Versi rasmi PHP8.0 telah dikeluarkan untuk masa yang lama Artikel ini akan memperkenalkan pemasangan dan penggunaannya laravel untuk membandingkan PHP7 [Disyorkan: Tutorial video PHP]
Sistem pengendalian yang digunakan kali iniUbuntu 18.04.4 LTS
Pemasangan
1 Sediakan perpustakaan yang diperlukan
apt-get install -y autoconf libxml2-dev libsqlite3-dev \ libcurl4-openssl-dev libssl-dev libonig-dev libtidy-dev zlib1g-dev
2 Pergi ke tapak web rasmi untuk memuat turun versi rasmi 8.0 https://www.php.net /releases/8.0/en.php
3 Buka zip dan pasang
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. Buat pautan lembut
ln -s /opt/php8/bin/php /usr/bin/php8
5
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. Tambah perkhidmatan sistem php8 .0
vim /lib/systemd/system/php8.0-fpm.servicekandungan adalah seperti berikut
[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
konfigurasi
fpm-fpm, konfigurasi php.ini
Sama seperti PHP7, beri perhatian kepada kebenaran penggunakonfigurasi opcache
PHP8 mempunyai konfigurasi jit tambahan, seperti berikut[opcache] zend_extension=opcache.so opcache.enable=1 opcache.jit_buffer_size=100M opcache.jit=1255
Mula
systemctl start php8.0-fpmlaravel
Buat projek laravel [Disyorkan: tutorial video laravel]
cd /opt/web composer8 create-project --prefer-dist laravel/laravel php8Konfigurasikan fail .env
konfigurasi nginx
Konfigurasi bagi nginx konsisten dengan PHP7server { 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; } }
Tambah antara muka
Kaedah penghalaan laravel7 mempunyai beberapa masalah dalam laravel8. Sila tukar kaedah penulisan. RouteServiceProvider.php
Contohnya, untuk penghalaan API, tukar
kepada $this->namespace
. AppHttpControllersApi
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')); }); }Yang lain pun sama, tak perlu ubah suai. Tambahkan antara muka ujian untuk melihat:
Route::get('/test','WxController@test');
Antara muka menyemak sekeping data dan mengembalikannyatest
<?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(); }}Ujian perbandingan PHP7
