyun.com/composer/
6.添加一个php8.0的system service
vim /lib/systemd/system/php8.0-fpm.service
内容如下
[Unit]
Description=The PHP 8.0 FastCGI Process Manager
Documentation=man:php-fpm8.0(8)
After=network.target
[Service]
Type=simple
PIDFile=/var/run/php8.0-fpm.pid
ExecStart=/opt/php8/sbin/php-fpm --nodaemonize --fpm-config /opt/php8/etc/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID
[Install]
WantedBy=multi-user.target
配置
fpm-fpm，php.ini配置
和PHP7一样，注意下用户权限
opcache配置
PHP8多了一个jit配置，如下
[opcache]
zend_extension=opcache.so
opcache.enable=1
opcache.jit_buffer_size=100M
opcache.jit=1255
启动
systemctl start php8.0-fpm
laravel
创建一个laravel项目【推荐：laravel视频教程】
cd /opt/web
composer8 create-project --prefer-dist laravel/laravel php8
配置一下.env文件
nginx配置
nginx的配置和PHP7的一致
server {
listen 94;
access_log /tmp/test94.log main;
root /opt/web/php8/public;
index index.php index.html index.htm;
location / {
try_files $uri $uri/ /index.php?$query_string;
location ~ \.php {
fastcgi_pass unix:/run/php/php8.0-fpm.sock;
fastcgi_index /index.php;
include fastcgi_params;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
添加一个接口
laravel7的路由写法在laravel8中有点问题，改下RouteServiceProvider.php的写法。 比如API路由,将$this->namespace改为App\Http\Controllers\Api。
public function boot()
$this->configureRateLimiting();
$this->routes(function () {
Route::prefix('api')
->middleware('api')
->namespace('App\Http\Controllers\Api')
->group(base_path('routes/api.php'));
Route::middleware('web')
->namespace($this->namespace)
->group(base_path('routes/web.php'));
});
其他一样，不用修改。
加个测试接口看看：
Route::get('/test','WxController@test');
test接口查一条数据并返回
<?phpnamespace App\Http\Controllers\Api;use App\Models\WareHouses;use Illuminate\Foundation\Auth\Access\AuthorizesRequests;use Illuminate\Foundation\Bus\DispatchesJobs;use Illuminate\Foundation\Validation\ValidatesRequests;use Illuminate\Http\Request;use Illuminate\Routing\Controller as BaseController;class WxController extends BaseController{
use AuthorizesRequests, DispatchesJobs, ValidatesRequests;
public function test(Request $request)
return WareHouses::find(1)->toarray();
}}
对比测试PHP7
本次使用PHP7.3，接口代码和PHP8一致，两者都开启opcache。
服务器配置是1核2G，用ab简单测试下。
ab -n 100 -c 10
PHP7.3的测试结果如下：
